ARC WELDING SAFETY PRECAUTIONS
WARNING
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN
AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR.
In welding, as in most jobs, exposure to certain hazards occurs. Welding is safe when precautions are taken. The
safety information given below is only a summary of the more complete safety information that will be found in the
Safety Standards listed on the next page. Read and follow all Safety Standards.
HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY
QUALIFIED PEOPLE.
ARC WELDING can be hazardous.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomatic or automatic
wire welding, the wire, wire reel, drive roll housing, and
all metal parts touching the welding wire are
electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the
work or ground.
4. Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according
to OSHA 29 CFR 1910.147 (see Safety Standards).
5. Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
6. Always verify the supply ground – check and be sure that input
power cord ground wire is properly connected to ground terminal
in disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
7. When making input connections, attach proper grounding
conductor first – double-check connections.
8. Frequently inspect input power cord for damage or bare wiring –
replace cord immediately if damaged – bare wiring can kill.
9. Turn off all equipment when not in use.
10. Do not use worn, damaged, undersized, or poorly spliced cables
.
11. Do not drape cables over your body.
12. If earth grounding of the workpiece is required, ground it directly
with a separate cable – do not use work clamp or work cable.
13. Do not touch electrode if you are in contact with the work, ground
,
or another electrode from a different machine.
14. Use only well-maintained equipment. Repair or replace
damaged parts at once. Maintain unit according to manual.
15. Wear a safety harness if working above floor level.
16. Keep all panels and covers securely in place.
17. Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
ARC RAYS can burn eyes and skin;
NOISE can damage hearing; FLYING
SLAG OR SPARKS can injure eyes.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays that
can burn eyes and skin. Noise from some processes
can damage hearing. Chipping, grinding, and welds
cooling throw off pieces of metal or slag.
NOISE
1. Use approved ear plugs or ear muffs if noise level is high.
ARC RAYS
2. Wear a welding helmet fitted with a proper shade of filter to
protect your face and eyes when welding or watching (see ANS
I
Z49.1 and Z87.1 listed in Safety Standards).
3. Wear approved safety glasses with side shields.
4. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.
5. Wear protective clothing made from durable, flame-resistan
t
material (wool and leather) and foot protection.
FUMES AND GASES can be hazardous
to your health.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for metals, consumables, coatings,
cleaners, and degreasers.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained
watchperson nearby. Welding fumes and gases can displace air
and lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding
process, be sure to treat them carefully.
1. Protect compressed gas cylinders from excessive heat,
mechanical shocks, slag, open flames, sparks, and arcs.
2. Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other electrical circuits.
4. Never drape a welding torch over a gas cylinder.
5. Never allow a welding electrode to touch any cylinder.
6. Never weld on a pressurized cylinder – explosion will result.
7. Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
8. Turn face away from valve outlet when opening cylinder valve.
9. Keep protective cap in place over valve except when cylinder is
in use or connected for use.
10. Read and follow instructions on compressed gas cylinders
,
associated equipment, and CGA publication P-1 listed in Safety
Standards.
sr1.1.1 2/94
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks, drums,
or pipes, can cause them to blow up. Sparks can fly off
from the welding arc. The flying sparks, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode to metal
objects can cause sparks, explosion, overheating, or
fire. Check and be sure the area is safe before doing
any welding.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks, drums, or pipes
,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
8. Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire a
t
contact tip when not in use.
11. Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
12. Remove any combustibles, such as a butane lighter or matches
,
from your person before doing any welding.
WARNING
ENGINES can be hazardous.
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1. Use equipment outside in open, well-ventilated areas.
2. If used in a closed area, vent engine exhaust outside and away
from any building air intakes.
ENGINE FUEL can cause fire or
explosion.
Engine fuel is highly flammable.
1. Stop engine and let it cool off before checking or adding fuel.
2. Do not add fuel while smoking or if unit is near any sparks or
open flames.
3. Do not overfill tank – allow room for fuel to expand.
4. Do not spill fuel. If fuel is spilled, clean up before starting
engine.
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards closed and
securely in place.
2. Stop engine before installing or connecting unit.
3. Have only qualified people remove guards or covers for
maintenance and troubleshooting as necessary.
4. To prevent accidental starting during servicing, disconnec
t
negative (–) battery cable from battery.
5. Keep hands, hair, loose clothing, and tools away from moving
parts.
6. Reinstall panels or guards and close doors when servicing is
finished and before starting engine.
SPARKS can cause BATTERY
GASES TO EXPLODE; BATTERY
ACID can burn eyes and skin.
Batteries contain acid and generate explosive
gases.
1. Always wear a face shield when working on a battery.
2. Stop engine before disconnecting or connecting battery
cables.
3. Do not allow tools to cause sparks when working on a battery
.
4. Do not use welder to charge batteries or jump start vehicles.
5. Observe correct polarity (+ and –) on batteries.
STEAM AND PRESSURIZED HOT
COOLANT can burn face, eyes, and
skin.
It is best to check coolant level when engine is cold
to avoid scalding.
1. If the engine is warm and checking is needed, follow steps 2
and 3.
2. Wear safety glasses and gloves and put a rag over cap.
3. Turn cap slightly and let pressure escape slowly before
completely removing cap.

EMF INFORMATION
The following is a quotation from the General Conclusions Section of
the U.S. Congress, Office of Technology Assessment, Biological
Effects of Power Frequency Electric & Magnetic Fields –
Background Paper, OTA-BP-E-53 (Washington, DC: U.S.
Government Printing Office, May 1989): “. . . there is now a very large
volume of scientific findings based on experiments at the cellular
level and from studies with animals and people which clearly
establish that low frequency magnetic fields can interact with, and
produce changes in, biological systems. While most of this work is
of very high quality, the results are complex. Current scientific
understanding does not yet allow us to interpret the evidence in a
single coherent framework. Even more frustrating, it does not yet
allow us to draw definite conclusions about questions of possible risk
or to offer clear science-based advice on strategies to minimize or
avoid potential risks.”
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around the body.
4. Keep welding power source and cables as far away as practical.
5. Connect work clamp to workpiece as close to the weld as
possible.
About Pacemakers:
The above procedures are among those also normally
recommended for pacemaker wearers. Consult your doctor for
complete information.

SECTION 3 – OPERATIONAL TERMS
The following is a list of terms and their definitions as they apply to this interface unit:
General Terms:
Adaptive Pulse Welding When the “adaptive pulse” welding process is selected, the unit will automati-
cally regulate pulse frequency in order to maintain a constant arc length, re-
gardless of change in welding wire stickout.
Abk (Background
Amperage)
Abk is the low weld current. Background current preheats welding wire and
maintains the arc. When background current is too low, the arc is unstable and
hard to maintain.
Apk (Peak Amperage) Apk is the high pulse of welding current. Peak current melts the welding wire
and forms a droplet. The droplet is forced into the weld puddle.
Inductance In short circuit GMAW welding, an increase in inductance will decrease the
number of short circuit metal transfers per second (provided no other changes
are made) and increase the arc-on time. The increased arc-on time makes the
pool more fluid.
PPS (Pulses Per Second) PPS, pulse rate, and frequency (Hz) are used interchangeably. A PPS or pulse
rate of 60 Hz means 60 pulses of current are produced each second.
PWms (Pulse Width in
Milliseconds)
PWms is the time spent at peak current (1.2 ms is .0012 seconds). This time
must be long enough to form a droplet of welding wire. The stiffness or fluidity
of the molten weld puddle is controlled by PWms.
Synergic Synergic refers to the unit’s ability to use preprogrammed pulse parameters to
determine the actual pulse settings of Peak Amperage, Background Amperage,
Pulse Frequency and Pulse Width at any specific wire feed speed setting.
Trim Term used to represent arc length adjustments in pulse programs. Increasing
trim increases the actual arc length. Likewise, decreasing trim shortens arc
length. Trim is replaced by volts in MIG programs.
OM-172 324 Page 5
Pulse Panel Terms:
Card Mode Is used to select use of the optional data card storage and retrieval capabilities.
Process Mode Is used to select the type of process to be used, including Pulse, Adaptive
Pulse, or Mig.
Sequence Mode Is used to select and program the weld sequences which include preflow, run-
in, weld, crater, burnback, and postflow.
Setup Screen Terms:
Access Code NOTE: The optional Data Card is required to activate this feature. With code
off, access to the setup displays is not restricted. With code on, the operator
must know and enter the access code to access or change any of the setup
displays.
To use code, press Parameter Select button to enter access code. When the
correct letter is entered, the indicator automatically moves to the next charac-
ter. When the final access code letter is entered, the display automatically
changes to the initial setup display.
Arc Start NOTE: Do not use the Hot Start setting for .035 in (9 mm) or smaller wire. Use
the Hot Start mode for pulse welding with 450 Ampere Inverter Model when
high initial weld current is necessary to start large diameter welding wires.
When in Hot Start, the 450 Ampere Inverter Model starts the arc in the CV
mode and switches to CC once the arc is started. Do not use Hot Start unless
using 450 Ampere Inverter Model.
Arc Time Allows actual arc time up to 9,999.99 hours and weld cycles up to 999,999 to
be accumulated and displayed on the digital display, and can be reset to zero
as required.
Mig Type (Voltage
Correction)
With DVC Voltage Correction On, the unit uses closed-loop feedback from the
17-pin cord or voltage sensing leads to maintain set voltage parameters. With
DVC Voltage Correction Off, feedback from the arc is not used for closed-loop
feedback to maintain voltage parameters. Feedback from the arc is still used
for other functions.
Be sure voltage sensing leads are connected or voltage feedback is available
through the 17-pin receptacle via the welding power source.
Name Feature When using the optional Data Card and turning the name feature on, programs
written to the card can be identified by name, number, job number, etc.
Program Reset By selecting program reset in the memory reset mode, the unit defaults to origi-
nal factory program settings for the program last active. All other program and
setup information remains the same.
Range The interface requires that the voltage and amperage range of the welding
power source be entered. Obtain this information from the welding power
source Owner’s Manual.
Security NOTE: The optional Data Card is required to activate this feature. Is used to
limit what the operator can control. This includes accessing the number of the
program, 1 through 8, and the range of welding parameters within the program.
Software Screen Selection of this function will display the software version of the unit. When
talking with factory service personnel, this number may be required.
System Reset By selecting system reset in the memory reset mode, the unit defaults to origi-
nal factory settings for all programs and all set up excluding System, Arc Time,
and Model Type.
Voltage (Control Feedback) Allows voltage to be monitored at the output terminals by two methods. This
can be selected through the 17-pin cord connection if the welding power source
has a 17-pin receptacle, or through the unit’s external voltage sense lead.
If the 17 Pin setting is used, it is recommended that the voltage sensing termi-
nals on the welding power source be used to monitor arc voltage at the work-
piece.
When using the V. Sense setting, arc voltage feedback is through the voltage
sense leads connected to the feeder. Use this setting when there is more than
50 ft (15 m) of weld cable used.
OM-172 324 Page 6
Arc Start/Volt Sense
Shutdown
When this feature is on, the system immediately shuts down if no arc voltage is
sensed. An error message is displayed. When this feature is off, wire feeds
even when there is no arc voltage sensed.
Wire Feed Mode Allows the selection of inches per minute or meters per minute for wire feed
speed. This mode is also used to select motor type; standard speed, low
speed, or high speed. High speed motor is available as factory option.

A. General
ST-801 077-A
1 Interface Unit
The interface unit is designed for
use in pulse MIG welding (adaptive
or standard), or MIG welding.
The unit is factory-equipped with
eight programs for pulse MIG weld-
ing (see Figure 5-2). The programs
contain parameters that maximize
welding performance for each com-
bination of wire and shielding gas.
The unit also provides memory for
the creation of up to eight MIG pro-
grams (see Section 8).
The weld programs require the user
to enter information specific to the
welding application. This informa-
tion is entered as a part of program
development (see Section 6 for
pulsed MIG information), and dur-
ing setup (see Section 10).

Figure 5-1. Interface Unit
B. Pulse MIG Programs
The eight pulse programs are
shown in the table. Each program
can be used in standard pulse MIG
or adaptive pulse MIG.
In an adaptive pulse MIG program,
the unit manipulates certain weld
variables to hold arc voltage
constant. This feature is described
in Section 7-4.
The factory-set parameters for
each program can be changed to
customize them for an application
(see Section 7).
