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 areelectricallylive.Incorrectly

installed or improperly grounded equipment is a hazard.

D Do not touch live electrical parts.

D Wear dry, hole-free insulating gloves and body protection.

D Insulate yourself from work and ground using dry insulating mats

or covers big enough to prevent any physical contact with the

work or ground.

D Donotuse AC outputin dampareas,if movementisconfined, orif

there is a danger of falling.

D Use AC output ONLY if required for the welding process.

D If AC output is required, use remote output control if present on

unit.

D Disconnect input power or stop engine before installing or servic-

ing this equipment. Lockout/tagout input power according to

OSHA 29 CFR 1910.147 (see Safety Standards).

D Properly install and ground this equipment according to its Own-

er’s Manual and national, state, and local codes.

D 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.

D When making input connections, attach proper grounding con-

ductor first -- double-check connections.

D Frequently inspect input power cord for damage or bare wiring --

replace cord immediately if damaged -- bare wiring can kill.

D Turn off all equipment when not in use.

D Do not use worn, damaged, undersized, or poorly spliced cables.

D Do not drape cables over your body.

D If earth grounding of the workpiece is required, ground it directly

with a separate cable -- do not use work clamp or work cable.

D Do not touch electrode if you are in contact with the work, ground,

or another electrode from a different machine.

D Useonlywell-maintained equipment.Repairor replacedamaged

parts at once. Maintain unit according to manual.

D Wear a safety harness if working above floor level.

D Keep all panels and covers securely in place.

D Clamp work cable withgood metal-to-metal contact to workpiece

or worktable as near the weld as practical.

D Insulate work clamp when notconnected to workpiece to prevent

contact with any metal object.

D Do not connect more than one electrode or work cable to any

single weld output terminal.

SIGNIFICANT DC VOLTAGE exists after removal of

input power on inverters.

D TurnOffinverter, disconnect input power, and discharge input ca-

pacitors according to instructions in Maintenance Section before

touching any parts.

Welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to your

health.

FUMES AND GASES can be hazardous.

D Keep your head out of the fumes. Do not breathe the fumes.

D If inside, ventilate the area and/or use exhaust at the arc to re-

move welding fumes and gases.

D If ventilation is poor, use an approved air-supplied respirator.

D Read the Material Safety Data Sheets (MSDSs) and the

manufacturer’s instructions for metals, consumables, coatings,

cleaners, and degreasers.

D Workinaconfinedspaceonlyifitiswellventilated,orwhilewear-

ingan air-suppliedrespirator.Alwayshave atrainedwatchperson

nearby. Welding fumes and gases can displace air and lower the

oxygen level causing injury or death. Be sure the breathing air is

safe.

D 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.

D Do not weld on coated metals, such as galvanized, lead, or cad-

mium 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 contain-

ing these elements can give off toxic fumes if welded.

OM-186 989 Page 2

Arc rays from the welding process produce intense

visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin. Sparks fly off from the

weld.

ARC RAYS can burn eyes and skin.

D Weara weldinghelmetfitted witha propershadeof filtertoprotect

your face and eyes when welding or watching (see ANSI Z49.1

and Z87.1 listed in Safety Standards).

D Wear approved safety glasses with side shields under your hel-

met.

D Useprotective screensor barriersto protectothersfrom flashand

glare; warn others not to watch the arc.

D Wearprotectiveclothingmade from durable, flame-resistant ma-

terial (leather and wool) and foot protection.

Welding on closed containers, such as tanks,

drums,orpipes, can causethemto 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 surethe

area is safe before doing any welding.

WELDING can cause fire or explosion.

D Protect yourself and others from flying sparks and hot metal.

D Do not weld where flying sparks can strike flammable material.

D Remove all flammables within 35 ft (10.7 m) of the welding arc. If

this is not possible, tightly cover them with approved covers.

D Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

D Watch for fire, and keep a fire extinguisher nearby.

D Be aware that welding on a ceiling, floor, bulkhead, or partition

can cause fire on the hidden side.

D Do not weld on closed containers such as tanks, drums, orpipes,

unless they are properly prepared according to AWS F4.1 (see

Safety Standards).

D 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.

D Do not use welder to thaw frozen pipes.

D Remove stick electrode from holder or cut offweldingwireatcon-

tact tip when not in use.

D Wear oil-free protective garments such as leather gloves, heavy

shirt, cuffless trousers, high shoes, and a cap.

D Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

FLYING METAL can injure eyes.

D Welding,chipping, wirebrushing,and grinding

cause sparks and flying metal. As welds cool,

they can throw off slag.

D Wear approved safety glasses with side

shields even under your welding helmet.

BUILDUP OF GAS can injure or kill.

D Shut off shielding gas supply when not in use.

D Always ventilate confined spaces or use ap-

proved air-supplied respirator.

1-5. EMF Information

Considerations About Welding And The Effects Of Low Frequency

Electric And Magnetic Fields

Welding current, as it flows through welding cables,will cause electro-

magnetic fields. There has been and still is some concern about such

fields. However, after examining more than 500 studies spanning 17

years of research, a special blue ribbon committee of the National Re-

search Council concluded that: “The body of evidence, in the

committee’s judgment, has not demonstrated that exposure topower-

frequency electric and magnetic fields is a human-health hazard.”

However, studies are still going forth and evidence continues to beex-

amined. Until the final conclusions of the research are reached, you

may wish to minimize your exposure to electromagnetic fields when

welding or cutting.

To reduce magnetic fields in the workplace, use the following proce-

dures:

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 your body.

4. Keep welding power source and cables as far away from opera-

tor as practical.

5. Connect work clamp to workpiece as close to the weld as pos-

sible.

About Pacemakers:

Pacemaker wearers consult your doctor first. If clearedbyyourdoctor,

then following the above procedures is recommended.

3-2. Mode and Voltage Control For Invision 456P

1 Remote 14 Receptacle

Mode Control

The unit defaults to standard MIG

mode. When a suitable external

pulsing control is attached to the

Remote 14 receptacle, the remote

pendant controls whether the unit

is in standard MIG or pulsed MIG

mode. When the pulsing control is

disconnected, the unit returns to

standard MIG operation.

Voltage Control

The unit defaults to Panel control of

output voltage. When a suitable re-

mote voltage control or pulsing

control is attached to the Remote

14 receptacle, the remote device

assumes control of output voltage.

To return to Panel control of volt-

age, disconnect or disable any re-

mote devices that send an input to

pin E.

needed.

2 Voltmeter (see Section 3-5)

3 Ammeter (see Section 3-5)

4 V/A (Voltage/Amperage) Adjust Control

5 Voltage/Amperage Control Switch

For front panel control, place switch in Panel

position and use the V/A Adjust control.

For remote control, make connections to Re-

mote 14 receptacle, and place switch in Re-

mote position. In most modes, remote control

is a percent of the V/A Adjust control setting.

Value selected on V/A Adjust is maximum

available on remote. In the MIG mode, remote

control provides full range of unit output re-

gardless of V/A Adjust control setting.

6 Mode Switch

The Mode switch setting determines both the

process and output On/Off control (see Sec-

tion 3-6). Source of control (panel or remote)

for the amount of output is selected on the V/A

Control switch.

For Air Carbon Arc (CAC-A) cutting and goug-

ing, place switch in the Stick position. For best

results, place Inductance/Dig control in the

maximum position.

7 Inductance/Dig Control

Control adjusts Dig when the Stick or CC

mode is selected on the Mode switch. When

set towards minimum, short-circuit amperage

at low arc voltage is the same as normal weld-

ing amperage.

When set towards maximum, short-circuit am-

perage is increased at low arc voltage to assist

with arc starts as well as reduce sticking while

welding (see volt-ampere curves in Section

2-3).

Select setting best suited for application.

Control adjusts inductance when MIG position

is selected on the Mode switch. Inductance

determines the “wetness” of the weld puddle.

When set towards maximum, “wetness”

(puddle fluidity) increases.

When Pulsed MIG, or one of the TIG modes is

selected, this control is not functional.

3-7. Lift-Arc TIG Procedure For Phoenix 456 CC/CV

With Mode switch in the Lift-Arc

TIG position, start an arc as fol-

lows:

1 TIG Electrode

2 Workpiece

Touch tungsten electrode to work-

piece at weld start point, hold elec-

trode to workpiece for 1-2 sec-

onds, and slowly lift electrode. An

arc will form when electrode is

lifted.

Normal open-circuit voltage is not

present before tungsten electrode

touches workpiece; only a low

sensing voltage is present be-

tween electrode and workpiece.

The solid-state output contactor

does not energize until after elec-

trode is touching workpiece. This

allows electrode to touch work-

piece without overheating, stick-

ing, or getting contaminated.
