1. The green wire inside the cord is connected to

the grounding system in the welder. The green

wire in the cord must be the only wire connected

to the welder’s grounding system and must never

be attached to an electrically “live” terminal.

Never leave the grounding wire disconnected

or modify the Power Cord Plug in any way.

2. Make sure the tool is connected to an outlet having

the same configuration as the plug. If the tool must

be reconnected for use on a different type of electric

circuit, the reconnection should be made by qualified

service personnel; and after reconnection, the tool

should comply with all local codes and ordinances.

2. The metal work bench must be properly grounded

in accordance with all relevant electrical codes

and standards before operation. Have the work

bench grounded by a qualified electrician

if you are not qualified to do so.

3. To ground the work bench, connect a #12 AWG

grounding wire (not included) from the work

bench to a grounding rod (not included).

The grounding rod must be an earth-driven

copper or brass rod (electrode) which can

adequately ground the work bench.

Operation may be resumed on a regular basis

of Torch. (Pulling it from rear will damage

Collet and create burrs on Electrode).

• DC TIG Welding is used to weld

mild steel and stainless steel using

a TIG Rod and shielding gas.

• AC TIG Welding is used to weld aluminum

using a TIG Rod and shielding gas.

• DC Stick Welding is used to weld

mild steel and stainless steel using a

Stick Electrode without shielding gas.

Good welding takes a degree of skill and experience.

Practice a few sample welds on scrap before

welding your first project. Additional practice

periods are recommended whenever you weld:

• a different thickness of material

• a different type of material

• a different type of connection

• using a different process

1. Clean the weld surfaces thoroughly with

a wire brush or angle grinder; there must

be no rust, paint, oil, or other materials on

the weld surfaces, only bare metal.

2. Use clamps (not included) to hold the workpieces

in position so that you can concentrate on

proper welding technique. The distance

(if any) between the two workpieces must be

controlled properly to allow the weld to hold

both sides securely while allowing the weld

to penetrate fully into the joint. The edges of

thicker workpieces may need to be chamfered

(or beveled) to allow proper weld penetration.

NOTICE: When welding equipment on a vehicle,

disconnect the vehicle battery power from both the

positive connection and the ground before welding.

This prevents damage to some vehicle electrical

systems and electronics due to the high voltage

and high frequency bursts common in welding.

EXACR6-% TIG welding is a complicated process,

requiring experience and skill to achieve

successful results. Training beyond the scope of

this manual is required to TIG weld properly.

1. Open gas cylinder’s valve all the way.

2. Set Flow Gauge to SCFH value indicated

on Settings Chart on top of Welder.

3. Turn the Power Switch to the OFF position, then

plug the Welder into a properly grounded, GFCI

protected, 120 VAC (20 amp rated) outlet or

240VAC receptacle that matches the plug.

The circuit must be equipped with delayed

action-type circuit breaker or fuses.

4. Set TIG Torch down on nonconductive,

nonflammable surface well away

from any grounded objects.

5. Turn the Power Switch ON.

5. WX?A%<GXT%K The number of seconds (0.3-20)

1. @DW6;@V6%K%Set amperage according to

Settings Chart on top of Welder. Set to high end of

amperage range.

For example: Range is 50-120A,

set amperage to 120A.

EXA6- Amperage Settings are

approximate. Adjust as necessary.

2. W;6%<GXT%K The number of seconds (0.3 - 20) that

gas will flow once the pedal is pushed. The arc will

not started for that pre-set time, but gas will flow.

Once the pre-set time expires, the arc will start.

3. WX?A%<GXT%K The number of seconds (0.3-20)

that gas will flow once the pedal is released.

When machine is set in AUT mode, the gas flow

will automatically adjust to the factory default

setting based on the pre-set welding amperage.

4. WFG?6%K Turn Pulse Frequency ON and OFF.

5. S@R[V;XFEU%@DW?%K during the pulsing

cycle, the amperage will rotate between a

Peak Amperage (pre-set) and a Background

Amperage. The lower the background amperage

is set to reduces the overall heat input.

6. W6@[%ACD6%K The percentage of time in each cycle

spent at the peak amperage (pre-set amperage).

Increasing peak time increases time spent at the

peak amperage, which increases overall heat input.

7. WFG?6%<;6gF6ERQ%K Set Pulses Per Second.

Pulse welding reduces heat input to minimize

distortion and allows for faster travel speeds.

1. Hold TIG Torch in one gloved hand and

the TIG Rod in other gloved hand.

2. Specific Welding Techniques:

B"3.%<(*H'*84>%?$,($%

• Hold Torch away from the workpiece

the same distance as 1 to 1.5 times the

diameter of the Tungsten Electrode.

• Press Foot Pedal down slowly until arc

ignites. Then, press Foot Pedal down all

the way to reach maximum amperage. Let

up on Foot Pedal to lower amperage.

W'7#*%T*79"83

• After arc is ignited, Welder will pulse between

Peak Amperage and Background Current.

EXA6- Maintain a constant distance between the

Tungsten Electrode and the workpiece: between

1 and 1.5 times the diameter of the Electrode.

3. When welding puddle is hot enough, tilt torch

backward about 10-15 degrees from vertical and

move it back slightly. Add TIG Rod material as

needed to the front end of the weld puddle.

EXA6- When welding aluminum, if black spots

appear in the weld puddle, reduce AC Balance.

4. Alternate between pushing the torch/weld

puddle and adding the TIG Rod material.

EXA6- Back the TIG Rod off each time the Electrode

is advanced, but do not remove it from the gas shield.

This prevents oxidation from contaminating the weld.

5. When finished welding, release the Foot Pedal, but

keep Torch on weld puddle until gas flow ends.

6. Set TIG Torch down on nonconductive,

nonflammable surface away from

any grounded objects.

7. Turn the Power Switch off.

8. To prevent accidents, after use:

• Allow Welder to cool down.

• Unplug Welder’s power cord from outlet.

• Remove Ground Clamp from workpiece or table.

• Disconnect TIG Torch, Ground

and Foot Pedal Cables.

• Close gas cylinder’s valve securely,

remove regulator and replace cap.

• Disconnect Gas Hose from Welder.

• Store and secure gas cylinder.

• Clean, then store Welder and its accessories

indoors out of children’s reach.

1. Turn the Power Switch to the OFF position, then

plug the Welder into a properly grounded GFCI

protected, 120 VAC (20 amp rated) or 240VAC

The circuit must be equipped with delayed

action-type circuit breaker or fuses.

2. Set Electrode Holder down on
