OPERATION

Set Up for TlG Welding (GTAW)
WARNING: TIG TORCH IS ALWAYS LIVE (ELECTRICALLY HOT). Use caution and ensure the TIG torch is not in contact
with or close to a conductive or grounded material.
Note: REMOVE ALL THE COLLECTION FROM THE POSITIVE(+) , NEGATIVE(-) OUTPUT RECEPTACLE, AND TORCH
CONNECTOR.
Connect the TIG torch electric connector to the welder's Negative (-) Output Receptacle.
Ÿ
Connect the TIG torch gas connector to the welder's Torch Connector.
Ÿ
Plug the 5-pin torch control switch cable into to Trigger Connector Receptacle.
Ÿ
Connect the work clamp to the welder's Positive(+)Output Receptacle, ensure it has good contact with the workpiece on a clean,
Ÿ
bare metal surface free of rust, paint, or coating.
Set the tungsten electrode to stick out approximately 1/4" inch from the end face of the gas cup. Please use the correct size and
Ÿ
type of tungsten electrode in your project. The small size of tungsten can handle the low welding current. The tungsten electrode
requires a sharpened tip in DC welding and a round tip in AC welding.
Attach the work clamp to the workpiece that needs welding.
Ÿ
Put the TIG torch away from all conductive materials.
Ÿ
Install the gas hose into the Inlet for Argon Gas and connect to the gas pressure regulator (100% Argon only).
Ÿ
Open the gas cylinder valve and adjust the gas pressure regulator to the correct flow rate(Recommend 20-35CFH).
Ÿ
Plug the power cable into a suitable power outlet, recommend NEMA6-50R.
Ÿ
Turn on the power source and select AC TIG/DC TIG/DC PULSE TIG/AC PULSE TIG process with the Welding Process
Ÿ
Selection.
Press the Value Knob to set parameters and rotate the knob to adjust the values.
Ÿ
Place the electrode to the workpiece and trigger the torch control switch to initiate the welding arc with HF
Ÿ
technique.
REMEMBER TO CLOSE THE VALVE ON THE GAS CYLINDER IMMEDIATELY
AFTER ALL WELDING IS COMPLETED.
Welding Tips:
• Always weld clean, dry and well-prepared material.
• Hold the torch at a 45° angle to the workpiece with gas cup about 1/2" from the surface.
• Move the torch smoothly and steadily as you weld.
• Avoid welding in very drafty areas. A draft will fail the shielding gas protection and lead to a porosity defect.
• Keep wire and liner clean. Do not use rusty or dirty wire.
• Please don't bend or kink the welding torch cable.
