SET-UP, OPERATION & TROUBLSHOOTING

Torch & earth clamp checklist:
Check welding cable machine connections are twist-locked in place and gas fittings are
secure; otherwise there may be malfunction such as ignition spark, gas leakage, and
unstable arc.
Check that there is enough shield gas in the cylinder and that regulator is set correctly, you
can test the electromagnetic gas valve through the switch on the front panel.
Do not aim torch at your hand or anywhere on your body. When you press the torch switch,
the arc is ignited with a high-frequency, high-voltage spark. The ignition spark can burns.
The shield gas flow rate is set according to the welding power used in the job. Turn the
regulation screw to adjust to the desired gas flow required for the application.
The HF ignition works better if you keep
3mm (1/8”) distance from the work-piece to the
tungsten electrode during the ignition.
Note: When the AC output is selected, the settings are as same as the above, but output
polarity changes.
