6. OPERATION
TIG operation:
Turn on the power on/off switch, power pilot lamp lights, and the fan starts rotating.
Turn on the argon gas switch, adjust the flow rate to the rated standard (you may refer to the
parameter sheet).
Solenoid valve opens after pressing the start-switch of the welding torch, and you will hear the
electric discharge sound of high frequency spark, and there will be argon flow out from the
welding torch’s mouth at the same time. Attention: when first time operation, you should keep
pressing the switch for several seconds till the air in the pipeline has been totally exhausted. When
stop welding, there will still argon flowing out for several seconds, this is specially designed to
ensure enough shield for the welding spot before cooling. So should hold the welding torch on the
welding part for some time after the arc light off.
Set proper current according to the work piece’s thickness and technological requirements.
Keep electrode 2~4 mm away from the work piece, press the welding torch control switch, there
will be high frequency electric discharge between the electrode and work piece. The high
frequency arc starting spark will disappear once the arc is ignited, and the welding is beginning.
