Installation
1 TIG welding machines are fitted with auxiliary power system, so if 15% of the voltage-
la pipe, it still works.
If you use a long wire to the battery voltage drops, it is recommended to increase the
diameter, but if line too long can cause abnormal operation, so choose the correct
length. Ventilation openings to allow free cooling system to operate.
2 Connect the inert gas source. The system includes a gas cylinder, gas regulator and
gas hose, hose clamps should be tightened, to prevent escape of gas or air from
entering.
3 Motor housing is grounded at least 6mm ² conductors, grounding screw on the back
of the machine over to the grounding system.
