electrode to ground before adjusting or troubleshooting the unit.

Possible Causes

The duty cycle limit of the

machine has been exceeded.

The input voltage is too

high or too low.

The TIG torch trigger is

stuck or is triggered when

turning on the machine.

Ground clamp and TIG torch or

electrode holder are in contact.

IMPORTANT!

Fault Code Table

Allow the machine to cool down. Keep the

machine plugged in and turned on to allow

the fan to continue to run. Reduce duration or

frequency of welding periods. Refer to Duty Cycle

(Duration of Use) on page 15. Check for any

obstructions blocking air flow into the machine and

ensure proper clearance between any obstacles

and the vents on all sides of the machine.

Verify the voltage at the outlet and

the connection to the outlet.

Turn OFF the machine and ensure

the TIG torch trigger is reset.

Check the connection of the ground clamp

and TIG torch or electrode holder to make

sure they are not in contact. Lift the electrode

holder or TIG torch up to take the electrode

away from the workpiece and restart arc.

Page 21: Welding Tips
Welding Tips A good way to test welding technique is to examine a weld’s appearance after it has cooled and the slag has been removed (for Stick welds). Then, better welding can be learned by adjusting your weld technique to remedy any problems found. NOTICE: TIG welding is a complicated process, requiring experience and skill to achieve successful results.
