To select TIG welding process, proceed as follows:

Follow safety precautions according to Section 1.

Prepare unit according Section 3.

Connect torch to the WORK connector 3 and the gas pipe to the gas connector 5.

Using a cable with a proper adapter, con- nect work clamp cable to the MIG gun con- nector.

If using a water-cooled torch, connect input coolant hose to blue quick connect fitting and return coolant hose to red quick con- nect fitting.

.Check coolant level after attaching

torch coolant hoses and running cool- er. Be sure coolant appears in upper half of indicator. Add coolant if neces- sary (see Section 3-9).

Setting Initial And Final Amperage (only in MENU FULL)

To set initial and final amperage, proceed as follows:

Press P2 to enter SET UP menu.

Select MENU FULL on D1 and D2 (see Section 4-9).

Use E1 to change D1 to IN−A.

D2 value is default setting of 20 A (range is 0 A to 350 A).

Use E2 to change D2 value.

This parameter allows starting the welding process at a lower initial amperage setting.

Use E1 to change D1 to FI−A.

D2 value is default setting of 20 A (range is 0 A to 350 A).

Use E2 to change D2 value.

This parameter allows finishing the welding process at a lower final amperage setting.

Setting Postflow (only in MENU FULL)

Select MENU FULL on D1 and D2 (see Section 4-9).

Use E1 to change D1 to POSG.

D2 value is default setting of 0.1 second (range is 0.0 seconds to 10.0 seconds).
