4-15. Preparing Unit For TIG Welding
To prepare unit for TIG welding, 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 3-12).
Turn unit On.
Allow time for unit to complete its start up
cycle.
Set TIG welding process using P3 push
button.

.
If D1 does not display TIG proceed as
follows:
Press P2 setup button. D1 will display STK.
Rotating E2 encoder changes process to
TIG mode.
Purge air from torch gas hose using Torch
Trigger (Manual Purge).
Select trigger mode using P7 push button
(see Section 4-9).
Setting Initial And Final Current
Use E1 to change D1 to IN−A (Initial Cur-
rent).
D2 value is default setting of 20 A (range is
5 A to 400 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 (Final Cur-
rent).
D2 value is default setting of 20 A (range is
5 A to 400 A).
Use E2 to change D2 value.
This parameter allows finishing the welding
process at a lower final amperage setting.

Setting Slope-Up Time
Press P2 to enter SET UP menu.
Use E1 to change D1 to SLUP.
D2 default setting is 0.1 second (range is
0.0 seconds to 10.0 A).
Setting Slope-Down Time
Press P2 to enter SET UP menu.
Use E1 to change D1 to SLDW.
D2 value is default setting of 0.1 second
(range is 0.0 seconds to 10.0 A).
Setting Postflow
Press P2 to enter SET UP menu.
Use E1 to change D1 to POSG.
D2 value is default setting of 5.0 second
(range is 0.0 seconds to 50.0 seconds).
Use E2 to change D2 value.
Setting Cooler Status (see Section 4-3)
.
To prevent damage to water-cooled
torch and components, be sure that
coolant is turned on.
Purge air from torch gas hose using Torch
Trigger (Manual Purge).
Select trigger mode using P7 push button.
