F. TIG WELDING

When the PROCESS switch is placed in the TIG position, the Multipower

460PULSE is automatically set for CC (constant current) welding using the ESAB

Touch TIG starting method. The voltage and current at the output lugs is

maintained at low values until the tungsten electrode is shorted to the workpiece.

Step 1. Be sure to set the polarity to DCEN (Electrode Negative) by connecting

the Tig torch to the negative terminal lug on the front of the power source.

Step 2. Place the WELD PROCESS switch in the TIG position.

Step 3. Place the PANEL/REMOTE switch in the PANEL position.

Step 4. Place MIG MODE PULSE switch in the STANDARD position.

Step 5. While depressing the PRESET button, turn the VOLTAGE/CURRENT

knob to the desired weld current as displayed on the top digital display

window.

Step 6. Set the shielding gas flow rate to 20 cfh by adjusting the control knob on

the flowmeter.

Step 7. Touch the tungsten electrode to the workpiece momentarily then lift

1/16" off the workpiece to establish the welding arc. Trim the weld

current as desired by turning the VOLTAGE/CURRENT knob.

NOTE:

If a Foot Control or Remote Hand Control

is used for continuous current control,

place the PANEL/REMOTE switch in the

PANEL POSITION and set the Panel

Curent knob to the maximum desired

weld current. The remote device will then

control the current between minimum and

the maximum setting preset.

G. STICK WELDING

When the PROCESS switch is placed in the STICK position, the Multipower

460PULSE establishes open circuit voltage (OCV) and output power is

immediately available for welding. This means that the STICK electrode holder

is “HOT”, and an arc will strike when the electrode comes in contact with the

workpiece or any other object at ground potential.
