C. Tig Welding (Lift Start Tig)

When the PROCESS switch is placed in the LIFT START TIG position, the MultiPower 460 Pulse is automatically set for CC

(constant current) welding using the ESAB Lift Start TIG starting method. The voltage and current at the output terminals

are maintained at low values until the electrode is shorted to the workpiece then “lifted” to create the welding arc.

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.

Place the WELD PROCESS switch in the LIFT START TIG position.

Place the PANEL/REMOTE switch in the PANEL position.

Place STANDARD/MIG PULSE switch in the STANDARD position.

While depressing the PRESET button, turn the VOLTAGE/CURRENT knob to the desired weld current as displayed

on the top digital display window.

Set the shielding gas ﬂow rate to a desired ﬂow by adjusting the adjustment knob on the ﬂowmeter. (20 cfh is

typically recommended)

Touch the tungsten electrode to the workpiece momentarily then lift the electrode 1/16" oﬀ the workpiece to

establish the welding arc. Trim the weld current as desired by turning the VOLTAGE/CURRENT knob.

SECTION 4 OPERATION

NOTE

When using a remote current device with the MP-460 Pulse, the STANDARD/MIG PULSE switch must be in

the STANDARD position for proportional current control. Set the current knob on the MP-460 Pulse front

panel to the maximum desired weld current using the procedure above. The remote device will then

control the current proportionally between the minimum current setting of 5 amps and maximum set on

the MP-460 front panel. The maximum Tig welding current is 525 amps.

If the MP-460 PANEL/REMOTE switch is left in the REMOTE position while using a remote control option

device, the current range will be full scale or 10 to 400 amps on the remote device. Adjustment of the

maximum current on the MP-460 Pulse front panel is defeated.

When the WELD PROCESS switch is moved to the TIG or STICK position,

electrode becomes electrically “HOT”. Do not allow the electrode to

contact ground potential until you are ready to make a weld.
