SECTION 4 OPERATION

Never operate the power source with the covers removed. In addition

to the safety hazards, improper cooling may cause damage to the

components. Keep side panels and top closed when unit is energized.

Welding helmet, gloves, and other personal protection should always

be worn when welding.

CAUTION

NOTE

The digital volt meter on the MultiPower front panel reads a maximum of approximately 75 VDC even if

the OCV (Open Circuit Voltage) is higher. The MultiPower 460 has the following OCV"s:

STICK - 75 to 80 Vdc,

TIG - 38 to 42 Vdc

MIG - 11 to 44 Vdc.

2. Preset Tig And Stick Welding

In the TIG and STICK process mode, you must depress and "HOLD" the PRESET button while presetting the welding current

in the top display. Releasing the preset button causes the display to return to zero. Once welding begins, the display will

show average welding current and volts in the top and bottom display, respectively. After welding stops, the current display

will again return to zero. There is no “HOLD” circuit for the display meters when using the TIG and STICK process modes.

B. Digital Display Preset Mode

The digital displays located on the left side of the control panel are multifunctional depending on the welding process

being used. The MultiPower 460 Pulse digital display meters permit preset of the wire feed speed on wire feeders without

digital displays.

NOTE

The digital wire feed speed meter on the MultiPower front panel reads a maximum of 760 ipm. Some

wire feeders have speed ranges that exceed this maximum limit of the digital meter. Wire feed speeds

above 760 ipm will be displayed at 760 ipm.

1. Preset Mig Welding

In the MIG process mode, the digital displays will read preset wire feed speed in inches per minute and preset arc volts when

the PRESET button is pressed. Once welding begins, the displays will show average welding current and volts in the top and

bottom display, respectively. The displays have a “HOLD” circuit that retains the welding conditions. After welding stops, the

display will continue to show the last average welding current and voltage sampled for 10 seconds, then returns to “0”.

4.0. Operation

A. Wire Feeder Compatibility

The MultiPower 460 Pulse power source is designed for use with “Oﬀ the Arc” or “Voltage Controlled” wire feeders. These

types of wire feeders can be operated in either the CV (MIG) or CC (Stick) mode. The wire feed speed is always controlled

from the wire feeder using the wire speed knob on the feeder control panel. The MP-460 Pulse can output either CV or CC

power. Use the PANEL/REMOTE switch in the PANEL position to set the power source open circuit voltage (OCV) for the CV

mode or the welding current for the CC mode. Use the REMOTE position when using a remote control device.
