OPERATION

4.1. OPERATION

A. WIRE FEEDER COMPATIBILITY

The MultiPower 460 Pulse power source can be used with several types of wire

feeders. The model wire feeder being used will determine the setup method

and operator interface. The position of the REMOTE/PANEL switch deter-

mines the location of the voltage preset and TRIM locations. The wire feed

speed is always set from the wire feeder using the wire speed knob on the

Table 4-1. Wire Feeder Compatibility

feeder control panel. To see the preset wire feed speed, press the PRESET

button on the MultiPower 460 Pulse control panel. Use Table 4-1 to determine

the switch position of operator preference. In most Mig welding applications,

the switch will be in the REMOTE position and the wire feed speed and voltage

will be adjusted from the wire feed front panel.

B. PRESET MODE DIGITAL DISPLAY

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.

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”.

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.

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.

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.

NOTE

The digital volt meter on the MultiPower

front panel reads a maximum of of ap-

proximately 75 Vdc even if the OCV (Open

Circuit Voltage) is higher. The MultiP-

ower 460 has the following OCV"s:

STICK 75 to 80 Vdc

TIG - 38 to 42 Vdc

MIG - 11 to 44 Vdc
