J. NON-SYNERGIC PULSE OPERATION

The MultiPower 460 Pulse has the unique ability to Pulse MIG weld in the NON-

SYNERGIC mode. Non-synergic operation means the pulse parameters can

be selected by choosing the WIRE TYPE, WIRE DIAMETER, and presetting

a WIRE FEED SPEED on the MultiPower 460 Pulse panel. The pulse

frequency or arc length (TRIM) is controlled by the TRIM knob. The TRIM knob

is adjustable from the minimum to maximum pulse frequency. By using a

combination of adjusting the wire feed speed on the wire feeder and TRIM

setting on the MultiPower 460 Pulse, the pulse Mig welding arc can be tune in

and stabilized.

The selectable pulse parameters are any combination of WIRE TYPE or WIRE

DIAMETER selected using the PULSE SELECTION switches. Not all combi-

nations will produce acceptable pulse characteristics but by using the pulse

tables provided in this manual, reasonable pulse combinations can be selected

for trial. This will take some trial and error but the added flexibility and

expanded pulse range of the non-synergic mode can be beneficial for many

welding applications.

There are several unique advantages to Non Synergic pulse mig welding. The

Non -Synergic mode of operation permits pulse welding when:

1. A wire feeder without tachometer feedback is used.

2. An "Off the Arc" wire feeder is used

3. The Mig wire type or diameter installed on the wire feeder does not have

a pulse synergic line available..

4. Pulse arc characteristics other than those preprogrammed are desired.

To take advantage of the MultiPower 460 Pulse Non-Synergic mode, it is

necessary to reposition a jumper plug and/or connector in the main control

panel wiring harness. Remove the MultiPower 460 control panel and locate the

jumper plug in the wiring harness in the PC board compartment.

Jumper Plug Installed (Factory Shipped)

Synergic Mode - Pulse circuitry is looking for a 1 volt per 100 inches per minute

signal to determine the pulse parameters required to make the weld.

Jumper Plug Removed and Harness connected

Non-Synergic Mode - The pulse parameters are determined by the position

of the pulse selection switches, the MultiPower 460 Pulse TRIM knob and Wire

Feed Speed preset.
