OPERATION

3. SHIELDING GASES

Table 4-2 lists the types of shielding gas mixtures that can be used with the

MultiPower 460 Pulse. The wire burn-off rate and synergic operation can vary

with changes in shielding gas. The TRIM knob is used to compensate for small

changes in shield gas composition.

4. SYNERGIC PULSE OPERATION

The MultiPower 460 Pulse can be converted to Pulse Mig synergic operation

by adding optional components. Synergic pulsed Mig welding means that

pulse parameters, such as pulse height, pulse width, background current and

pulse frequency, are automatically preset based on the WIRE TYPE, WIRE

DIAMETER and wire feed speed selected. These parameters are further

adjusted by the MultiPower 460 Pulse as the wire feed speed is changed by

the operator. If a TRIM adjustment has been made to the synergic

parameters, this offset will automatically track when wire speed changes.

Contact your local ESAB Sales Representative for more information.

5. 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 parmeters

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

range and

does not track with changes in wire feed speed. A change in wire

feed speed will require a re-adjustment of the arc length TRIM.

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

Non -Synergic mode of operation permits pulse welding when:

a. A wire feeder without tachometer feedback is used.

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

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

have a pulse synergic line available.

d. Pulse arc characteristics other than those preprogrammed are

desired.

By using a combination of wire feed speed and front panel TRIM setting, the

pulse Mig welding arc can be fine tuned in and stabilized. The selectable

pulse parameters are any combination of WIRE TYPE or WIRE DIAMETER

selected using the PULSE SELECTION switches. Not all combinations will

produce acceptable pulse characteristics but, in many cases, resonable

pulse arc welding stability can be achieved using WIRE TYPE, WIRE

DIAMETER, WFS, TRIM and shield gas combinations selected. This will

take some trial and error but the added flexibility and expanded pulse range

of the non-synergic mode can be beneficial for specialtiy or rare welding

applications.

Jumper Plug Installed (requires jumper change)

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.
