The MultiPower 460 Pulse is a multi-process power source designed for Mig

short circuiting, spray and pulse spray transfer (GMAW), flux core (FCAW),

Tig (GTAW), and stick (SMAW) welding and air carbon arc cutting/gouging

(CAC-A) applications. Table 1-1 outlines the electrical and physical specifi-

cations.

A. POWER SOURCE

The power source is a constant current (CC) and constant voltage (CV), three

phase, secondary chopper dc design with solid state contactor and control

circuitry. It provides the volt-ampere characteristics desired for conventional

MIG and flux core arc welding in the CV (constant voltage) mode or stick welding,

Tig (GTAW) and arc gouging in the CC (constant current) mode.

Features

• Auto Fan - The MultiPower 460 Pulse fan will run when the power source

is first powered up and will running for 6 minutes then shut down. The

fan will start again when welding begins and is at a current level above

50 amps. The fan will remain running for 6 minutes after welding stops

and then shut down automatically.

• Stainless steel frame for envirornmental durability.

• Durable composite side and top panels will not corrode.

• 100% duty cycle output at 460 amps.

• Compatible with all ESAB 42 vac wire feeders.

B. VOLT - AMPERE CHARACTERISTICS

The curves shown in Figure 2-2 represent the static volt-ampere characteristics

for the power source. The slant of these curves is referred to as the "slope"

and is generally defined as the voltage drop per 100 amperes of current use.

These curves show the output voltage available at any given output current from

theminimum to the maximum setting of the voltage/current control.
