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

circuiting, spray transfer (GMAW), flux core (FCAW), Tig (GTAW), and stick

(SMAW) welding and air carbon arc cutting/gouging (CAC-A) applications.

Table 2-1 outlines the electrical and physical specifications.

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 fan will run when the power source is first

powered up and will continue running for 6 minutes, then shut down. The

fan will start again when welding begins and at current levels above 50

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

then shut down automatically.

• Stainless steel frame for environmental durability.

• Durable composite side and top panels will not corrode.

• 100% duty cycle output at 450 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 the

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