SECTION 2 DESCRIPTION

The MultiPower 460 Pulse is a multi-process power source designed for Mig short circuiting, spray and pulse spray transfer

(GMAW), ﬂux cored (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 cored 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. It will continue running for

6 minutes and 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 450 amps.

• Designed for “Oﬀ the Arc” wire feeders.

B. Volt - Ampere Characteristics

The curves shown in Figure 2-1 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.
