Invision™350 MPa System MIG Welding

Power Source

Issued Nov. 2007 • Index No. DC/23.5

Lightweight, aerospace-grade aluminum

case offers protection with the benefit of

reduced weight.

SharpArc™technology changes welding arc

characteristics in Pulsed MIG welding mode.

Auto-Line™Power Management

Technology allows for any input voltage

hook-up (208 – 575 V) with no manual

linking required, providing convenience

in any job setting. Ideal solution for dirty

or unreliable input power.

Easy setup for MIG and Pulsed MIG

applications.

Inverter arc control technology provides

greater puddle control for outstanding MIG

weld performance.

Fan-On-Demand™cooling system

operates only when needed, reducing

noise, energy use and the amount of

contaminants pulled through machine.

The Power of Blue®

.

Dynamic Pulsed MIG — highly-engineered

pulse programs default to give a tight

productive pulse arc. The operator can

fine tune the arc if desired.

Quick

Specs

Line voltage compensation keeps welding

output constant even if input power varies

by +/-10%. XMT 350 models further expand

line voltage compensation on 460 VAC to

an amazing +37%, -59%.

Large, dual digital meters are easy to

view and are presettable to ease setting

weld output.

Invision 350 MPa System

Add the new S-74 MPa feeder for a

package that gives you the benefit of

Synergic-Pulsed MIG. As you increase/

decrease the wire feed speed, the pulse

parameters increase/decrease matching

the right amount of power output to

the wire speed.

efficiency is 87.24%!

350 A of welding output at 60% duty cycle

with superior low-end performance.

Power factor of .95 enables smaller

fuses/breakers and primary wiring. Primary

amperage draw at rated output is 25% less

than the competition.

Additional Features

SharpArc™

Changes welding arc characteristics in

Pulsed MIG (GMAW-P) welding mode.

If a gas is used other than what is listed

on the Pulsed MIG welding program

chart (below left), the SharpArc™can be

adjusted to help customize your arc to the

gas being used.

Lower SharpArc™settings widen the arc

cone, increase puddle fluidity and flattens

the weld bead.

Auto Remote Sense™

Enables unit to automatically use remote

control if connected to remote control

receptacle.

Dinse International-style weld disconnects

Provide high-quality weld cable connections.

Dinse and Tweco connectors are available.

When Dinse connectors are specified, two

connectors are supplied with the unit.

Optional 115 VAC auxiliary power

Provides 10 amps of circuit-breaker-

protected power for water circulators, etc.

MPa

MPa: M (MIG), P (Pulse), a (Advanced

Arc Control). Advanced arc control

enables an improved pulse welding arc.

The operator has more control over puddle

and bead characteristics using SharpArc™

.

In addition, the unit provides a more robust

and stable arc at very low arc length, reducing

heat input, and providing the ability to weld

on a wider range of material thickness.

Synergic pulsing is available only with the

S-74 MPa dedicated wire feeder.

What are some benefits of

Synergic-Pulsed MIG?

1. Easier to set up

2. No more changing wire speed, and

then having to go back to reset the

welding output.

The Invision 350 MPa has built-in dynamic Pulsed MIG capabilities. See the table below for the wide

range of Pulsed MIG (GMAW-P) welding applications the Invision 350 MPa can handle.

The Invision™350 MPa and S-74 MPa combine for a synergic system that simplifies and

improves MIG and Pulsed MIG welding applications for industrial manufacturing.

S-74 MPa Single Feeder Features

Dual tension control adds flexibil ity

for the operator to fine-tune the

pressure on the wire independently

when feeding a variety of wires.

Tool-less rotatable drive assem bly

allows operator to rotate the drive

housing, eliminating severe bends in the

wire feed path which reduce gun liner

life. Also aids in feeding difficult wires.
