Flexibility and simplicity make this the most

popular model. It has the core multiprocess

capabilities along with the flexibility of a

14-pin for spool guns, feeders, and remote

controls.

Built-in pulse programs for manufacturing and fabrication applications that have benefits for

standard steels, high-strength steels and aluminium.

Pulse programs provide reduced heat affected zone,

weld in all positions, great for thick-to-thin metal, good

gap filling ability and faster travel speeds and deposition.

SharpArc® controls the arc in pulsed MIG mode and

gives total control over the arc cone shape, puddle

fluidity and bead profile.

Additional features when using a 70 Series MPa Plus feeder or XR-AlumaFeed® feeder.

Synergic pulsed MIG.

As you increase/

decrease the wire

feed speed, the pulse

parameters increase/

decrease, matching

the right amount of

power output to match

the wire speed,

eliminating the

need to make

additional

adjustments.

Profile Pulse™ provides

TIG appearance with

MIG simplicity and

productivity. Achieve

“stacked dimes” without gun manipulation. Profile Pulse

frequency can be changed to increase or decrease the

spacing between the ripple pattern to achieve the

desired weld appearance.

Added capabilities with Insight Core.™ When using an

MPa Plus feeder, wire deposition is added to the Insight

Core capabilities.

*Optional 115-volt auxiliary power provides 10 amps of circuit-breaker protected power for coolant systems, etc.

**Duty cycle rating below achieved with 6-gauge input power cord (8-gauge cord supplied with unit).
