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).
