MPa: M (MIG), P (Pulsed), a (Advanced Arc Control). Built-in Pulsed MIG using advanced arc control offers a robust and stable pulse arc even at short arc lengths. Also eliminates pulsing pendants and cables that could potentialy get damaged or lost.

Built-in Pulsed MIG programs provide optimal parameters for steel, metal core, stainless, aluminum, nickel, silicon bronze, and coppernickel wires. Operator just dials in wire and gas type. As easy to use as traditional MIG - programming virtually elimnates Pulsed MIG learning curve for experienced MIG operators.


Invision MPa System - Add the new S-74 MPa wire feeder to receive the benefits of a synergic system. As you increase or decrease the wire feed speed, the pulse parameters automatically match the right amount of power output to the wire feed speed.

Sharp Arc™ controls the arc in Pulsed MIG mode and gives total control over the arc cone shape, puddle fluidity, and bead profile. Sharp Arc can adjust from a wider arc cone with increased fluidity and flatter bead profile, to a stiffer puddle with narrower bead.

AutoLine™ - Patented Miller technology allows for any input voltage hookup (208-575 V), single- or three-phase, 50 or 60 Hz, with no manual linking.

Exceptional electrical efficiency - At 400 amps, efficiency is 87.24%!

Simple user interface allows set-up as easy as 1-2-3.

Microprocessor-based Technology™ allows process parameter storage to be retained between power down and power up and also between program changes.

Dual digital meters for quick and easy viewing.

Large setup screen to choose pulse welding mode.

Pulsed spray transfer helps reduce spatter and fume levels.

Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.

Wind Tunnel Technolgy™ protects electrical components and PC boards from contamination, significantly improving reliability.

14-pin select remote control allows "plug and play" convenience. Makes set-up time quicker.

Protective cover for front control panel protects controls from damage in rough conditions.

Optional 10 amp, 115 VAC auxiliary power available.

Power cable included.

LVC™ Line Voltage Compensation
keeps output of the power source constant regardless of fluctuation in input power ± 10%.
