●

View actual welding amperage/voltage during welding, and 5 seconds after arc has shutoff.

●

SharpArc ® controls welding arc cone width in pulsed

MIG welding mode.

●

Inductance control customizes weld output characteristics in MIG welding mode.

Exclusive Internal Timers:

●

Tip Saver—Welding output shuts off if tip is shorted to work surface for more than 1 second.

●

Wire Jog Mode

- If trigger is pressed and no arc is detected after 3 seconds, the welding output will be shut off and the unit will go into JOG MODE for feeding wire to the gun.

- Gas Saver — Gas will automatically shutoff after 1 minute when no arc has been detected.

- Wire Saver — Wire drive will automatically shutoff after 2 minutes when no arc has been detected.

Industrial, 4-roll wire drive system features two easy-to-set, scaled, tension adjustments and quick-change reversible drive rolls for .035 and .045 wire.

Welds materials 22 gauge up to 1/2 in thick.

Fan-On-Demand cooling only operates when needed, reducing power consumption and contaminants inside the unit.

Power source is warranted for 3 years, parts and labor.

Original main power rectified parts are warranted for 5 years.

Gun warranted for 90 days, parts and labor.

Built-in pulsed MIG programs (Millermatic 350P only)
