Highest output in it's class (250 A at 28 VDC).

Weld longer on high-end applications.

Large, Digital front panel with built-in digital timers menu

Enables operator to preset voltage and wire feed speed. Standard run-in, pre/postflow, burnback, spot/delay (stitch) timer menu.

Auto Gun Detect

Allows operator to simply pull trigger on MIG gun, spool gun or push/pull gun. Automatically detects and recalls the voltage, wire feed speed and timer of the active gun.

Push-pull gun direct connection.

Now directly connects your push-pull gun, no extra module required.

Line voltage compensation

Keeps power constant even if power input varies by 10%

Active Arc Stabilizer

Minimizes weld cleanup, and provides excellent starts proven superior to the competition

EZ-Access consumable compartment and parameter chart.

Set weld parameters right the first time with convenient flip-down compartment that provides fast acess to parameter chart and consumables.

Standard Fully Loaded Features

EZ-Change Low Cynder Rack

Operators no longer need to lift cylinders. Cynders now easily roll on and off our EZ-Change Low Cynder Rack.

Angled Wire Drive

Angled industrial aluminum dual-gear drive system significantly improves wire feeding and runs large spools of wire. Allows quick change of drive rolls without tools. Drive roll storage - no more lost drive rolls, extra drive rolls are conveniently stored next to drive motor. Operators no longer bump into and bend MIG gun and gunner.

Dual Front Handles

Split handle with rubber grips designed to move machine easily and allow work lead and MIG gun to be stored independently. Handles provide protection for front panel and MIG gun during transportation.

EZ-Access Consumable Compartment and Parameter Chart

Convenient flip-down compartment holds parameter chart and storage for consumables.

Auto Gun Detect

Simply pull the trigger for either the MIG, spool gun or any Miller push-ppl gun. The Millermatic 252 automatically recalls voltage, wire feed speed and timer of the active gun Reduces setup time!
