Overview

PrimeWeld MIG285 – Powerful, Portable, and Versatile

The PrimeWeld MIG285 offers both manual and synergetic modes, delivering the power and versatility you need for a wide range of welding tasks. With a maximum output of 285 amps, it can weld materials up to 5/8-inch thick, making it ideal for heavy-duty applications.

Four Welding Processes in One Machine

This all-in-one welder handles MIG, Flux Core, Lift TIG, and Stick welding, giving you unmatched flexibility:

MIG Welding: Perfect for high-speed, efficient welding when time is a priority.
Flux Core: Ideal for outdoor welding where shielding gas isn't available.
Lift TIG: Provides precision and control, with up to 285 amps at a 25% duty cycle.
Stick Welding: Reliable and versatile for fieldwork or quick metal changes.

A Highly Versatile Portable Welding Machine

Weighing under 60 lbs, the PrimeWeld MIG285 is easy to transport around the shop or from job site to job site, making it a highly portable, multi-process welding solution.

Save Fatigue On Your Trigger Finger With 2T/4T Toggle

The innovative 2T/4T toggle system on your PrimeWeld MIG285 allows you to easily change from a traditional two-touch trigger to a four-touch.

The two-touch system functions as you’re used to, pull the trigger to start welding and release to stop the weld.

In the four-touch mode once the weld has been started you can release the trigger and continue welding until the trigger is activated again or the welding arc is broken to stop the welding arc.
