MIG Welders by Output, Most Powerful First

Output decides how thick a MIG welder handles in one pass. These are the machines in our catalog with the highest maker-stated top amperage, ordered from the most powerful down. By Miller's 1 amp per 0.001 inch rule, 200 amps reaches about 3/16 inch and 250 amps about 1/4 inch.

Peak output means little without duty cycle: a machine rated 30% at 200 amps welds about 3 minutes in each 10 there. Each note gives the maker's duty cycle points and input power; most of these need 240 volts for full output.

Every machine here needs eye protection of at least OSHA's minimum shade, gloves and flame-resistant clothing, and combustibles kept 35 feet away or shielded, per OSHA 1910.252.

The list, rating by rating

Picking between them

Start from the thickest steel you'll weld often and the power you have: Miller's 1 amp per 0.001 inch rule gives the current, and 120-volt circuits cap most machines around 140 amps. Then check duty cycle at that current, not at the peak.

Gas MIG gives cleaner welds indoors; flux-core works outdoors without a bottle. Check the wire sizes the drive rolls take and whether a spool gun is supported if you'll weld aluminium.

When another list fits better

If you only have household power, the 120-volt list fits better.
