Multi-Process Welders by Output

A multi-process welder puts several processes in one inverter, which suits a home shop that wants to MIG, stick and try TIG without three machines. These are ordered by the maker's top output, highest first.

Read the process list closely: TIG on most multi-process machines is DC lift-arc (no aluminium), and the TIG torch or spool gun is often sold separately. Each note quotes the maker's process list.

Most multi-process machines are inverters, light enough to carry, and many run on both 120 and 240 volts.

The list, rating by rating

Picking between them

List the processes you'll really use, then confirm each is in the maker's list with the torch or gun included. Check input voltage and output on each input, and duty cycle at your amps.

If TIG on aluminium matters, look for AC TIG or a supported spool gun; DC lift-arc TIG won't do it.

When another list fits better

If you'll only ever MIG, a dedicated MIG welder may give more for the money.
