Master of one.
What I mean by this is yes it is a Multi process machine but the real focus is one MIG. Reading the manual confirms this with most of the information dedicated to the MIG process. I've owned this welder for over 6 years now and mainly used it as a MIG welder, recently I tried running it as a stick welder and here's what I found. My biggest grip is when MMA welding (ARC) you have no idea what AMPS you have the machine set too. All it displays is the open circuit voltage until you strike an arc. Not very useful when welding solo unless you want to risk arc eye. I resorted to filming the display while welding on a test piece to get it set.
A chart in the manual with approximate current knob to amps would have been real useful. I haven't tried TIG mode with it but the above would be true with this process as well.
