I Bought this machine purely for the MIG with use of shielding gas feature & with capability of using 110v/220v. This allows the machine to be much more versatile if you are mobile with it as well. I have tested the welds with gas using 110v and got great penetration up to 1/4" thickness. When applying 220v the penetration was good up to 3/8" easily. I did not experience any pulsing with this machine while using it like my other smaller machines did, and I get to us a 11kg spool as well. The flux core wire supplied I tested out by cutting out and replacing the flex pipe on my Honda, and to my surprise, it welded up very easily. So much so that the whole job only took me 30 minutes in my driveway. I have not found the greatest use for the matchstick TIG that was supplied yet. The MMA/SMAW did well with 7018, which is mostly what I use when using stick. So, overall, I am VERY pleased with this machine!
