This gun does not feel cheap, but MIG welding aluminum is much different from steel or TIG welding aluminum.
The gun is a mid price point for Miller products. My brother has a gun that costs easily twice as much, for his Miller 252. I thought this gun might feel cheap or like a toy, but it looks well made and feels nice in the hands. The tips are just a little different than the Miller m-150 (or other miller guns) MIG tips. Why didn't they just make the spool gun use the same tips so we only have to stock one part number for each size wire? I played with this gun and the Miller 211 inverter for half an hour, on aluminum. I previously used my brothers spoolgun for about half an hour. It has a real learning curve and I have used MIG and TIG for 15 years. Other spoolgun users say that the right settings and technique are critical with aluminum and a spoolgun. Tig will move at a very slow pace if you want, or you can speed it up a little. Mig is 5x faster than tig, and the spoolgun feels like it needs to be pushed 20x faster than MIG. Hopefully I will find more time to use it and get it down pat so I can utilize the speed over TIG, which saves gas and electricity, along with time.
ProsFeels well made even though it is half the cost of other Miller guns. Tips are not as expensive as the tips for the high end Miller spool guns (according to what my brother claims to spend on them). I think the cable is 25' and it seems like a mile compared to a 10' mig gun.
ConsTips do not match the MIG gun tips, and yet they look almost the same. Using a spool gun for welding aluminum takes precise settings and technique compared to Mig welding steel and it moves like lightning compared to TIG welding, so it is not an instant fix for aluminum welding needs................but I knew that when I bought it and hope to learn to make beads that are strong and half decent looking while saving time over using TIG.
