The MM251 is the only way to go. I love mine!!! I have welded .060” cheap truck tool boxes, too ½” cast aluminum trap housings. Works like a dream.

The 15A spool gun for the MM251 is a quality tool. The 3035 spool gun is a toy compared to the 15A. Just my personal opinion!!

That’s a great price on BullDog ‘s unit.
