For as much as I’ve enjoyed leaving MIG welding behind me in favor of TIG, I have to say I’m intrigued with pulsed MIG. It appears that many automakers are requiring their new vehicles be repaired with more specific techniques than ever, including pulsed, double pulsed, CuSi3, and even pulsed CuSi3. The MIG brazing requirement appears to be an accepted alternative when you can’t repair via the original Squeeze Resistance Spot Welds.

Anyways, I was wondering how it might fit into our type of work or if anybody uses it for that. Does pulsed MIG with its lower temps more closely resemble the good properties of TIG (“softer” less-brittle welds)? Regarding the ease of MIG brazing, does that open things up to it being abused and used everywhere in repairs (including high stress/flex places where it might not belong)?

I still dislike MIG for the whole “dirty” factor compared to TIG, but the sale prices from HTP on what always seems to be regarded as one of the premium Pulse MIG units always makes me think twice lol.
