Looks great Josh, 175 amp is plenty. I'm going to say you're running co2 shielding gas with that hard wire. My little Lincoln prefers 75/25 the 25% argon runs hotter and cleaner (too hot for sheet metal). Thor brothers, great choice they make some awesome quality parts. The 4 link parts I bought from them their welds are freaking beautiful.

Are going to use a pan hard or watts linkage for tracking?
