Exhaust questions/tools...
I am looking at doing a BTM soon. I also have another need to either hire a welder, or buy a small unit. The one person I talked to so far about coming out to do 30 secs of welding or less wants to charge me more than I can get a small unit for.
Harbor Freight has one that is 90 amp, for about 110 bucks. My question is would that be larger enough for welding up exhaust pipe? Also my repair is welding a 1/2 inch bolt together. It is just a iron fence hanger, I think they are called J bolts... Anyway, it will have a little tension on it and be holding up the fence. So I figure I don't need full penetration. But would be able to come close since I would go all 360 degrees around the bolt.
Thoughts on this unit for exhaust pipe welding and my bolt issue are much appreciated.
