Using electric welder for the downpipe?
I am planning on using the electric welder that i got from Home Depot to weld the downpipe onto the exhaust side of the turbo. Will it hold against the heat? And does it do a good job like a Tig/Mig welder?

Is it a 120 welder? Those are known for there butt cold welds that tend to break before the metal.

Re:Using electric welder for the downpipe?
That was the extent of my knowledge as far as welding goes. I just know about those 120 welders being crap. My uncle used one to build a sand rail and it is constantly breaking at the welds. The welds should never break before the metal unless the weld was too cold. It will work, but I wouldn't use it for anything important. It would be ok to use for exhaust work and simple jobs like that.

ive rented it once and i think its a lincoln weldpak 100. many people have had success doing downpipes. just practice on a few pieces so you get a feel for the voltage and speed you need. remember, even tho it fills up on top it may not actually be welded on the bottom. try hammering your work and see if it chips off. i would even grind it down to see if it made a good seam and keep doing a few more passes. youll get the hang of it.

Re:Using electric welder for the downpipe?
o.k. here's my 2 cents. when doing my custom downpipe, i bought the cheapest 110 volt to 100 amp arc welder i could get. it was a huge p.i.t.a. to use, and i don't recommend them, but my down pipe has held for a few weeks now (even on some hard, hot dyno runs!). i only plan on this d.p. to be temporary. also, from what i know (not much 
) i would recommend a mig.

Re:Using electric welder for the downpipe?
dont listen to the people that say 110 volt welders dont work...i personally have a lincoln wire feed welder without gas, and have used it to weld in frame notches on a truck, airbag supension mounts, modify control arms, make two manifolds (welding cast to steel mind you) and make charge piping for two cars, as well as numerous exhausts...it just takes practice i guess...never had a weld crack on any of the above, except one exhaust hanger that came off when the pipe hit the ground on a bump

I'm not sure what exactly a 120 welder is. But it is similar to the one that can be found at Walmart. It is those CampBell Hausfeld kind of welder. Not sure what kind it is. And it use these rods to weld things.

Re:Using electric welder for the downpipe?
he's referring to the type of voltage, the type of plug the welder uses. 120 can be plugged into the wall but the bigger ones require clothes dryer type plugs. I have a 120 also, haven't really used it yet though. If it uses rods to weld, it's probably an arc. Most people here are talking about MIG, which is a welder that's wire fed.
