if you have a wire feeder arc welder, a mig conversion kit from lincoln electric is just under $100.. if you have a stick arc welder you have to buy a spool feed, and a gun and a gas kit.. not worth it, it will cost more than buying a mig and you can prolly pawn your stick welder for cash..

keep in mind you also have tio buy a cylinder for the gas.. I got a big 80ft^3 filled for $130 and it is $24 to refill

 

wow that is really ghetto, i guess ill get a mig instead of a wirefeed, it would be hard to sell anything with those kind of welds.

 

so, welds are good for hold pressure?(boost)

 

Well yes? why wouldnt they? welds are incredibly strong

 

ewwww heh, those stick welds look a lil but if they work its all good, ive been messin around with this cheap 70amp wire feed and it welds alot better than i expected..

 

well guys i suprised the hell outta myself today. had some old ss 2.5 exhaust pipe so i decided to give my dam eletric another go.

i found the best way to do it. is to lay a spot weld then another. u hold it on to long and bang u got a hole.

it looks pretty good.

 

so the cheap $170 welding machine is a way to go for some ghetto homemade manifolds

Jeff-

 

I made my manifold with flux core wire from my cheap *** lincoln welder, and it works, but could look way better and not leak so much. I think mig with gas is the way to go. How much are you guys paying for renting cylinders/buying gas?

Is it OK to just use CO2? I read somewhere that it is.

 

I bought my tank for $130 filled, it is an 80 ft^3 which is pretty big.. it stands waist high... it costs $24 to refill it with co2/argon mix
