hi guys,

A close friend of mine has a gasless MIG welder. We've tried welding our own home made manifold sometime back for a suzuki jeep. I am now very tempted to save some cost and weld my own DP with the MIG welder. I need some advice on the difference between gas and gasless mig?

His mig is gasless but has a regulator that allows gas welding if needed. I'm sure gas welding is much better, but what are the benefits? What gas should we use, if commercially available for welding 304ss 16gauge pipes?

What feed is best for a turbo exhaust system? 304ss

What voltage should i crank it up to for 304ss 16gauge?

Finally, are there any exhaust plans for the CRX? I'm asking because an industrial fabrication company near my place can do a series of bends on their machine and the guys there are really cool, they need the "floorplan" of my exhaust system and they can plot the axis onto the computer and i'll get my mandrel bends in one piece. I'm thinking of a 4 axis bend, from after the DP straight down pass the gear linkage, two 90degree S bends followed by another 90degree bend upwards and another 90degree bend towards the back of the car.

Basically copying the original exhaust plan, but with 3" OD 304ss. I only plan to have 1 joint at the rear right suspension area.

They do not have a vehicle ramp, so the only way i can get them to do it is to get the plan. I will need a centerline Radius for the bends if possible.

Any suggestions will be really helpful!

I hope i've made myself easy to understand.

Thanks guys!

 

You won't need much power to weld 16 gauge steel. You will need to adjust the wire feed and voltage to get the desired welds- there are no "settings" and it is machine dependent.

A local welding store will hook you up with the right gas and wire for stainless welding.

For the "floorplan"- just get PVC 3" pipe and make a mock up.
