Anyone here mig with stainless.

I just bought the Lincoln 175HD and with the help of tony1 I bought some sch40 SS pipe(kidding I bought 16ga) for my 3 inch turbo back exhast for my s2000. Id like to piece together and weld it myself with the welder I just bought. Or should I just tack it and then take it somewhere to get tigged?, its going to be 3 pieces with two V bands.

 

you can use 308L wire.

im pretty sure my weld pak 175 is basically the same thing as your 175HD

 

did you get it at home depot?
if so then yes it is just repackaged

 

what size wire?

yea its from HD. .025 wire works fine.

Its pretty straightforward. Shield with argon and practice a bit to get the settings right. On thinner stuff, its easy to blow it out if you are not careful, but once you get it down, its cake. I have seen several threads on it before, so a search might get you some more specific info.

Best of luck with your project.

 

I use a helium mix for stainless. Its really not that much harder than mild steel.

 

Tony, (wisconsin tony not tony1) there is a really nice welding place in tosa, and another one on hampton out in butler I believe, they are super helpful and will carry alot higher quality stuff than what home depot has to offer.

 

Short circuit on stainless is going to be a spatter machine.

Pulsed or Pulsed Spray is the only way to GMAW stainless

If you want any quaility than you really should get a hold of a GTAW welder.

TIG is def the way to go. I only use my MIG for mild steel

 

If you want to use wire for stainless, I personally use a high end material called Addifix 942. You can get it in .035 that has a flux core. No, this is not the typical flux core that people assume is gasless. It is a dual-shield type. Meaning you need at least 75/25 or straight 100 argon plus you have the inner core flux. When set correctly, you will have absolutely no spatter. It is a bit pricy though. About $40 per lb.

What kind of range does this have? I guess I should say how thin of material can it be used on?

 

I've migged up 304ss while "playing" around in welding class.

We were using 100% argon, and whatever wire they run as default in the welding class machines (usually welding 1/4" mild steel plate). It was either .030 or .035 wire.

You definately have to play around with the machine a bit initially, it's really easy to get burn through and a lot of penetration.

Attached is a pic, that shows the penetration. This is way too much, but it's about the best I could do. This was with the torch about 1" off the surface which is as high as I could go without losing the shield.

Note: I only did this to see what migging up tubing was like, I quickly moved onto TIG and never looked back.
