Hi,
I am looking at building an exhaust for my car myself, I have got all of the bits I need to do it and I think with a bit more practice I can get somewhere near good enough to knock something up, for my own use anyway.
The issue is I have a Clarke 151te and a bottle of 75/25 argon/Co2 I have got some stainless wire for the machine as well. I have been doing some digging online and initially I was under the impression I could grab a hobby bottle of pure argon to knock this out with but a bit more reading has led me to find this will lead to a poor pool and high welds?
I appreciate that if a job is worth doing it is worth doing right, that said its quite possible in the near future I will be upgrading a lot of the car, including my home made exhaust, its more of a practice project/bit of fun really. I am not going to be back purging it as I make it. My question is, how much is using the 25/75 going to damage the corrosion resistance of the weld? A lot of the info on the web reffered to food grade welding and helium mixtures being a nessecity I can appreciate any corrosion is going to be a big deal here, if it is only an exhaust the risk of some tiny spots off rust isn't likely to bother me!
Thanks a lot,
Tom
