Hello, bought a mig welder couple years ago. Ive done a few projects in mild steel but wanted to try aluminium and stainless. Theres some good info on the main site but leaves a lot of questions
Alu wire I bought 0.8mm 5356
Stainless I bought 0.6mm 308L, both super6 brand which I also use for 0.8mm flux core.
Ill using a 110 litre disposable 100% argon before I decide to buy a 9L rent free.
Would like to know is there any way to identify grades of alu or stainless as I have plenty of scrap Id like to use.
Stainless - Id like to make a motobike exhaust header (cbr250rr). I read that stainless does not like working between 300-700 degrees C. Above 700 to use 308H (normal carbon filler?). Am I correct with 308L?
Would like some idea how thick I could weld in aluminuim. I have some 1/4" bar which would be ideal for some parts but I imagine thats asking a lot.
Does torch liner need to be changed for stainless or just aluminium? I assume my liner is a cheap nylon type. Im using a sealey 130A mightymig if anyone can recommend a liner. Is it posible to bodge a euro torch teflon liner to fit my torch?
This is one of my past projects

Small bike stand from 25mm 1.5mm box.
I will be making a more substantial stand from 42mm, 3mm wall round tube. Round is obviously stronger Im just wondering the easiest way to cut a round profile for joints. I can mount some tube with sandpaper in drill for final shape but I guess rough shape has to be drawn on and angle grind?
