No time like the present. I am self taught. I had experience in gas, stick, and mainly MIG. There are many folk who can help, on here esp, and for the visual, try youtube.

Thanks Hotrodder, just found out I cannot get 303 in flat at all, so I ordered 304 in 10mm flat, plenty of coolant and patience on the milling machine. I will be using 316L in sch 10, no place really for a good support on a 5 cyl Fiat Coupe.

I plan to fab an exhaust manifold for a turbocharged car. I was looking to use 303 SS, but I see from a suppliers website that free machining grades are not usually recommended for welding. What do you guys recommend

Do you not need a pulse type MIG. I TIG mine, but I have seen a MIG welded T45 cage, and the penatration looked terrible. The weld seemed to be sitting on top of the joint.

I am thinking of reduceing my rental payments on 2 cylinders. I currently use argon shield for the MIG, and pure argon on the TIG. What is the problems with using pure argon for both.
John
should have thought of that. I tried it this morning, and the weld is so much better. Having difficulty concentrating keeping the rod cover with gas, but practice will cure that. There is no yellow/green dust, but the weld is not 100% pretty, but I'm putting that down to the Ti not being...
I done what you said Hotrodder, I got a gas lens, and made sure the rod was covered, about 10 seconds of pre and post on the gas. I done some more welding, and it's the same. I am pretty sure it must be the filler rod. how do I know what Ti alloy I'm welding when I bought the exhaust systems...
I am currently making up a Ti exhaust for one of our racecars, from 2 system's. I have got some rods from a mate, but when I look at the weld, there is a yellow dust, and if cleaned off, the weld looks dull. If I weld without the filler rod, the wels looks lovely, and no yellow dust. Any idea's...
What about using T45 and an A31 filler rod. Elmdon or Proformance can supply, and A31 rods are easy to find, and very tough, esp if your looking at a mountain bike

Aluminium is always used by us. It's lighter, easier to port. Stainless steel will cause condensation, water droplets in the inlet, and icing problems on the inlet tract, it can also be difficult to start in cold weather, as the fuel can fall out of suspension in the airstream.

I have aquired an Arcos Lincoln Mini Mig, 200 Amp. When I switched it on, all seemed ok, except the power switch seemed very stiff, compared to my Cebora. It welded fine, but start smoking from the unit. I removed the side cover, and the middle coil of the 3 was very hot, and black. I googled...
