Hi all. Hopefully someone can point me in the right direction. I'm familiar with TIG and have few problems welding mild steel etc so I thought I would have a go at some stainless today. I got hold of an old kettle which was being thrown out due to a leak between the spout and the body so thought this was as good a item to practice on as anything.
The kettle was expensive when It was new about years ago. It is made from 18/10 stainless according to adverts as the same model is still available new.
I turned my amps down very low and when striking up, there are either not enough amps or when turned up slightly, the metal immediately appears to just fizz and becomes very pitted and discoloured without actually forming a weld pool. The steel is very thin as you would expect for a kettle.
Now on the inside the kettle is thick with limescale. Could this have anything to do with it? The kettle itself is scrap anyway but it would be nice to know where I was going wrong.
