OK, I see that stainless steel oxidation looks horrible. I also see that the surface is not smooth. I also assume that a tiny part of the weld will be weak because it has become oxidized. For food applications, I guess that a porous surface could lead to buildup of different substances or bacteria. ...

I am also worried about the color of the welds. No matter what I use, the welds are grey. Once brushed, they just look like the surrounding metal, but I understand that what we want is a straw or rainbow color right after welding. I just can't achieve it. The tubing is only 1.5mm thick (a bit less t...

I couldn't wait and just re-fabbed my own TIG torch. I just disassembled the one I had and got rid of the big handle. I connected a flexible rubber hose and cut a piece of stick welding cable which came together with my TIG machine (I don't do stick welding). As a result my torch is small, light and...

Thanks. I also have a question about the TIG handle. Can you recommend a handle that's got a flexible cable and doesn't necessarily cost a lot. The one that came with my Chinese TIG is just awful. The total weight of the cable is almost as much as the weight of the machine and the cable is stiff lik...

Thanks for the replies. I will buy a dual tube flowmeter. One tube will be for the TIG and the other one for back-purging stainless.

Maybe just put it in boiling water for a few minutes. Maybe this temperature will be enough to make the piece 'workable'.

Hello everyone I have just bought my first TIG welder and I am completing my accessories. I hope to enjoy TIGging as much as I like working with my MIG machine. Some questions: 1. There are two types of flow meters. One with two gauges and one with a gauge and a glass tube. Which one is a better, mo...
