We recommend that you always fit a teflon wire liner.
Just make sure you use the right gas mixture wire and tweak the voltage little higher than you would normally use for regular steel. You may ve recently gotten some inert gas welders under 1000 bucks and you d be keen to know. Stainless steel is popular for welding since it s a highly resistant to corrosion. And they say you re going to need some solid stainless steel wire and shielding gas.
The answer to your first question is yes you can mig weld thin gauge stainless steel in a short circuit mode with compact type 120v or 230v input power mig welders see example in figure 1. Welding is a way to combine pieces of stainless steel together for repair work and even craft projects. If you already have some experience in the world of welding you should be completely capable of mig weld stainless steel even with a regular hobby welding machine. This will ensure good wire feed as well as preventing wire contamination.
To begin a weld set the steel in place over a welding table using clamps and jigs. Using steel for mig welding is a bit complex. The main reason being it contains higher percentages of chromium as compared to other metals. Firstly as with any welding process make sure your mig welding machine is set up correctly for welding stainless steel.

Stainless steel can also be welded with a lot of processes but a lot of operators still ask can you weld stainless steel with normal mig wire. You can mig weld 20 gauge stainless steel but you need self shielding flux cored wires which don t require external gases. However it will give quality cuts as compared to other metals that leave a slag. Also the welder should be able to use the wire and the torch has to be negative.
The diameter of the wire should be between 0 25 and 0 35. The machine would have the same amperage and resulting material thickness capability with stainless steel as it does with carbon steel.
