Novice MIG Thin Metal Advice

[Dominiks]

Hello All,

I am starting a project where I need to weld thin mild steel 0.6mm ideally.

I have seen some MIG welders that state they can weld this thin but the amp output of different models varies wildly.

So can someone help me, is the general rule of thumb, the lower the lowest amp setting the thinner the metal can be welded? I will not really need to weld anything over 1-2mm so max power output is not an issue.

I am not sure TIG welding will be the best thing for a novice but I know that would be the best system and I don't want to waste money buying a welder that's just going to blow holes in everything I use it on. Budget up to £500.


Any advice would be greatly appreciated.

Many Thanks

Dominik

In my opinion welding thin steel with MIG or TIG isn't that difficult really but you do need to practice, practice and then practise some more. MIG is probably the easiest for a novice though.
Have you looked at the thin metal technique ???

Yes, that is correct. As Langy says, have a look at the tutorial for thin metal here.

It will help if you are able to put some copper or similar as a heatsink at the back of the joint.
