Tig or mig ?

[Mathius]

I will modifying the fuel tank for EFI. Is it best to use TIG or MIG? Last time i did it i had trouble with leakings. And had to grind and weld again so it warped. I used mig. Now I have bought me ESAB 250 amp Twintig TIG and have my old 140 Amp Kemmpi MIG. What to use. Thanks for any input...

It doesn't matter if you are using the correct alloys and you are skilled with either machine.



There is nothing magical about a TIG welder, it just gives you more control because YOU decide how much filler to add, and YOU decide on the fly, how much heat.

You can get the same results with a MIG welder, if you know what you're doing.

So do whatever you feel the most comfortable with.

Oh, and peep in on this thread: https://www.pro-touring.com/forum/sh...hlight=Mathius

We fought out the whole TIG vs. MIG thing a long time ago.
