Welding thin metal with Murex 235

[stichill99]

Hello All
I have a Murex 235 which I have done a lot of fabrication with box section etc and got on well with welder. I have bought a resto project mk1 golf and it needs a few areas welded. I thought I would practice on some thin metal about 1.00 mm and with welder on lowest setting it just blew straight through using 1.00mm wire. I looked at manual for machine and it said it ranges between 20 to 30 volts and the bottom amp setting is 40 amps. On the thin welding guide on here it says you need to use 25 amps so what I would like to know is my welder just no good for welding thin sheet? Would it make much difference using 0.8mm wire?

Has it got a wire feed pulse feature on it? If not it should work ok with .8mm wire, triggering the torch on really thin material.

Can it use 0.6 wire? thinner the better. 40amp is not great for learning but possible. Ive welded thin body work with 40amps on 0.8 wire before successfully but you have a lot less margin for error.

25amps is ideal, 30amps is good, 40amps is at the top end especially using 0.8wire.

Thanks for the reply's . I think I will give it a go with 0.6mm wire and see how I get on!

you might have trouble running .6 if you have a long torch think i read that somewhere may someone can say for sure
