And with a decent supply behind it, you will occasionaly blow fuses as the inrush will age them pretty fast.

Watching Master weld my Pre cats I noticed the width of the weld laid. Probably 7 or 8mm wide.

The weld in the pic, although neat enough, is probably only 3mm wide. 4 at the most. Does that also point to too thick a material for the machine?

[chrisgixer]

As a guide the holes are about 6mm dia.

Oh the metal thickness is way beyond the machines capability.

I was laying a fillet down so was slightly wider then I would normaly do on a butt joint.

[Shackeng]

I only ever used it on VW floorpan thickness panels, and it was fine for that, but really not much use (for anyone ) for anything much thicker.

In that case, clearly, I'm much better than I thought I was. 




If only I knew/understood what I'd done.

Your laying a bead down but as the machines power is to low for the metal thickness its not penetrating and hence the ridge.

Laying a bead is one thing, laying a well penetrated bead is another.

Do you not have anything thinner?

[chrisgixer]

Yes I have a tigra exhaust I can weld back together. It's actually in very good nic as the Lady has now retired and the car is always garaged. Even the clamps where rust free.
It failed through metal fatigue where the pipe enters the rear of the back box. The weld is attached to the pipe, but metal fatigue has torn the surrounding metal work. So access aside, I'll see if I could have re welded it with a best guess at the settings, rather than replacing with the Eternal one it has now.

Then generally cock about with it. That's the sort of practice I really do need.

[chrisgixer]

I should add, it's the original exhaust from a 98 car, so although visibly ok on the outside, it will be much thinner internally.

Only one way to find out.

Of you go then...

There is a fuel tank back there as well ,just saying

[05omegav6]

I hope think the exhaust has already been replaced and is off the car

Had to stop play, H says the lights in the house where flickering on and off.



Similar story, not enough penetration.

Back on topic, what is the problem with welding?
