Is Cusi3 suitable for replacing the bottom of a tractor diesel tank? I havent welded with it before so this is a learning curve, also I'll be using my new Kemppi Minarcmig 200
thanks
thanks
Don’t you own one of these yourself?It's brazing wire. Does the minarcmig 200 have a built in program for it ?

Ah yes I know the one.Mine's an older 180, not as sophisticated as the 200evo but it does most jobs nicely, stainless etc.
With a mig braze it’s done in dip transfer only. It doesn’t wet as well as a weld. Where it comes into it’s own is reduced heat input, reduced distortion, dissimilar material joints, galv joints with reduced fume, very thin metals long runs with reduced risk of burn through. All this is possible because your producing a brazed joint so your not diluting the parent material. It will provide a sealed joint but due to the colder transfer used it doesn’t blend smoothly on the toes like a weld so a little skill technique requiredThe tank's already been cleaned plus I'll probably be replacing the entire bottom with fresh steel. I was thinking the braze would flow and seal better with less chance of leaks than MMA?

Wire is expensive, pure argon too
It’s got lots of benefits. It’s great for automotive repairs and panels. How thick is the material you wish to join.so there are more benefits to using it in this instance than I first thought, thanks for the info
I've got a cylinder of Argon, hadn't realised how expensive the wire was though!
It’s right at home on those thicknesses. If you can afford a spool there is no reason why not to have a go. If not just do it with normal Mig wire.It'll either be 1 or 1.2 mm mild steel. Haven't checked yet, but I want to experiment with the technique as I can see it being usefull for letting in non structural panels on the classic cars I normaly work on.
Careful. If it’s not a known brand it could be full of all sorts of junk. £27 seems awfully cheap to me.found a roll on ebay for £27 which is the cheapest I could find. I'll give it a go and report back.
