MIG WELDING

[Guy]

as the entire area is to be rapainted .. splatter is not an issue (the whole roof needs to be sanded back anyways)

So I should be able to weld sucessfully on bodywork woth flux core
yay or nay ?

[N*A*M]

for sure if your technique is up for it

Gasless wire not only splatters heaps more than solid wire and arc electrodes, it is a lot weaker weld as well, thats why I dont use it on anything thats going to be subject to a substantial bit of strain.
You'll always get much more rutile strength from solid gas wire or stick welding than that gasless poo!
I thinks it's ok for thin sheetmetal though if your prepared to clean up the mess after.

hired a big tank from BOC and just welded up some bit and pieces and its great. sepnt about an hour tackn bits togther using differnt settings etc.
it was just a matter of playing around with

Hired a big tank?

Yeah i'd go a stick welder over a gassless mig anyday.

Maybe he got a big "bottle" instead

well I am off to borrow the gasless, Will let you know how it all goes ...

I went through all the arguments for buying MIG was told that welding in all it's forms still comes down to one thing, temperature control.

So I got an OXY set, figured that if I could master temp control with an OXY then I would have sufficient grounding to move onto others.

Additional benefits it cuts and is a hell of lot safer than a nine inch grinder.

my 2 bits worth

Flux core mig wire was designed to be used on job sites and out in the wind,were your gas is normally blown away leaving you with tiny little bubbles called porosity.The only reason they made flux core was because the mig is so much faster than the arc welder,but couldnt easily been used in wind without wind breaks and stuff,so the best thing for you to do would be to throw that wire in the bin.Have a nice day i have cleen panties on.

your on the money Bundy_harry... oxy is the shit! but a different can o worms to mig/stick in terms of control, I can oxy fairly good plate or pipe but its killing me trying to learn to arc smaller stuff
