Quick welding question!
topless matt:
Gasless migs tend to leave slag in akward places uilike an arc.
Sometimes getting in the place you are trying to weld leaving a brittle weld that wont hold.
If you clean it up ok there shouldnt be any problems ;)

Nope, mig arc tig gas all fine on the chassis.
If anything gas, if the welder is inexperienced, which someone using a gasless mig is likely to be, is going to be the weakest weld due to cutting into the base metal before the filler rod in engaged.

So is gassed mig. The gas created an inert shrowd around the weld to stop oxydisation in the same way the coating on the stick or the wire roll does. If you involve lectriccery into the weld it's arc welding, the difference is how the oxydisation is stopped.
I aint going to comment on tig since I don't know owt about it, but for gas the idea is just to melt stuff till it's sticky, then introduce the filler rod, hence not needing to stop oxydisation, unless of course you up the temp, use a gas axe and then that's exactly what you want.

Beware gassless mig fumes as I am load to beleivethat the flux in them is carcenogenic and lots of places are now refusing to sell it! Thats what I was told by the cap at the BOC shop anyway.

You still get it at B&Q and Homebase?
I bought mine off ebay as it was dirt cheap for what i wanted!
