Quick welding question!
topless matt:
Well, he was talking some sense, some of the fumes released if enough volume can be harmful to health and some can lead to the catalysation of carsogenics.

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.

i know that any form of welding involving electrickery is "arc" welding but an MMA/arc/stick welder has a flux coated electrode like the gassless mig which is what i ment and i belive 90% of people reading knew what i ment. and the fumes given off of MMA/gassless mig IS a carsonagenic.

my bad then, I'd concider gas welding to be using oxy and accetlene (spelling?), and mig to come under the catagory of electric welding (since not actually using the gas to weld)
lee celtic:
The man fro BOC would say that ......he sells GAS. :lol: :lol: :lol:
The only problem I have with gassless is after 20 mins of welding I can't see through the mask because of the white powder on the lense :cool:
carbore:
He also sells (or sold) non gas welding kit.
And my google search showed a lot of stuff about the risks of welding.

Mind you if you dont do it day in day out the risks are likley to be small, but id be careful about that white powder on your helmet (no sniggering at the back)
