MIG welding gas question.

[HarryMann]

I think it's a maladjustment of some kind, may too slow feed but just couldn't get on with the Argon mix to start with - the arc ball and melt area just seemed as if Oxygen were being fired into it, hard to explain, white, overheating? Went back to Co2, Ok again, but have since welded with Argon Ok, but on clean metal... thought Argon mix was supposed to be somewhat better when having to weld less than perfectly new metal

yo dudes,ive been using pub gas for the last 19 years with no real probs,i tend to get through two bottles of gas a year as i tend to be welding summit every other day...them farty little bottles are a waste of time and b****y expensive too!!!!,i run a 185 sealey on 0.8 wire,but tend to use it for gates railings industrial stuff etc,they dont really have enough settings for me personally to achieve a perfect weld on panels(great for chassis tho),for body repairs i use a clarke 100 with 0.6 wire,you can really turn these babies down for a finely tuned constant weld bead on the most "heath robinson"of panels....just my opinion of course,but works for me..........p.s..........good thread!!

pub gas is fine. gas welding outdoors is pointless on an average british windy day though, flux core is poo too.

yeap weazlechin,welding outside is a big steaming mound of poo...i tend to drape a thick sheet,or a leather apron around me if its windy/if your under the vehicle i tend to lean sheets of ply along to block the wind......now welding outside when its blowin a force 9 gail with tropical rain in a muddy field is an altogether different puppy(thank christ i sold me land rover!)....wuff wuff
