weird welding?!?!

[Locky]

looks like a weld over paint or some sort of contamination, is the steel thinner in the joins ie. ground down?

Skov
welding gas was on for both pics no change made to regulator

yes the steel is thinner as it's ground at an angle

maybe I'll run a few more beads on a sample piece of steel and have a play with the wire feed settings

Didnt weld in a different part of your garage, where it is windier and its blowing away the gas?

[rapidtornado]

yes I did actually... I shifted location so that could have been the issue, didn't think of that

Definately looks like a loss of shielding gas to me.

Would have needed to be quite draughty to have a total loss of shielding gas, perhaps you need to up the gas flow rate a little

Definately make sure that you protect the welding area from draughts tho.

Can't tell by the picture but if that is 3mm material being welded, personaly I would up the welding current up a little ( assuming you are using a 150 amp mig )

found out the problem!!!! despite the fact that I had a brand new tank and only used it for 45mins just disconnected the tube to the welder and found the tank was empty!!!! absolutely crazy! I know they are disposable but 45min is a joke... best get onto the supplier me thinks!

Thanks for the help guys
