What am i doing wrong?

[trampintransit]

OK...Clarke MIG 160, 0.8 steel wire, argoshield universal. Trying to stick a length of square section to the floor of an old car. The car floor is buffed back and is surprisingly good clean metal. The square section is likewise clean. The earth is good. I'm welding 'uphill' pointing upwards. Doesn't matter what settings im using , the wire seems to be 'burning off' and balling. It's falling clear of the metal, clogging the coller and just not penetrating. This is kinda new. The arc also looks kinda green.????? As soon as i put the earth on a bit of the square section on the bench it welds just fine????

what settings do you have on the welder?

 

[gavuk]

Green arc?....zinc plated?

My thoughts too. Would explain the wire balling up as well.

any white powder left behind after the weld ?

I have the same welder, normally my wire speed is 5-6, power set at min.
Hope this helps.

Also set the power dial on 2 and your gas flow rate
to work at it's best should be set at 10 lpm.

is your lance getting a bit twisted? Could be the wire is being held back?

Blow the liner out with compressed air, make sure it's feeding the wire smoothly!
