Ok, got myself a mig from ebay, its a portamig 211.tried it out, set it up as per this site.Have not got my argon bottle swapped over to argoshield or whatever energas equivalent is called yet.Anyway connected it up to pure argon bottle.
Weld looks neat enough but arc very unstable and sparks everywhere none of this bacon in a pan sound. The steel is not ground clean but is new offcuts of 2" angle, 3mm thick,
Are the sparks cos the metals not clean or cos i am using pure argon,was thinking of closing my account with energas and using pubgas, there is a local extnguisher filling place near me.What do you think.Like I say the finished welds look good tried on some 1 mm too, good penetration but spark eratic and like a firework display.Tried different wire speeds and tensions, feels best on 5-6 on the feed.Using .8 wire cos thats what was in it when i got it.Also i dont know what type of wire it is, just presumed mild steel, its not stainless.
Help!
