need some welding help/advise Options

[Jeroen]

ok... having some trouble making nice welds
well, partially

below is a pic of a recent weld
usually, I can get a nice weld going. good penetration etc.
and then out of the blue, it'll start sputtering and globs of weld start to stack making thick ugly welds

what's my problem?
- hand/eye coordination
- wire speed
- amp setting

any tips/pointers?
please help me out... I hate the look of ugly welds and it's a huge PITA to grind 'm out and start over

Liner runs through the sleeve, and the wire runs throught the liner. Liners must be appropriate size for the chosen wire, or the wire can get kinked inside the liner. Liners can also get a kink in them if they are ever crushed or folded too tightly. Also check the tension on your drive rollers inside the machine. Prolly not the problem but check it anyway. Best way to check is to run your wire into a piece of wood, the roller should be tight enough to feed the wire but loose enough to free spool when the wire hits the board, this is to prevent the wire from "birdnesting' should you ever lose your arc. Yes it happens!
