, 09:24 PM at work i want to ball the end of my green pure tungsten electrode for aluminum welding. i put it to DCEP, hit the pedal, and nothing happens. put it on DCEN and hit the pedal, and it will arc, but i dont get the nice balling effect. why wont it strike an arc on DCEP ? its a miller syncrowave 250 water cooled unit.

Rule #5: You DO NOT need copper or any other specialty metal to ball your tungsten. Rule #6: If you can afford both red and green tip electrodes, ONLY BALL GREEN for aluminum. Keep RED pointed for steel. Rule #7: File along the axis of the electrode, not around the circumference. Rule #8: DCEP for balling.

Tungsten can be cut with an abrasive cutoff wheel or ground through with the corner of a grinding wheel. Do not cut the electrodes with a wire cutter or break them by bending. This may result in unseen fractures at the cut ends, which can cause an erratic arc. Tungsten electrodes usually come with blunt ends that need to be sharpened before use.
