Once I have established the arc and begin moving forward, with or without a filler rod, the arc will suddenly flare-up very brightly for a second or two and then go back to the original arc shape. The flare-up is so bright that I have to stop and let my eyes adjust before I can continue. This happens intermittently every 5-10 seconds.
I never had this problem on the high-end Miller equipment I learned on at the local Tech College. I have welded with this machine with no issues in the past but this is my first attempt at welding 3/16 to 16gauge.
I am well aware most issues are "user error" but I can't figure out what is causing these flare-ups.
Any suggestions are greatly appreciated.
