whiskers and suckback
Practicing 4g open mig root & flux core fill and cap.
machine set @ 17.0V with 186amp, with 1/16 landing and 1/8 gap. I feel confident in positioning and what I can see, but I do get whiskers if I try to advance the puddle, but I’m scared that staying in the puddle and going further up on the walls will risk penetration.
I also noticed these plates wasn’t cut the best so it’s possible the gap might have went to a 5 32nd in the middle and shrinked back down to an 1/8th towards the end of the plates.
Any tricks you guys have for run ins like this on a test?
