Yesterday i finally stopped by my local gas distributor and picked up a tank of C25. I have been using flux core wire since i picked up my welder (black Friday impulse buy ).
One thing is for sure I'm never going back to flux core unless i need to weld outside.
the following are my newbie (less than 6 hours of stick time) attempts at MIG welding.
My beads still aren't the most consistent.
A perpendicular cut through the bead to check penetration.
This butt joint was 1/8" bar no bevel or gap (my welder is only 110v), i still have an issue with little pin sized gaps.
Is there a simple formula to calculate bevel and gap, for a given ipm/amps?
