How to increase workpiece heat
and increase penetration:
(to weld THICKER workpieces properly)
How to reduce workpiece heat
and limit penetration:
(to weld THINNER workpieces properly)
a. Use MAX setting
b. Weld more slowly
c. Use faster wire feed
d. Use shorter stickout
a. Use MIN setting
b. Weld more quickly
