MMA Stick welding problems
•
Stick electrode ‘blasts off’ when arc is struck
Welding current set to high, reduce amperage or use thicker electrode
Contaminated electrodes or material
•
Electrode sticks in weld puddle
Welding current is set too low
Arc is too short, keep electrode further away from work
•
Excessive splatter
Too long an arc, keep electrode closer to work
•
Poor penetration
Travel speed too fast
Too much welding current, reduce welding amperage
•
Porosity in weld
Electrodes are damp
Arc too long, get electrode closer to work
