Setup Tips
Always use clean and dry wire or rods
Use proper drive rollers for MIG
Clamp on bare, clean metal for MMA
Shield from wind when using gas
Avoid exceeding 5–6 minutes continuous weld at high amps
Troubleshooting FAQ
IssueLikely CauseRecommended FixPro Tip
No arc: Loose clamp, low amps: Clamp to clean metal, increase amps: Always ground to bare, unpainted metal
Electrode sticks: Low amps, dirty metal: Use 90–100A, clean surface: Use E6013 for easy restarts
Arc pops or cuts out: Loose terminal, poor rod angle: Tighten cables, use correct angle: Store rods in sealed container
Breaker trips: Overload or poor socket: Use 20A+ socket, rest machine: Never use long extensions
Turns on but no weld: Blown fuse or PCB fault: Check lights, get technician check: Use surge protector
Weak weld: Low amps, wrong polarity: Use 90–125A, correct polarity: Keep consistent bead speed
Excessive spatter: Long arc, dirty base: Shorten arc, clean metal: 15° rod angle helps
Overheat light: Overuse beyond duty cycle: Rest 10–15 min, lower output: Use in shaded, ventilated area
