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
| Issue | Likely Cause | Recommended Fix | Pro 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 |
