Ozito 100A Gasless Inverter MIG Kit settings for common jobs
Quick answer
Starting points scale from the 100 A rating: dial in on scrap, not on the job. Voltage and wire speed (or amps for stick) move together — when one changes, re-check the other.
Starting points by job
| Job | Starting point | Note |
|---|---|---|
| Thin sheet / sheet metal | 30–40 A | Short, tack-then-stitch approach on thin material |
| General fabrication | 60–80 A | The everyday working range for this machine's class |
| Thick section / full output | 80–100 A | Watch the duty cycle at rated output — check the spec plate |
How to tune in 30 seconds
- Set the job on scrap of the same thickness and cleanliness
- Start low, strike, and listen — a steady crackle is right; popping means wire speed low or stick-out long
- Adjust one dial at a time in small steps and run a fresh bead each change
- Write down the final numbers — the settings sheet beats memory every time
