(depending on electrode & settings) depending on variant and how aggressively you push it.
Electrode (rod) compatibility: supports welding electrodes around 1.6 mm up to ~4–5 mm diameter — that covers common MMA rods used for steel, mild steel, cast iron works.
Duty-cycle: about 60% at 40 °C (i.e. in ideal conditions, you can run roughly six minutes out of ten before the device requires cooling to avoid overheating).
