5.2

Overheating protection

A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.

5.3

Inductance connection

Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.
