Current limit exceeded!

Current Limit Exceeded

Fronius · TPS i Welding Machine

What does Current limit exceeded! mean?

This safety function activates during MIG/MAG welding when the characteristic-dependent current limit is reached. If the welding power is too high, the arc may become smaller and extinguish. The welding machine automatically reduces wire speed and welding power to prevent arc extinguishment, and a corresponding message appears in the status bar.

Common Causes

  • Welding power is too high for the selected characteristic.
  • Characteristic-dependent current limit has been reached.
