Cooling the power source with a low-noise ventilator
The ventilator is activated by a thermostat and does not begin to operate until the power source has warmed
up. The ventilator switches off during pauses in welding as soon as the power source has cooled down again.

Thermal overload protection

If the permitted operating temperature is exceeded due to an extremely high load or ambient temperature,
an integrated thermal switch disconnects the welding current.
Central connection
The central connection allows the welding torch to be connected and disconnected quickly. All electronic
components are installed in the metal housing. The power supply is provided via a separate connecting
cable.
