Thermal Overload Protection; Putting Into Operation - JESS Welding conMIG 300 Betriebsanleitung

conMIG 300
Welding voltage selection
12-step voltage selector switch
Control functions
Wire feeder and spot welding time can be adjusted
Cooling the power source with a quiet fan
The fan is activated by a thermostat and does not begin to operate until the power source has warmed up.
It 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 socket
The central connection socket 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. For the connection voltage and power consumption:
