18. Brief description
The
conMIG 300
welding unit is suited for welding thin sheet (motorcar parts) as well as extremely thick
materials. Very good results are achieved also in welding stainless steel and aluminium.
Weld-grade adjustment
conMIG 300:
12-grade switch
Control functions
See control box MC.
Wire feed by four-roller drive
Machine cooling by low-noise fan
Thermic overload protection
In the event of extremely high load or ambiant temperature followed by an inadmissibly high opeating
temperature, a built-in thermoswitch cuts off the welding current.
Central connecting socket
The central connecting socket permits quick coupling/decoupling of the torch.
Sign S
designates that this unit is admitted for welding under increased electrical hazard in
accorddance with European Standard EN 60 974-1.
