11. Brief description
The dual MIG 250E 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.
To optimize the workflow, two separate welding control units for two different types of welding have been
integrated.
Weld-grade adjustment (for each side)
dual MIG 250E:
12-grade switch
Control functions (for each side)
dual MIG 250E:
wire feet rate and spot welding time adjustable
Wire feed by 4-roller drive
Current-source cooling by low-noise fan
Thermic overload protection
In the event of extremely high load or ambient temperature followed by an inadmissible high Operating
temperature, a built-in Thermo switch 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
accordance with European Standard EN 60 974-1.
