20. Brief description
The inoMIG 350 / 400 welding units are suited for welding thin sheet (motorcar parts) as well as extremely thick
materials (industrial use). Very good results are achieved also in welding stainless steel and aluminium.
Control functions
See control box MC.
Wire feed by four-roller drive
Current-source cooling by low-noise fan
The fan is switched on by thermostat control and runs only when the current source gets hot. During weld off
periods, the fan switches off as soon as the current source has cooled down again.
Thermic overload protection
In the event of extremely high load or ambient temperature followed by an inadmissibly 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.
