Spot and projection welders - Items 6121N-6129N - 90-200 kVA

Versatile welders designed as to perform both spot and projection welding.

The mechanical frame of these machines has been designed so to minimize the flexions. Also, this body, combined with the inverter technology, allows to obtain high quality welding.

The six working modes provided by the TE700 control unit allow to choose the most suitable welding mode for the material to be welded. It is also possible to implement a proportional valve in the pneumatic circuit thus ensuring a high work pressure precision and constancy. The proportional valve is programmable directly from the control unit and allows to match to each program its relevant pressure value.
