INVERTER SPOT AND PROJECTION WELDERS 6121N..6129N

LINEAR ACTION WELDING MACHINES

MEDIUM FREQUENCY, SPOT AND PROJECTION LINEAR ACTION WELDING MACHINES 90kVA..200kVA

Tecna medium frequency, spot and projection, linear action welding machines 6121N..6129N, nominal power at 50% d.c. from 90kVA to 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.

The inverter technology, which these machines are provided with, allows a higher welding quality, an extreme precision in time and current and a reduction in costs, installation ones included.

The welding time is adjusted in milliseconds thus allowing the best set-up.

The welding current is supplied continuously and constantly and is not affected by the dimensions of the welding circuit.

Ordinary welders use a single-phase welding transformer that supplies alternate welding current; the welding current is adjusted by the thyristors by means of the phase-shift technique.

This new technology employs an inverter supplied by the three-phase mains.

Inside the inverter the current is rectified, filtered by the capacitors and transformed by a IGBT bridge into alternate current at medium frequency (1000Hz).

It is used a specific welding transformer equipped with a rectifier that supplies direct welding current.
