40kVA MF Inverter Pneumatic Column Spot Welder

The frame of this line of machines has been designed by TECNA so to facilitate the operator’s work.
The control unit, the pneumatic commands and the pressure gauge have been placed at the top so to enable the operator to use them smoothly.
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.

40kVA MF Inverter Pneumatic Column Spot Welder

Medium frequency welder, designed to obtain high quality welding.
Chrome-copper electrode-holders for heavy duty and long life, designed for both straight and angled fitting on the arm.
Water-cooled transformer, electrode-holders and electrodes; transformer windings coated in epoxy resin.
Microprocessor control unit TE751 provided with wide screen.
(optional) USB port for data storage.
Lubrication free cylinder and pneumatic components which eliminate oil mist.
Two-stage electric foot-pedal for clamping and welding pieces only if correctly positioned. Pre-connection for an additional electric foot-pedal for the direct recalling of welding program No. 2.

This function is helpful when different kinds of welding are to be performed on the same piece.

TECNA TE751 is a middle frequency welding controller, it may work with constant current and fix.It is possible to store up to 150 different welding programs. Each program comprises several programmable parameters that describe the work cycle. In addition to the plain 4-stage welding cycle, the control unit allows the running of welding processes with pre-welding current, post-welding current, slope and pulses.

TECNA TE751 FEATURES

Simplified programming via 9 keys and a backlit graphic LCD display.
Inverter command with IGBT at medium, allowing choosing the inverter working frequency between 1000 Hz and 4000 Hz.
