TECNA 3655 CF20 Direct current welder station
with inverter tecnology M.F. 25 kVA (1000 Hz)

Water-cooled pneumatic double program. Simultaneous connection of two tools, with automatic recall of the relevant memorized welding program, enabling to save time, avoid errors so to have a simple and safe working process. Fast Gun, patented pneumatic gun with adjustable stroke.

Car body shops repair works: spot welding with "C" gun, even for high strength steels both single-sided and twin spots, welding of nails and washers for sheet straightening (spotter function): localised heating with carbon electrode, sheet-metal spotting. By means of the inverter technology that allows a constant and high welding current, not influenced by the varations of the supply voltages and by the secondary circuit conditions, the quality of the spot is improved also on galvanized sheets, The high current value allows to save time resulting in a longer electrodes life. The reduced absorption balanced on the three phases reduces the connection costs.

The epoxy-coated welding transformer is water-cooled. Analog welding control unit and potentiometer, with two indpendent programs, time adjustment in cycles, pulses, elding current and compensation.
