Tecna rocker arm spot welders, foot and air operated 4640N..4649N, from 16kVA to 25kVA.
The arms are adjustable in length for greater flexibility at work.
Copper-chrome electrode holders suitable for heavy duty and long service life, designed for straight and inclined mounting; the travel of the welding electrodes is adjustable.
Welding transformer encapsulated in epoxy resin, water cooling of the transformer, arms and welding electrodes.
Microprocessor control unit TE101; the TE101 welding control measures the welding current and the current through set limits.
Resistance welders with pedal operation have adjustable electrode force; a microswitch commands the welding cycle when the set value is reached; the pedal is adjustable in length.
In resistance welders with pneumatic drive,the air operated lubrication free cylinder eliminates oil mist.
Electrode force adjustment with air filter reducer with gauge; semi-automatic drainage system.
Electrode speed control valves, shock absorber for cylinder's end of stroke and air discharge silencers.
Two-stage electric foot pedal, that besides its normal use in automatic and single spot mode, allows the operator to bring the pieces together and to weld them only when correctly positioned.
Pre-arrangement for the connection of a second electric two-stage foot pedal.
The addition of the second foot pedal allows to recall two different adjustments of time- current; this function is helpful when different kinds of welding are to be performed on the same piece.
