Items 3416-3418
- Rocker arm pneumatic spot welders with TE90 control unit- 16-25 kVA
| ROCKER ARM PNEUMATIC SPOT WELDERS - ITEMS 3416-3418 - 16 TO 25 kVA AT 50% |
| MAIN WELDER FEATURES |
|
 |
- Adjustable arms up to 320 mm, enabling to adjust the welder according to the work exigencies.
- Chrome-copper electrode-holders for heavy duty and long life, designed for both straight and angled assembling.
- Adjustable electrodes stroke, enabling to reach the max. working rate.
- Water-cooled transformer, with epoxy resin coated windings.
- Water cooled arms, electrode-holders and electrodes.
- Synchronous SCR contactor insulated from cooling water circuit with protection thermostat.
- All models have been designed for both single and automatic cycle.
- Two stage electric foot control for clamping and welding pieces only if correctly positioned
- The welder has been designed for connecting a second two stage electric foot. This additional electric foot enables the recalling of the twin pre-setting for time and current, useful when it is necessary to carry out two different welds on the same piece.
- 24 Vcc 5 way solenoid valve.
- Double effect pneumatic cylinder, lubrication free against oil mist.
- Electrodes force adjustable by means of a protect built-in compressed air filter unit with gauge-pressure, with semi-automatic moisture discharging.
- Electrodes speed regulators (both opening and closing), cylinder end-stroke shock absorber, and silencers for compressed air discharge assuring the minimum noise.
