| Items 4602N-4606N
- Rocker arm, foot operated, spot welders - 16-25 kVA
| ROCKER ARM, FOOT OPERATED, SPOT WELDERS - ITEMS 4602N-4606N - 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.
- Adjustable electrodes force, a microswitch starts the welding cycle when the desired pre-set value is reached by operating the foot control.
- Foot control adjustable in length.
