TECNA Hand-operated spot welding gun 7902P with pulse function - 2.5 kVA; complete with arms, electrodes + electrode grinder
- Versatile spot-welding gun for
body shops |
- Electronic synchronised timer with SCR 2 - 65
periods |
- Compensation circuit controls the timer only when current
current flow at the spot weld. Therefore excellent
results when welding on sheet metal with paint
oxidised parts or on galvanised sheet metal. |
| - Pressure setting with scale in daN |
- Additional lower arm connection to increase the arm
the arm distance. |
- Transformer of insulation class F, tested with 4000 V
alternating current |
| - Welding time with pulsation |
