TECNA Pneumatic spot welding gun, water cooled 7915 - 6 kVA; without arms + electrode grinder, with pressure maintenance unit and manometer, as well as hoses for cooling water and compressed air
- For workshop work with fast spot weld
sequence. |
- Integrated electronic synchronous timer
with SCR 2 - 65 periods. |
- Compensation circuit controls the timer only in case of
current flow at the spot. Therefore excellent
results when welding on sheet metal with paint
oxidised parts or on galvanised sheet metal. |
- Control with welding current regulation of particularly
thin sheets, stainless steel sheets and wires. |
| - Base for mounting on work table. |
- A pressure switch in the clamp controls the timer,
as soon as the correct working pressure between the
between the electrodes. |
- Additional lower arm connection to increase the arm
of the arm distance. |
- Arms 7401/7402/7403/7404/7405/7406 and 7407
available separately. |
- Insulation class F transformer, tested with 4000 V
alternating current. |
| - Welding time with pulsation ( version P ) on request. |
