AIR OPERATED PORTABLE SPOT GUN 7911 - 7913 - 7915

Tecna Air operated portable spot gun 7911 - 2,5 kVA
For car body repair.
For maintenance and preassembly works in industry.
Complete with synchronous electronic built-in timer 2 to 65 cycles and SCR contactor.
Compensation circuit starts the timer only when there is a proper passage of current, which enables to perform on oxidized sheets, on surfaces with paint residues or on black sheets.
Current control with phase adjustment to carry out difficult welds, on very thin thickness, on rods with reduced Ø, on stainless steel sheet and similar.
Additional arm coupling to provide larger gap between arms.
A built-in differential pressure switch operates the timer when the electrode force is correct.
All transformers are coated with F class insulation material.
Test are made using 4000 volts.
To be used with arms item 7401/7402/7403/7404/7405/7406/7407.
Pulsation weld time control available (P version).
