PNEUMATIC SPOT GUN ITEM 7911 – 2.5 kVA

• Light and proved spot gun for car body repair and maintainance/preassembly works in industry.
• Synchronous built-in electronic timer with SCR from 2 to 65 cycles.
• Compensation circuit starts the timer only when there is a proper passage of current, which enables to perform on oxidised sheets, on surfaces with paint residues or on black sheets.
• Current control with phase-shift adjustment to carry out difficult welds, on very thin thickness, on rods with reduced diameter, on stainless steel sheets and similar.
• Additional arm couplings to provide larger opening between arms.
• A built-in differential pressure switch operates the timer when the electrode force is correct.
• All transformer are coated with F class insulation material that does not dry out and become brittle. Insulation test performed at 4000 V.
• To be used with arms item 7401 / 7402 / 7403 / 7404 / 7405 / 7406 / 7407 (on request).

Pulsation weld time control available (version P).
