Spot Welder 7900 2kVA c/w Timer 230V
• Lightweight professional spot gun for car body repair.
• 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.
• All transformer are coated with F class insulation material that does not dry out and become brittle.
• Tests are made using 4000V.
• Force adjustment with scale in daN.
• Additional arm couplings to provide larger opening between arms.
• Supplied complete with 125mm arms.
• Large choice of arms and electrodes.
