  • 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 sheet and similar.
  • Cos Ø control.
  • Manual force adjustment with scale in daN.
  • Additional arm couplings to provide larger opening between arms.
  • All transformer are coated with F class insulation material. Test are made using 4000 volts.
  • Supplied complete with 125 mm arms.
  • Large choice of arms and electrodes.

Pulsation weld time control available (P version).
