Tecna 6kVA spot welding gun – 6kVA pneumatic, water cooled.  With a 2 + 2mm spot welding capacity this pneumatic spot gun is designed for repetitive use in professional bodyshop environments.  A 6kVA spot welding output at 50% duty cycle, with a 18kVA maximum output power.

 

Key Features:

  • Pneumatic air-powered arms.
  • Fully water cooled portable spot gun
  • For high operating rate works in car body repair and light production works in industry
  • Compensation circuit starts the timer only when there is a proper passage of current which enables performance on oxidised 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 diameter, on stainless sheet and similar
  • Balanced construction for easy operation
  • Thread base for fixing on a bench
  • A built in differential pressure switch operates the timer when the electrode force is correct
  • Additional arm couplings available to provide larger opening between arms
  • Includes either 250mm or 350mm arms and electrodes, or as bare unit.
  • Extensive range of optional arms and electrodes available to suit this model – 150mm, 250mm, 350mm or 500mm – enquire for details.
