Car body repair spot welders

Direct current welding station with inverter technology - Items 3650-3655

  • Print

Car body shop repairing works: spot welding with "L" and "C" gun; single sided and twin spot welding; welding of nails and washers for sheet straightening (spotter function); localised heating with carbon electrode; screws and rivets welding, sheet-metals spotting.

By means of the inverter technology that allows a constant and high welding current, not influenced by the variation of the supply voltages and by the secondary circuit conditions, the quality of the spot is improved also on galvanized sheets. The high current value allows to reduce welding time resulting in a longer electrodes life. The reduced absorption balanced on the three phases reduces the connecting and consumption costs.

 

Analog welding control unit with potentiometer, with two independent programs, welding time adjustment in cycles, pulses, welding current adjustment and compensation function.
Allow simultaneous connection of two tools with automatic recall of the relevant memorized welding program, enabling to save time, avoid errors so to have a simple and safe working process.

The welding station is supplied equipped with:

  • Item 3489 - Adjustable height trolley with tray and arms holder
  • Item 5127 - Pair of water-cooled arms diameter 22 mm, L=152 mm
