MAIN WELDER FEATURES
Car body shop repairing works: resistance spot welding of sheets, sheet straightening with spotter (nails or washers), localised sheets heating (carbon electrode), screws and rivets welding, inox sheet-metals spotting.
Synchronous SCR welding control unit, welding time adjustment in cycles and pulses, welding current adjustment and compensation function.
Items 3484 and 3487 allow simultaneous connection of two tools with automatic recall of the relevant welding program, enabling to save time, avoid errors so to have a simple and safe working process.
The welding stations with epoxy-coated transformers, are supplied equipped with:
- extra-flexible cables L= 1800 mm, 150 mm.
- standard trolley.
- pair of standard arms, L=107 mm.
Available versions:
Item 3481 - Hand operated gun, single program
Item 3484 - Hand operated gun, double program
Item 3487 - Pneumatic gun, double program
Item 3487/W - Pneumatic gun, double program, with support for optional water cooling arms and cables
