• Fully water-cooled portable spot gun
• For high operating rate works in car body repair and light production works.

• The compensation circuit starts the timer only when there is a proper passage of current, which enables it to perform on oxidized sheets, surfaces with paint residues, or 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 sheets, 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 to provide a larger opening between arms.
• All transformers are coated with F-class insulation material. Insulation test performed at 4000 V.
• To be used with arms item 7512 – 7513 – 7514 – 7515 (on request).
