TECNA 7913 Portable Spot Weld Gun – Pneumatic, Gyroscopic, 6 kVA Water-Cooled
WSI-SELECT – In-Stock and For Sale at Weld Systems Integrators
NEW TECNA 7913 Weld Gun – WSI Serial #: 08931
NEW TECNA TECNA 7913 pneumatic, gyroscopic, 6 kVA water-cooled portable spot weld gun [ WSI stock / serial #: 08931 ] IN-STOCK and FOR SALE at Weld Systems Integrators.
The TECNA WTG-7913 is ideal for body repair, light sheet metal fabrication, and other maintenance applications.
There are a variety of arms available for this unit, further enabling a wide range of applications. In addition, the TECNA 7913 comes standard with an electronic timer that operates the differential pressure switch when the electrode force is correct. A compensation circuit starts the timer only when there is a proper range of current which allows welding on oxidized sheets or materials with a painted surface.
WSI maintains an IN-STOCK inventory of new and used resistance welding equipment at our Warrensville Heights, Ohio location for quick shipment and delivery. Contact our knowledgeable sales team at 844-WSI-WELD or +1-216-475-5629 for immediate assistance.

- Fully water-cooled portable spot gun
- For high operating rate works in car body repair and light production works.
- Synchronous built-in electronic timer with SCR from 2 to 65 cycles.
- 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).
