TECNA HAND OPERATED PORTABLE SPOT GUNS (7900-7902-7903)

Hand Operated Portable Spot Welder item 7900 - 2 kVA

The TECNA 7900 manual portable spot welder is a lightweight and optimized solution for welding operations in the automotive repair industry. Equipped with an internal electronic timer synchronized with SCR, it allows precise adjustments from 2 to 65 cycles. The compensation circuit activates the timer only when current flows through the welding point, ensuring optimal results even on painted, oxidized, or black sheet metal.

The welding force is adjustable on a daN scale, while the additional lower arm fitting allows a wide opening between the arms, improving accessibility. The transformer, insulated in Class F and tested at 4000V AC, guarantees high operational reliability.

Hand Operated Portable Spot Welder item 7902 - 2.5 kVA

Designed for versatile use, the TECNA 7902 manual portable spot welder is ideal for applications ranging from automotive repair to general maintenance. Like the 7900 model, it features an internal electronic timer synchronized with SCR, adjustable from 2 to 65 cycles, and a compensation circuit that optimizes welding quality on painted, oxidized, or black sheet metal.

Unlike the previous model, it includes phase-controlled current adjustment, making it particularly suitable for delicate work on thin materials, small-diameter rods, and stainless steel sheets. It also features power factor control cosϕ for optimized energy management.

As with the previous model, the welding force is adjustable on a daN scale, and the additional lower arm fitting provides a wider arm opening. The transformer is insulated in Class F and tested at 4000V AC. For specific requirements, the (P) version is available, allowing pulsation-controlled welding time settings.
