The TECNA 7900 hand held Spot Welder is light weight, reliable and simple to operate units for the smash repair and sheet metal fabrication industries. There are a variety of arms available for this unit enabling a range of applications. The 7900 has the added advantage of coming standard with a timer. A compensation circuit starts the timer only when there is a proper range of current which allows welding on oxidised sheets or materials with a painted surface.
