Overview
The TECNA 7018 and 7020 hand held Spot Welders are 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 both units enabling a range of applications.
The 7020 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. The 7913 is a 3 Phase,
water cooled, hand held Spot Welder designed for heavy duty body repairs and light production work.
