The TECNA® 7900 Handheld Spot Welder is designed to be lightweight, reliable and simple to operate. It is built for users who are in the smash repair and sheet metal industries. It features a synchronous built-in electronic timer with more than 65 cycles, to spot-weld effectively on oxidised sheets, surfaces with paint residue, or on black sheets. The TECNA® 7900 also has a built-in transformer with superior life-span thanks to its F-class insulation material that won’t dry out or turn brittle. The unit can fit a wide range of spot-welding arms and electrodes, making it useful for a range of applications.
