Unimig TECNA 7900 Handheld Spot Welder 

• A synchronous built-in electronic timer with more than 65 cycles
• The built-in transformer with F-class insulation ensures a superior life-span
• Designed to use a wide range of spot-welding arms and electrodes

Synchronous Electronic Timer

A built-in synchronous electronic timer with SCR provides a range of 2 to 65 cycles. The compensation circuit will only start the timer once there is a proper current passage, allowing the spot welder to work on painted surfaces and oxidised or black sheets.

Multiple Arm Sets

Comes with 125mm arm set, with extra arm sets available for larger openings and a large range of welding applications.

Force Adjustments

Force adjustment scaled in daN.

Built to Last

The transformers are coated with F class insulation material, which doesn't dry out or turn brittle, tested at 4000 volts, extending the lifespan of the spot welder.
