The Dual Pulse Spot Welder Series are capacitive discharge power supplies (CD welder) that have been designed specifically for precision resistance spot welding applications such as battery pack welding. They are controlled by microprocessor, store multiple weld schedules, and provide consistent weld energy to the parts being joined. MIYACHI UNITEK’s dual-pulse spot welders deliver high-peak energy with fast rise times. This is particularly important when welding highly conductive materials such as copper and brass. The control system provides a highly stable output, independent of line voltage fluctuations which results in repeatable energy delivery from weld to weld. The short weld times of the Dual Pulse Series result in minimal deformation and marking to parts.

Dual Pulse function eliminates surface inconsistencies
Microprocessor controlled
Optional built-in weld monitor
Up to 128 programmable weld schedules
