Digital tube accurate display and encoder based regulation provide precision and stable control. Using an encoder instead of a potentiometer delivers longer life and more reliable performance. Easy to install on machine casings. The board uses a double sided welding design with a compact, optimized component layout for straightforward mounting and integration. Flexible welding control. Adjustable single and double pulses, spot welding counting, synchronous triggering, and poweroff saving for consistent results across tasks. Power handling options. 41A thyristor version suitable for loads under 1000W; 100A thyristor version suitable for loads under 3000W. Built for reliability and durability. Compact board construction designed to withstand regular use in spot welding applications. Applications and use scenarios Battery pack assembly and tab welding on Liion cells, where precise pulse control improves weld quality and reduces damage. Small metalworking and jewelry fabrication requiring accurate spot welding with repeatable results. Electronics assembly and PCB related welding tasks such as tab or foil welding where stable performance and compact installation are advantageous.
