(40 A) Soldering Iron Control Board, Time and Current Control Panel with Digital Display

The control panel of this spot welder is independently developed for DIY or simple resistance welding. The silicon-controlled fault activation principle is adopted to adjust the time and current to achieve the desired welding result.

Equipped with a digital display, you can visually monitor the time and current, making it easy to use.

High and low voltage are isolated by the optical coupler, making it safer to use.

Use the high-precision potentiometer unit to ensure reliable and convenient input. The reliable zero-crossing detection circuit guarantees the accuracy of the SCR fault detection.

Two models are available: 40A or 100A.
