Sessleger -D01 Spot Welder Control Board, DIY, 40 A

Description

• High- and low-voltage circuits are isolated by an optocoupler for safer operation.
• An industrial STM8 single-chip microcomputer serves as the main control core.
• A high-precision single-turn potentiometer is used for time and input-current adjustment.
• The power and foot-control lines use screwless terminal blocks for convenient, reliable connections.
• The board power, status, pin, trigger indicator, and operating status are clearly visible.

A reliable zero-crossing detector is designed to ensure precise phase shifting of the silicon-controlled rectifier. The controller is compatible with 40 A100 A thyristors. The digital control interface displays the currently set time and current. Time input: 150 unit cycles, with one cycle equal to 20 ms. Current input: 30%99%. Product name: spot welder control panel. Model: -D01. Thyristor current: 40 A. Installation: Keep the motherboard away from the large transformer; do not install it on the transformer, as large transformers produce electromagnetic interference. Note: This spot welder control board is independently designed for DIY users or simple resistance-welding and control equipment. Spot welding is achieved by adjusting time and current based on the thyristor phase-shift triggering principle. Color: red. Material: PCB and metal. Package includes: 1 control panel, 1 display panel, 1 connection cable, and 2 twist caps. Only the items listed above are included; other products are not included. Note: Light reflections and different monitors may cause the item's color to vary slightly from the actual product. Measurements may vary by 13 cm.
