41A Thyristor version for transformers up to 1000W - Precise digital readout and encoder-based regulation: more accurate and stable control with no potentiometer wear, contributing to longer life. - Double-sided welded PCB with a thoughtfully redesigned component layout: integrated on a board that is easier to mount in a machine housing. - Flexible operation and memory features: selectable single or double pulse modes, spot weld counting, synchronous triggering, and power-off storage. Use scenarios - Industrial spot welding on small to medium assemblies: ideal for applications using transformers under 1000W, where repeatable energy delivery and reliable control are important. - Equipment upgrades and retrofits: upgrade existing welding stations to achieve tighter process control, longer component life, and easier installation on machine frames. - DIY and prototyping in automated setups: compact, easy to mount control board that provides reliable pulse control and energy storage for experimental weld rigs.
