System Overview & Architecture

Engineered for high-precision industrial spot welding, this machine features a high-performance single-chip CPU control architecture. The split-type modular design separates the main power unit from the welding head, complemented by a high-rigidity gantry frame.

Split Structure: Massive working clearance for versatile battery pack configurations.
Real-Time QC: Audio-visual alarm instantly triggers upon detecting current abnormalities.
High Consistency: Ultra-fast polarity switching ensures identical energy distribution across both weld spots.

01. Performance Features

High-Performance Microcomputer Control Powered by an advanced MCU/CPU control core, specifically developed for demanding industries with strict welding quality standards.	30-Group Parameter Recipe Storage Stores up to 30 custom welding specifications in non-volatile memory, enabling instant recall and rapid production switching.
Real-Time Quality Monitoring & Alarm Integrated current monitoring automatically triggers sound-and-light alarms when output fluctuates beyond threshold ranges.	Dual-Pulse Discharge Mode Features 2-stage pulse output to accommodate complex materials, surface coatings, and multi-layer welding requirements.
Microsecond Fine Adjustment & Polarity Switching Pulse widths (Pulse 1 & Pulse 2) are precisely adjustable. High-speed polarity switching guarantees uniform size for twin weld nuggets.	Grid Voltage Regulation & Anti-Interference Equipped with electronic stabilization and RFI/EMI shielding to ensure constant energy output even during mains power fluctuations.
Electrode Maintenance Counter Built-in weld spot counter presets maintenance thresholds, automatically alerting operators for electrode grinding or replacement.	Flexible Mechanical Architecture High-rigidity gantry frame design accommodates large battery packs. Flexible support for pneumatic operation and foot pedal triggers.
