Certified & Reliable Gantry Structure: Features an ISO/CE-compliant, high-rigidity gantry frame that ensures stability and safety under prolonged, high-duty operation. Equipped with multiple independently pneumatic-actuated square electrodes, each with individually adjustable force and stroke, enabling the uniform, synchronous welding of multiple spots on large workpieces for multiplied efficiency.
-
Precise Adjustable Welding Force & Motion: Electrodes are pressurized by air cylinders for convenient and accurate force adjustment. The descent and ascent speeds of the pressure head are independently and infinitely adjustable, achieving cushioned contact with the workpiece. This effectively mitigates impact, protects the workpiece, reduces noise, and enhances weld quality.
-
Intelligent & Stable Welding Control: The main circuit utilizes high-power thyristor components for strong, stable, and reliable output. A microprocessor-based fast-response touch controller provides fully digital control and an intuitive interface. Its unique automatic detection and compensation functions effectively prevent defects like cold welds and insufficient fusion.
-
Efficient & Safe Human-Machine Interaction: Operation is controlled by a foot switch for high productivity and low labor intensity. The secondary conductor employs an upper insulation method for safe and reliable insulation. The overall design complies with ergonomic and safety standards, ensuring support for continuous automated production
