-
Customized Long-Arm Design
Features an extended welding arm tailored for special-shaped workpieces like fan guards and protective cages. This design provides extended reach and access, solving welding challenges in confined or complex geometries where standard machines cannot operate.
-
Precise & Adjustable Pneumatic System
The upper electrode is actuated by an air cylinder for convenient and precise pressure adjustment. An integrated air reservoir helps buffer and stabilize welding pressure, ensuring consistent force output for each weld.
-
Flexible & Efficient Electrode Stroke
The upper electrode moves vertically with independently and smoothly adjustable working and auxiliary strokes. The lower electrode height is vertically adjustable, allowing for quick setup and adaptation to workpieces of varying thicknesses.
-
Fast Response & Smooth Operation
Employs a direct-acting solenoid valve for fast response, significantly increasing the cycling speed. The descent and ascent speeds of the pressure head are infinitely adjustable, effectively cushioning impact on the workpiece and reducing operational noise.
-
Stable & Reliable Electrical Design
The secondary circuit utilizes an upper insulation configuration for stable and reliable insulation. The main power circuit is built with a fully water-cooled, high-power thyristor rectifier module, delivering strong and stable output for consistent welding performance.
-
Durable & Visual Cooling System
All waterway components are constructed from copper and stainless steel for corrosion resistance and longevity. A visual flow indicator allows for easy monitoring of coolant circulation, simplifying routine maintenance.
-
Efficient & Simple Human-Machine Interface
Operation is controlled via a foot switch, enabling fast cycling and high production efficiency while significantly reducing operator labor intensity
