A triple protective structure shields the cylinder from weld spatter contamination. Special rod surface finishing protects the piston rod, a coil scraper removes adhered spatter, a soft wiper provides secondary cleaning, and a dust seal prevents contaminant ingress. This spatter-resistant design extends service life in high-power welding environments. The clamp requires no hydraulic system, operating on standard compressed air at 2 to 5 Bar greatly simplifying installation compared to hydraulic clamping systems.
The mechanical locking design delivers three times the clamping force compared to general pneumatic cylinders of equivalent size, allowing a smaller footprint and reduced fixture weight. Minimal clamping force combined with high mechanical holding force reduces workpiece distortion while providing sufficient strength to withstand welding reaction forces and thermal deformation. The clamp can be integrated with an auto switch for action confirmation in automated systems; magnetic field resistant models are recommended for welding applications. Standard Arms are available, see Accessories.
WCG High-Power Welding Link Clamps are available in four sizes: WCG1000-2GCT (0.9 kN clamping, 0.8 kN retention), WCG1600-2GCT (1.6 kN clamping, 1.5 kN retention), WCG2500-2GCT (2.5 kN clamping, 2.5 kN retention), and WCG4000-2GCT (3.9 kN clamping, 4.5 kN retention). Maximum operating pressure is 5 bar across all sizes. Patented design. Other sizes and stlyes available. Made in Japan.
