PHD-21Q Mid Force Pneumatic Weld Head
The PHD-21Q Mid Force Pneumatic Weld Head is a premium pneumatic welding actuator engineered for medium-load resistance spot welding. It delivers stable, adjustable and consistent mid clamping force, with smooth pneumatic operation and fast response speed. Built with high-rigidity frame and precision linear guide structure, it ensures precise electrode alignment, uniform pressure output and highly repeatable welding results.
Constructed with wear-resistant materials and a durable air cylinder, the weld head features long service life, stable continuous operation and minimal maintenance. It is fully compatible with mainstream inverter spot welders and bench resistance welders, easy to install and suitable for manual stations as well as automated production lines.
Widely applied for welding lithium battery tabs, nickel strips, copper foils, electronic components and small precision hardware parts. The PHD-21Q is a cost-effective, reliable choice for daily batch precision welding production.
