Industrial Point Pneumatic 100Kva Stationary Spot Welder Resistance Welding Machine for Shock Absorber

Video Demonstration

Product Overview

This stationary spot welder is a 100 KVA pneumatic resistance welding machine engineered specifically for welding the convex ring of shock absorber oil storage cylinders. It integrates a rigid main frame, pneumatic transmission, horizontal welding mechanism, secondary circuit, water-cooled welding transformer, and advanced welding controller into one reliable system, delivering consistent projection welding performance for automotive and industrial component manufacturers.

Designed for high-volume production environments, this fixed-type spot welding machine supports rated capacities from 100 to 250 KVA and is available in 380V, 220V, and 440V configurations. With a maximum welding thickness of 6.0+6.0 mm and a duty cycle of 50%, it offers the rigidity, repeatability, and process stability required for demanding shock absorber assembly lines and metal fabrication applications.

Key Technical Advantages

Rigid Tree-Type Frame for Dimensional Stability

The machine body is designed with impact resistance, earthquake resistance, and high rigidity. Multiple reinforcing ribs welded inside the frame minimize deformation during continuous welding, ensuring consistent weld quality and safe manual operation over long production runs.

Precision Linear-Guide Electrode Movement

The upper electrode travels vertically along a linear guide with high repeat positioning accuracy, ensuring accurate weld points on every cycle. This precision directly reduces rework and improves the overall first-pass yield of your welding operation.

High-Speed Pneumatic Pressurization System

An aluminum alloy cylinder with low-damping seals and a pilot high-flow electromagnetic directional valve provides smooth, rapid electrode pressurization. The sensitive follow-up performance enables extremely high spot welding speeds, boosting production throughput.

Adjustable Welding Pressure via Electric Proportional Valve

An integrated electric proportional valve allows precise adjustment of welding pressure, giving you fine control over weld nugget formation. This ensures consistent joint strength across different material thicknesses and reduces process variability.

Safe Insulation and Reliable Secondary Circuit

The secondary circuit adopts pressurized cylinder seat and upper arm insulation, allowing direct installation and welding on the lower seat without short-circuit risk. This simple, practical design enhances operator safety and reduces equipment downtime.

Water-Cooled Transformer with Safety Alarms

A fully water-cooled resistance welding transformer and rectifier deliver strong output power with energy-saving efficiency. Built-in air pressure and water pressure switches with alarms prevent dry running or gas shortages, protecting the equipment and extending service life.
