Product Description

Pneumatic 3 Phase 100 KVA Lever Lock Ring Spot and Projection Welding Machine

Video Demonstration

Product Overview

This pneumatic 3-phase 100 KVA lever lock ring stationary spot and projection welding machine is engineered for high-efficiency resistance welding of steel drum lever lock rings and similar sheet metal components. It is particularly well suited for workpieces with galvanized or chrome-plated surfaces, delivering consistent electrode pressure and controlled welding current for stable, repeatable spot and projection welds.

The machine integrates a rigid host frame, pneumatic transmission mechanism, welding positioning fixture, secondary circuit, welding transformer, welding controller, and water/gas circuit system. Available in 100–250 KVA rated capacity configurations, this stationary welding system can be customized for different workpiece dimensions and production line requirements.

Key Technical Advantages

Heavy-Duty Frame for Stable Welding

The tree-style, all-steel machine frame is impact resistant, earthquake resistant, and designed for high rigidity. Reinforcing ribs welded into the rack minimize deformation during welding, ensuring stable weld quality and safe manual operation.

Precision Linear Guide Electrode Movement

The upper electrode moves vertically along a linear guide with high repeated positioning accuracy, ensuring each welding point is placed exactly where required for consistent joint quality.

Fast-Acting Pneumatic System

Electrode pressurization is smooth and rapid, using an aluminum alloy cylinder, low-damping sealing rings, and a pilot high-flow solenoid valve. This provides fast response and sensitive follow-up performance for high-speed multi-spot welding operations.

Accurate Welding Pressure Regulation

An electrical proportional valve allows precise adjustment of welding pressure, helping to maintain uniform weld nugget formation even when workpiece thickness or surface conditions vary.

Insulated Secondary Circuit for Safe Operation

The secondary-side circuit uses a pressurized cylinder seat and upper-arm insulation method, allowing direct fixture installation and welding work on the lower seat without short-circuit risk. The design is simple, practical, and operator friendly.

Water-Cooled Energy-Efficient Welding Transformer

The main welding circuit uses a fully water-cooled resistance welding transformer and rectifier, providing strong output power while reducing energy loss. Air and water pressure switches with alarms prevent water shortage or gas-related welding faults, protecting both the equipment and the operator.

Applications

Industry	Typical Workpiece	Welding Mode
Steel Drum Manufacturing	Lever lock rings and drum body components	Spot & Projection Welding
Sheet Metal Industry	Galvanized / chrome-plated sheet metal assemblies	Multi-Spot Welding
Metal Containers & Barrels	Lock rings, brackets, and reinforcing plates	Spot Welding
Custom Metal Fabrication	Stamped or pre-formed steel components	Projection Welding

Working Principle

This stationary spot and projection welding machine uses a 3-phase resistance welding transformer to deliver high secondary current through the electrodes. The workpiece is clamped between the upper and lower electrodes under pneumatic force, and current passes through the contact point to generate resistance heat, fusing the metal surfaces together. In projection welding mode, the current concentrates on pre-formed projections for a stronger, more localized weld. A synchronized welding controller manages pressure, current duration, and electrode movement, while the fully water-cooled secondary circuit ensures stable output during continuous production.
