Established in 1975, WPI Taiwan provides resistance welding equipment and engineering support, with customizable machine configurations to suit different workpiece sizes, throat depths and welding requirements.
Common Production Challenges in Stationary Spot Welding
Manufacturers choosing a stationary spot welding machine need to consider more than rated power. Workpiece dimensions, electrode access, required welding force and production volume all affect machine selection.
Selecting the right machine structure and configuration helps manufacturers align welding capability with actual production needs.
Machine Configurations for Different Welding Requirements
WPI Taiwan offers stationary resistance spot welding machines in different capacities and structural configurations to suit a range of industrial applications.

Pneumatic Spot Welding Machine (Stationary Type)
The stationary type design provides a stable vertical electrode arrangement for repeatable spot welding and, when properly configured, projection welding applications. It is a practical option for sheet metal components, electrical enclosures, appliance parts and other workpieces that can be positioned within the machine throat.
Machine capacity, throat depth, electrode stroke and tooling should be selected according to the workpiece dimensions and welding requirements.
Pneumatic Rocker Arm Spot Welder
The rocker arm design provides additional workpiece access and clearance for parts that are difficult to position in a conventional stationary type spot welding machine. Depending on the model, a two-stage pneumatic cylinder provides a wider opening stroke for workpiece positioning, followed by a shorter welding stroke for electrode approach and welding.
This configuration is suitable for cabinets, box-shaped assemblies, drawers and other parts requiring deeper access or greater clearance. Arm geometry, throat dimensions and electrode reach should be confirmed for each application.
Frequently Asked Questions About Stationary Spot Welding Machines
What is the difference between a stationary type spot welding machine and a rocker arm spot welder?
A stationary type spot welding machine uses a vertical press arrangement and is suitable for workpieces that can be positioned within its throat. A rocker arm spot welder provides a different arm structure and can offer greater access for deeper or more complex workpieces. The appropriate choice depends on workpiece geometry and electrode access.
How do I choose the right spot welding machine capacity?
Machine capacity should be evaluated based on material type, sheet thickness, number of layers, joint design, and required electrode force and production rate. Providing a workpiece drawing or sample details helps WPI Taiwan evaluate suitable machine capacities and configurations for your application.
Can WPI customize the machine for my workpieces?
WPI Taiwan can evaluate machine dimensions, throat depth, arm configuration and electrode tooling according to the application. Please provide workpiece drawings or photos, material and thickness information, weld locations and expected production volume for an initial technical review.
Can a stationary spot welding machine perform nut and bolt projection welding?
Suitable stationary spot welding machine can be configured for nut and bolt projection welding, depending on the workpiece, projection design and required tooling. The electrode arrangement and machine capacity should be confirmed for the specific application.

Common Production Challenges in Stationary Spot Welding
Manufacturers choosing a stationary spot welding machine need to consider more than rated power. Workpiece dimensions, electrode access, required welding force and production volume all affect machine selection.
- Inconsistent Weld Results: Stable electrode force, suitable welding parameters and proper electrode contact are important for repeatable weld quality.
- Limited Access to Welding Points: Standard press-type machines may not provide sufficient clearance for deep or obstructed areas inside cabinets and box-shaped assemblies.
- Different Workpiece Sizes: Throat depth, arm configuration and electrode stroke should match the dimensions and geometry of the parts being welded.
- Nut and Bolt Projection Welding: These applications may require dedicated electrodes and tooling designed around the projection position and workpiece positioning.
- Continuous Production Requirements: Transformer capacity, cooling provisions and machine duty cycle should be evaluated against the intended production rate.
Selecting the right machine structure and configuration helps manufacturers align welding capability with actual production needs.
Machine Configurations for Different Welding Requirements
WPI Taiwan offers stationary resistance spot welding machines in different capacities and structural configurations to suit a range of industrial applications.
- Pneumatic Electrode Force: Pneumatic actuation provides controlled electrode clamping for repeatable welding cycles when properly configured.
- Machine Capacity and Power Supply Options: AC and inverter-based (MFDC) options are available across applicable models. Capacity should be matched to the material, thickness, joint design and required production rate.
- Throat Depth and Electrode Configuration: Machine dimensions and electrode reach can be evaluated according to workpiece size and welding-point location.
- Dedicated Projection Welding Tooling: Suitable electrode holders and tooling can be selected for nut and bolt projection welding applications.
- Cooling Options: Cooling requirements should be matched to the selected machine, electrode configuration and production duty cycle.
