Spot Welding Machine Overview
This page brings your DN-F foot-operated and DN-P pneumatic spot welding lineup into one place. Every model below shows three useful comparison specs, and every product link opens in a new tab.
The range covers light-duty foot-operated spot welding, pneumatic production welding, and higher-capacity structural models for thicker sheet and heavier industrial work.
Three clear spot welding machine families for faster comparison
The lineup is grouped the way buyers usually narrow it down in practice: foot-operated DN-F models first, then pneumatic DN-P production machines, then higher-capacity structural models for thicker low carbon steel work.
3 models
Direct foot-control spot welders for light-duty to production-oriented sheet work with simpler mechanical operation.
4 models
Pneumatic models for steadier pressure, more repeatable welding quality, and stronger day-to-day shop production.
2 models
Higher-capacity spot welders for structural and thicker-section applications where output reserve and pressure matter more.
Every spot welding machine page in one overview
Each model is shown with three practical comparison specs. Use the grouped tables below to scan quickly, then open the matching product page in a new tab when you want the full machine details.
Simple foot-pedal spot welders for lighter sheet work and manual shop use
The DN-F family focuses on direct foot-operated control, timer-based spot welding, and practical sheet-metal work where simple structure and manual operation are more important than pneumatic cycle efficiency.
| Model | Welding Thickness | Rated KVA | Arm Extension | Product Page |
|---|---|---|---|---|
| DN-16FFoot-pedal spot welder for light-duty low carbon steel sheet work | 1.5 + 1.5 mm | 16 KVA | 300 mm | Open page |
| DN-25FStronger foot-operated model for general sheet metal fabrication | 2.0 + 2.0 mm | 25 KVA | 500 mm | Open page |
| DN-40FProduction-oriented foot-pedal spot welder with higher output reserve | 2.0 + 2.0 mm | 35 KVA | 360 mm | Open page |
Pneumatic production spot welders for steadier pressure and repeatable daily output
The DN-P production group is aimed at users who want more consistent pressure and more repeatable weld quality than a basic foot-operated machine usually provides. This group moves from thicker general sheet work into heavier fabrication demand.
| Model | Welding Thickness | Rated KVA | Arm Extension | Product Page |
|---|---|---|---|---|
| DN-25PPneumatic spot welder for thicker general fabrication sheets | 2.5 + 2.5 mm | 40 KVA | 500 mm | Open page |
| DN-35PEntry pneumatic model for stable daily production welding | 1.5 + 1.5 mm | 25 KVA | 360 mm | Open page |
| DN-50PMid-range pneumatic spot welder for medium-thickness sheet work | 2.5 + 2.5 mm | 50 KVA | 360 mm | Open page |
| DN-75PHeavier pneumatic model for stronger fabrication and production loads | 3.0 + 3.0 mm | 75 KVA | 460 mm | Open page |
Higher-capacity spot welders for structural and thicker-section industrial work
These higher-capacity models extend the range into structural and thick-plate applications. They are the better fit where thicker low carbon steel, stronger output reserve, and higher-pressure production work are part of the actual job.
How to guide visitors toward the right spot welding machine
Keep the buying decision simple by matching the operation method first, then the welding thickness, then the production workload and machine size.
Start with foot-pedal or pneumatic control
Choose DN-F when direct manual control and simpler structure matter most. Move into DN-P when steadier pressure and more repeatable day-to-day production welding are the priority.
Use actual low carbon steel thickness to narrow the shortlist
DN-16F and DN-25F suit lighter sheet work, DN-25P through DN-75P cover thicker fabrication demand, and DN-100P and DN-160P step into structural and heavier-section applications.
Choose by production volume and physical reach
Compare the rated KVA, arm extension, and overall machine scale before final selection. Larger pneumatic and structural models make more sense when the work is repetitive, thicker, or more production-oriented.
Verify the final material thickness, package scope, utilities, and application fit before order confirmation.
Published specifications, standard delivery scope, and accessory ratings are for reference only and may change without notice. Included electrodes, electrode arms, electrode holders, foot pedals, pneumatic components, air-service units, pressure-adjustment assemblies, cooling-water connections, control units, cables, plugs, and other accessories may vary by model, package, and destination market. Before supply, confirm the required resistance spot welding application, input power, rated capacity, duty cycle, workpiece material and thickness, arm extension, available air or cooling-water utilities, and applicable local compliance requirements for the intended application.
