DN-25P Technical Specifications
This page presents the DN-25P model with its supplied spot welding specifications and application data.
High-output spot welding setup for thicker sheet fabrication.
DN-25P is positioned for thicker low carbon steel spot welding with dependable current control, practical timing adjustment, and general fabrication use at 380V.
2.5 + 2.5 mm sheet welding with dependable current control
DN-25P is presented for thicker sheet spot welding at 380V, with strong output for low carbon steel work up to 2.5 + 2.5 mm.
Automatic current cutoff for more consistent spot welding
The supplied feature text states that timed current cutoff reduces human influence and helps stabilize weld spot quality during repeated work.
Electronic timing controller with 0.02-2 second range
The supplied feature section lists a 0.02-2 second electronic timing controller for repeatable welding time selection.
2.5 + 2.5 mm low carbon steel spot welding capacity
Across the supplied data, DN-25P is presented for thicker sheet welding up to 2.5 + 2.5 mm low carbon steel.
Where DN-25P fits
DN-25P sits in the range as a higher-output model for thicker sheet work and daily fabrication tasks.
Service life statement provided in source text
The supplied source content states: main unit service life 12-20 years, described as five times longer than inverter welder life. This is preserved as a source note only.
Typical work scope from supplied data
- Thicker sheet metal spot welding
- General sheet metal fabrication
- Low carbon steel sheets at 2.5 + 2.5 mm listed thickness
Select foot-operated or pneumatic resistance spot welders by welding thickness, pressure method, and production demand.
This spot welding lineup covers DN-F foot-operated models for straightforward manual sheet work and DN-P pneumatic models for more stable pressure, repeatable production welding, and higher-capacity structural applications.
DN-F Foot-Operated Range
- DN-16F, DN-25F, and DN-40F cover simple mechanical operation for light-duty to heavier sheet-metal spot welding.
- These models suit users who prefer direct foot control, straightforward setup, and lower-volume workshop production.
- Choose this group when manual operation and simpler structure are more important than pneumatic cycle efficiency.
DN-P Pneumatic Production Range
- DN-25P, DN-35P, DN-50P, and DN-75P cover pneumatic spot welding for thicker sheet, steadier pressure, and more repeatable daily production.
- Pneumatic models are better suited to regular shop-floor use where welding consistency and operating efficiency matter more.
- Select this group when stable pressure control and higher production demand are part of the working process.
Structural And High-Capacity Models
- DN-100P and DN-160P extend the range for industrial structural and thicker-section spot welding applications.
- DN-160P keeps both supplied thickness references visible because the selection guide and parameter table are not identical.
- Confirm actual thickness requirement, arm extension, rated capacity, and utilities before final model selection.
Verify package scope and application suitability 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.
