DN-25F
Spot Welding Machine DN-25F (Foot-Pedal) is a 380V foot-operated resistance spot welder for general sheet metal fabrication up to 2.0 + 2.0 mm low carbon steel.
DN-25F builds on the light-duty foot-operated range with thicker sheet welding capacity, timer control, and practical shop-floor operation.
DN-25F Technical Specifications
This page presents the DN-25F model with its supplied foot-operated spot welding specifications and application data.
Foot-operated spot welding with stronger light-duty thickness capacity.
DN-25F combines simple mechanical pressurizing, timer-based control, and 2.0 + 2.0 mm low carbon steel capability for general sheet metal fabrication.
Foot lever mechanism for straightforward manual welding
The supplied DN foot-operated feature text describes a simple foot lever pressurizing structure suited to general sheet metal spot welding work.
Automatic cutoff helps stabilize weld spot quality
The timer control circuit automatically cuts welding current on schedule, reducing operator influence and improving repeatability across repeated weld spots.
Electronic timing controller with repeatable selection
The provided source text lists an electronic controller with 0.02-2 second adjustment range, with typical welding times often within 0.5 second.
Light-duty manual operation with more thickness than DN-16F
The supplied tables place this reference at 2.0 + 2.0 mm low carbon steel, making it a stronger foot-operated option for general sheet metal fabrication.
Where DN-25F fits
DN-25F serves as a stronger light-duty foot-operated option for general fabrication shops that need more thickness capacity than DN-16F.
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
- General sheet metal fabrication
- Manual resistance spot welding work
- Low carbon steel sheets at 2.0 + 2.0 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.
