Electric Spot Welding Machine
Select DN1 resistance spot welding from the overlap, electrode reach and accepted joint—not rated capacity alone.
- Models
- DN1-16 / 25 / 40
- Listed voltage
- 220 V
- Listed duty
- 20%
Approve the overlap and electrode access
Localized joints
Resistance spot welding joins at discrete electrode locations. Share overlap, reach and finished joint requirements; do not treat isolated spots as a continuous sealed seam.

The supplied Welding Size values use diameter notation. They must not be interpreted as universal sheet-thickness ratings. Confirm material and joint geometry by a sample trial.
Choose capacity with the installation
| Check | Reason |
|---|---|
| Rated capacity and input current | Review the selected model with the site electrical supply. |
| Arm reach and access | The electrodes must reach the planned spot positions. |
| Duty cycle | The table lists 20%; confirm its rating conditions and production cycle. |
| Joint sample | Approve weld locations, surface condition and the agreed inspection. |
Questions to settle before ordering
Does spot welding make a continuous seam?
It makes localized welds; a continuous joint requires separate process review.
Is Welding Size a sheet capacity?
The table uses diameter notation. Confirm its meaning and actual joint rating.
How should I choose rated capacity?
Review material, joint sample, duty conditions and electrical supply.
What limits access?
Arm reach, workpiece shape and electrode position need checking.
What should I send for a quote?
Material, overlap drawing, spot positions, production cycle and electrical supply.
