This automatic double head spot welding machine is purpose-built for high-volume production of steel door panels, electrical enclosure boxes, and elevator door skins. By integrating dual electrode heads with an X/Y axis moving fixture and a single-station exchange rack, the system welds two points simultaneously and automatically repositions the workpiece between cycles, sharply increasing throughput while maintaining repeatable weld quality.
The press-type frame design delivers stable, vertical electrode force with pneumatic actuation, eliminating the need for a hydraulic station. With a compact footprint of 5250 x 3775 x 2067 mm and a welding capacity of 0.5 to 1.5 mm sheet thickness, this machine is an ideal entry-level automation solution for small and medium-sized manufacturers upgrading from manual spot welding.
A pair of copper alloy electrodes welds two points per cycle, halving the number of passes required compared to single-head machines. The vertical pneumatic pressurization ensures consistent electrode force and a stable fusion nugget on each weld.
Servo-driven screw or belt mechanisms move the fixture in the horizontal plane, aligning each welding point with the electrodes in sequence. This removes manual repositioning errors and supports multi-point welding of large panels without operator intervention.
No hydraulic pump or oil circuit means lower initial investment, reduced energy consumption, and simpler maintenance. Only a three-phase 380V supply and compressed air are required, making installation straightforward in existing workshops.
For small-batch or customized door panels, the X/Y fixture can be manually positioned using hand wheels, avoiding the cost of additional servo drives while retaining flexibility for diverse workpiece sizes.
The press-type body occupies minimal floor space, while the single-station exchange rack uses push-pull loading and unloading. The simplified mechanism lowers the failure rate and speeds up the cycle between batches.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Elevator Manufacturing | Door panels, reinforced ribs | Automatic multi-point double head spot welding |
| Security Door Production | Anti-theft door skins, stiffeners | Double head spot welding on galvanized sheet |
| Electrical Enclosures | Cabinet bodies, control box panels | Spot welding of 0.5–1.5 mm sheet metal |
| Home Appliance Fabrication | Large cabinet shells, sheet metal parts | Low-carbon steel and coated plate welding |
The operator clamps the workpiece on the fixture and activates the cycle with both hands. The X/Y mechanism automatically shifts the panel to the first welding position, then pneumatic cylinders press the upper electrodes down vertically. A thyristor switches the welding transformer primary, generating high secondary current that flows through the two electrodes and concentrates heat at the sheet contact points, forming the weld nuggets. After the weld is completed, the thyristor turns off, the electrodes retract, and the fixture indexes to the next position. The sequence repeats until all programmed points are welded, after which the panel moves into the exchange rack for unloading.

The standard configuration welds elevator door panels of 0.5 to 1.5 mm. Depending on the selected transformer model (DN(B)-100 to DN(B)-250), the maximum combined thickness ranges from 3.0+3.0 mm up to 6.0+6.0 mm for mild steel.
Yes. When configured with the intermediate frequency control box (optional), the DC output reduces spatter and heat-affected zone damage, making it suitable for galvanized sheets and coated plates while preserving the anti-corrosion layer.
Yes. The touch-screen interface stores multiple welding programs, and the X/Y fixture can be manually adjusted for custom small-batch panels. Operators recall a program and the machine automatically indexes the correct welding path.
Only a three-phase 380V power supply and compressed air are required. There is no hydraulic station, so installation, maintenance, and running costs are considerably lower than for hydraulic alternatives.
We offer free sample welding and process design services so you can physically verify weld quality and cycle time for your specific door panel before finalizing the machine configuration.
