This five-head projection resistance spot welder is engineered for high-volume sheet metal fabrication, delivering simultaneous multi-point welds on stainless steel, aluminium, and other alloy materials. The gantry-style frame combines a pneumatic actuation system, water-cooled welding transformer, and independent head controls, allowing production lines to balance speed with repeatable joint quality across automotive, home appliance, and metal mesh applications.
Unlike single-point units, this machine lets operators run all five heads in sequence or independently, cutting cycle time on large panels while keeping each weld parameter adjustable. With rigid structural design and precision-guided electrodes, it maintains consistent electrode force and alignment, helping fabrication shops reduce rework and meet tighter production schedules.
Each of the five welding heads can operate simultaneously, progressively, or separately, granting operators the flexibility to adapt weld patterns to different workpiece geometries without slowing down the production cycle.
The single-column body is reinforced with multiple internal ribs and precision-machined mounting surfaces, keeping structural deformation minimal under repeated electrode force and supporting stable weld quality over long shifts.
Aluminium-alloy cylinder barrels with low-friction sealing rings and a high-flow pilot solenoid valve deliver rapid, smooth electrode travel, enabling high dot-per-minute rates without compromising follow-up pressure accuracy.
An electrical proportional valve allows precise adjustment of welding force, so operators can fine-tune settings for thin aluminium sheets versus thicker stainless steel panels, improving nugget consistency across mixed material runs.
The fully water-cooled resistance welding transformer and rectifier maintain strong output while reducing heat buildup, extending duty cycle and lowering energy consumption during continuous multi-shift operation.
Built-in pneumatic and water pressure switches with alarms prevent operation under low coolant or insufficient air pressure, safeguarding both the equipment and the quality of the weld in progress.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Sheet Metal Processing | Cabinets, enclosures, brackets | Multi-point projection welding |
| Home Appliance Manufacturing | Washing machine shells, refrigerator panels | Simultaneous five-head welding |
| Automotive Parts | Seat components, mounting plates | Programmable head sequence |
| Metal Mesh Fabrication | Wire mesh panels, expanded metal | Individual head control |
The machine uses pneumatic pressurization to drive upper electrodes against workpieces positioned on a lower seat. A welding transformer sends high current through the electrodes, creating localized resistance heat at projection points until the material coalesces into a solid nugget. Built-in coolant circulates through the transformer and electrode holders to manage heat, while an auxiliary gas reservoir stabilizes pressure fluctuations for consistent joint formation.

Yes, it handles both materials when the correct projection geometry, electrode pressure, and current settings are applied. The proportional valve and adjustable head sequence give operators the range needed to switch from softer aluminium sheets to harder stainless steel panels.
The unit is supplied with five heads that can operate together, in a staggered sequence, or as independent stations. This flexibility supports both high-speed repeat patterns and custom joint layouts on larger panels.
Standard configuration runs on a three-phase 380V AC input. Please connect the unit to a dedicated line with adequate capacity since these models draw significant current during continuous welding cycles.
Water cooling is required at roughly 20 L/min to protect the transformer and electrode holders. The built-in water pressure alarm alerts the operator if flow drops below a safe threshold.
Yes, the auxiliary cylinder design provides continuous stroke adjustment up to 80 mm, so operators can match the head travel to varying part heights without having to disassemble the pressurization assembly.
