Product Introduction:
Unlike traditional single-head manual spot welding machines, this dual-head capacitor discharge projection welding machine achieves a comprehensive upgrade in the welding of clamp products. Traditional welding machines require manual positioning and are prone to missed welds and offset welds, whereas this equipment automatically arranges and feeds the buckles through left and right vibratory bowl feeders, so workers only need to place the ring and both sides are welded automatically. Adopting capacitor discharge technology, it is more energy-efficient than traditional AC welding machines, produces minimal spatter, and requires no secondary grinding. The left and right independent cylinders press down in sequence, avoiding workpiece deformation caused by simultaneous dual-head pressing. From manual alignment to automatic feeding, from single-point manual operation to dual-head stepwise automatic projection welding, this equipment uses the power of non-standard automation to solve the three major problems of labor shortage, low efficiency, and poor quality in ring-shaped part welding.
Features:
1.“One machine replaces two”: The dual welding head design completes welding at both ends in a single clamping, effectively integrating two single-head welding machines while eliminating one handling and realignment step, delivering an extremely high return on investment.
2.Labor savings: One operator and one machine can complete work that previously required two to three people to coordinate (one person handling small parts, one handling large parts, and one welding), significantly reducing the company’s labor cost expenditure.
3.Electricity savings: The capacitor power supply charges and then discharges instantly, so it does not need to continuously consume high power like AC welding machines. Overall energy consumption is greatly reduced, saving a considerable amount in electricity costs over long-term operation.
4.No grinding, lower consumption: The spatter-free characteristic means there is no need to purchase additional grinding tools and consumables, and the labor and time costs of the grinding step are also eliminated, directly reducing overall manufacturing costs.
5.Enhanced quotation competitiveness: The production model of high quality, high efficiency, and a low defect rate gives your clamp products stronger cost and delivery advantages in the market, making it easier to win large orders.
Welding Test:


Welding Workpiece: Built to handle everything from tabbed steel clamp rings to pipe hoops, exhaust clamps, hose clamps, pipe clamps, tab clamps, metal fastening rings, and U-clamps, this versatile dual-head welder is a perfect fit for your factory floor. By applying a step-by-step capacitor discharge projection welding technique to carbon steel, galvanized steel, and stainless steel components with custom stamping tabs, it completely eliminates the thin-wall welding headaches of thermal deformation and excessive spatter. This makes it an incredibly reliable choice for mass-producing hardware fasteners, automotive parts, home appliances, and pipeline components.
Detailed Images:

Dual independent welding joints and upper and lower electrodes: Double-end welding in one setup reduces manual handling time; long-life high-conductivity electrodes lower your electrode replacement consumable costs.

Pneumatic-hydraulic intensifier cylinder: High-pressure compaction prevents cold welds with an extremely high first-pass yield, saving you the material and time costs of rework and re-welding.
.

Left and right double vibration discs and feeding mechanism: Fully automatic feeding replaces a dedicated worker for picking small parts, significantly reducing labor costs and improving production cycle times.

Energy storage welding control box: Millisecond discharge saves significant electricity, minimizes spatter to save secondary grinding labor costs, and perfectly eliminates scrap losses caused by deformation.
