FAQ
- What's the cylinder size you want to produce?- It's better to provide the cylinder drawing.- What's the daily capacity you want to attain?

| Weight | 600KG |
Each set is capable of welding up to 350 LPG cylinders per hour (approx. 360 pcs/8hrs per set as noted), with a single-pass MIG circumferential weld completed in about 60 seconds.
The system uses high-speed pulse MIG welding (Panasonic welding sources such as YD-350GL4 and 500GS are used in various modules) with a single-pass seam welding configuration and seam-vision/video tracing for automatic tracking.
The line is designed to run φ1.2 mm solid core welding wire and welding power units are rated for a 100% duty cycle at 350 A to support continuous high-demand operation.
Yes. Dimensions, voltage, and certain configuration details can be customized to meet your site requirements and local electrical standards.
The system includes a double tracking system, conveyor and chain handling mechanisms, mechanical arms for conveying cylinder halves, and automatic seam-vision/video tracking for precise circumferential weld alignment.
Although optimized for LPG gas cylinder circular seams (socket, handle, base ring, circumference), the system can be applied to other industrial circular seam welding tasks that match the machine's size and process capabilities.
Typical requirements include appropriate three-phase electrical supply (customizable voltage), compressed air (0.4–0.8 MPa for some semi-auto machines), circulating cooling water systems for weld torches, adequate floor space and load-bearing foundation (machine set weight example: 40,000 kg), and safe material handling access.
Yes. The company provides overseas installation and commissioning services, sending skilled engineers to assist with on-site setup, calibration and to help the customer run the machine smoothly.
Main consumables are welding wire (φ1.2 mm), shielding gas, contact tips/nozzles and coolant for water-cooled torches. Regular maintenance includes torch and tip replacement, wire feeder checks, cooling system maintenance, PLC/control backups, and routine lubrication and inspection per service schedule.
Follow applicable LPG cylinder standards and local regulations: visual inspection, dimensional checks, non-destructive testing (e.g., leak test, pressure test), and adherence to weld quality parameters. The automated vision tracing reduces human error but final testing is mandatory for safety compliance.
Full-automatic modules use Mitsubishi PLC control units and Pro-face color touch screens for operator interface; welding sources and vision tracking are integrated for automated parameter control and seam following.
According to supplied comparisons, MIG delivers higher capacity (approx. 360 vs. 240 pcs/8hrs per set), single-pass welding (vs. two paths for SAW), and can save about 40% in power and wire consumption, plus MIG systems incorporate auto laser/video tracing which SAW lacks.
The supplier provides operator and maintenance training during commissioning, technical documentation, and after-sales support. Skilled engineers are available for overseas installation and troubleshooting to ensure timely ramp-up.
Lead time depends on configuration and order size; because many parts are machined in-house the supplier aims for timely delivery. Standard warranty and spare parts policies vary—request specific terms at inquiry to get details on warranty duration, spare parts kits and service agreements.
To recommend the proper machine, provide cylinder dimensions and technical drawings, desired daily/shift capacity, preferred voltage and local electrical specs, and any special process or regulatory requirements.
