The high-performance submerged arc stud welding machine BMK-12W, produced by Germany's SOYER (Soyer) Company, boasts stable performance and excellent welding quality. This product is directly imported in its entirety from Germany's SOYER Company by Shanghai Yueshi Welding Technology Co., Ltd., and is not assembled or produced domestically.
This product is highly suitable for bolts with diameters ranging from 5 to 12mm, and offers welding methods such as short-cycle unprotected arc welding, long/short-cycle gas shielded arc welding, and long-cycle ceramic ring shielded arc welding.
The product is widely used in:
Automotive and motorcycle manufacturing industry(Representative Companies: Wuling Motors, JAC Motors, CRRC Corporation Limited, etc.)
Non-stick aluminum cookware manufacturing(Representative Companies: Supor, ASKA, etc.)
Ring Main Air-Insulated SubstationManufacturing(Representative Companies: Siemens, etc.)
Handrail Elevator Manufacturing Industry(Representative Companies: Otis Elevator, Mitsubishi Elevator, etc.)
Structural Features:
The equipment is robust and durable, resistant to damage, and capable of withstanding harsh working conditions and prolonged periods of high-intensity operation.
Built-in high-power cooling fan ensures stable operation for extended periods.
Highly secure with all EU strict certifications and tests passed.
The welding gun and ground cable interface features a non-symmetric design to prevent reverse insertion.
Dual ground wire cable interface, offering users higher freedom of use.
Equipped with a feedback-type power switch, it automatically returns to the 0 position in case of power failure (power outage/power phase loss), ensuring safe operation.
Operation Features:
Built-in multi-language menu, adjustable in English, French, German, Italian, and more with special function keys.
The equipment panel features status indicator lights, which provide detailed information about the equipment's operating condition and serve as a guide during operation.
Large LCD panel, displaying detailed values of various welding parameters of the equipment. Adjust welding parameters freely with the 4 physical buttons on the panel.
Standard adjustable welding parameters include:
Pre-arc Time Setting (PCTIME): Enhance weldability for some materials that are more difficult to weld
Gas Protection Time Setting (GPTIME): Controls the pre-charging gas time
Welding Time Setting (MCTIME): Controls the welding time to an accuracy of 1 millisecond.
Set Nail Gun Working Time (RLTIME) (Limited to Automatic Models)
Equipped with various test modes, suitable for testing the various functions of welding machines and torches.
PRE Mode: Used for testing the pre-arc function of the welding machine
LIFT mode: Used for testing the lifting function of the welding gun
GAS Mode: Used for testing the gas protection function of welding torches and machines.
Integrated welding menu, allowing direct selection of appropriate welding parameters based on the specification of the welded bolts.
Performance Features:
Effectively combat the "arc deviation" (magnetic deviation) phenomenon, significantly reduce the occurrence of deviation during gas shielded long-cycle welding, and solve industry difficulties! This means that gas shielded welding can now be used in place of ceramic ring protection welding in certain industries with high requirements.
After testing, this welder offers approximately a 10% increase in welding energy compared to the ARC800 (a bolt welding machine of the same specification produced by HBS Company). The measured welding current is about 850A, providing reliable welding capabilities for ?10 and ?12 rivets.
Our gas conduction technology provides superior air shielding and more uniform gas density during gas shielded welding, resulting in a more even weld bead shape.
