How does the flux recovery system work?

The system collects unmelted granular flux using a suction device, filters and purifies it, and returns it to the hopper for reuse, reducing waste and improving efficiency.

What payment methods are accepted?

We accept LC, T/T, D/P, PayPal, Western Union, Small-amount payment, and Money Gram.

Can the machine be customized for specific requirements?

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company involved in selling welding machines, materials, and related industrial components, although other slices describe it as a professional technical supplier and OEM provider. It holds ISO 9001 certification and reports overseas service offerings including installation, debugging, maintenance, repair, and training, supported through overseas agents or branches. Production information states an annual output of 500 automatic welding machines, with peak-season lead time of one month and off-season lead time within 15 workdays. The supplier offers flexible customization, 3D software design, ODM, and OEM services, but reported no new products in the past year and no SDK availability. Evidence of financial credibility, named customer cases, raw-material traceability, and documented supplier-service assessment procedures is insufficient. The supplier has participated in FABEX Metal & Steel and reports exports representing 41%–50% of total sales.

CertificationsThe supplier reports certification under ISO 9001 supplier management systems. This is explicit evidence of holding a recognized quality-management certification.

After-Sales capabilityThe supplier reports overseas installation, debugging, maintenance, repair, and training services in Russia, and states that it can provide services through overseas agents or branches. It has also participated in FABEX Metal & Steel, but its service-capability assessment lacks written procedures and records, while corrective and preventive action procedures have no written records.

Production capacityThe supplier reports annual production of 500 automatic welding machines, 11–20 quality-control staff, and peak- and off-season lead times of one month and within 15 workdays respectively. These figures provide explicit evidence of production and quality-control resources, although no direct benchmark is supplied to show that capacity exceeds requirements.

Customization capabilityThe supplier explicitly provides flexible customization, 3D software design services, ODM services, and OEM services for popular brands. These capabilities directly support customized product and design requirements.
