Who we serve
We work with distributors, hardware store chains, online retailers and light fabrication buyers, primarily in North America, Europe, Latin America and Russia, as well as other international markets.
COROTC provides OEM and ODM customization for welding machines and plasma cutting equipment. OEM covers brand implementation: machine LOGO, housing colour, panel sticker, packaging box, instruction manual and country-specific plug. ODM covers product definition: appearance, functions, display screen, output current and input voltage, with product construction addressed across four dimensions — OPERATION, FUNCTION, OPTIMIZATION and COST-REDUCTION. Each track comes with an itemized list that can be checked item by item, so the scope of change can be set against the target market and product positioning. Available customization items are confirmed per model, since current ranges and voltage options are defined for each machine type. Minimum order quantity is likewise confirmed per model. Sampling and delivery lead time: approximately 14 days.
