About Us

About Hotar Welding Co., Ltd.

Founded in 2012, Hotar Welding Co., Ltd. is a specialized manufacturer and supplier of robot welding torch consumables and spare parts for automated MIG/MAG welding production.

We focus on developing full‑range compatible components for OTC‑Daihen robotic welding torches, delivering one‑stop consumable solutions for welding distributors, robot integrators, maintenance workshops and high‑volume manufacturing facilities worldwide.

Our product portfolio covers core robot welding spare parts including contact tips, nozzles, gas diffusers, tip holders, insulators, goosenecks, torch bodies, wire feed liners, sealing gaskets as well as complete robotic welding torches. We also offer application‑oriented consumable kits — from quick‑change service packs and annual bulk supply kits to dedicated kits for aluminum welding and torch‑head rebuild.

We strictly control raw material and precision machining quality. By offering both E‑Cu red copper and high‑performance CuCrZr material options, we help our customers balance production cost, service life and stable current transfer for continuous robotic welding cells.

We understand the pain points of automated welding operations: unexpected downtime caused by mismatched or poor‑quality consumables. That is why we provide professional compatibility verification service. Send us your torch model, part photos or drawings, and our engineering team will confirm the correct matching solution before quotation.

All our compatible replacement parts are engineered for seamless fit with OTC robotic torch systems. Product reference numbers are for cross‑reference identification only and do not represent original OEM products.

Committed to “KEEP EVERY WELDING CELL MOVING”, Hotar Welding strives to be your reliable long‑term partner for robotic welding consumables. Whether you need sample testing, small‑batch orders or large‑volume annual supply, we support flexible sourcing to match your project requirements.
