No. There are no hidden fees — send your request with clear evidence, and we will resolve the issue as quickly as possible.

You receive free replacement parts — shipped to you free of charge — plus free remote technical support from our engineers to guide the repair.

Support continues for the product's lifetime: cost-only replacement parts (no markup) and free lifetime remote technical guidance.

Email us clear photos and/or videos of the issue first — visual evidence is the most important step. We verify the damage is non-man-made (manufacturing or material defects under normal use; misuse, incorrect voltage, impact, water ingress or unauthorized modification are excluded), then proceed with the warranty service.

Every COROTC welder is covered for 1 year from the shipping date — your warranty clock starts when your order leaves our warehouse, not from the manufacturing date.

Selected models are stocked in our U.S. and Russia warehouses for faster local delivery and easier after-sales support. Other orders ship from Shenzhen, China. Contact us for the current stock list.

We serve North America, Europe, Latin America and Russia, and regularly support orders to other markets. Send us your destination port or address and we will confirm the best shipping option and cost.

Lithium batteries are regulated goods in international freight. Selected battery models ship with UN38.3 test reports and MSDS, which are required for smooth customs clearance and transport.

MOQ and lead time vary by model and order quantity. Contact us with your target models and quantities, and we will reply with current MOQ, lead time and a detailed quotation. 

We supply welding equipment to distributors and importers across North America, Europe, Latin America and Russia — including cordless, MIG, TIG and stick welders, plasma cutters and weld cleaning machines.
