We allow 15 days for the customer to contact us about a defective machine. Within that 15-day period, you can either take the defective machine to a certified repair facility and have the machine repaired OR return the machine to us for an exchange. We never ship a replacement machine until we receive, inspect, and verify the original machine is defective. Outside of the 15-day window, the customer must have the machine repaired per the manufacturer’s warranty guidelines. The customer is responsible for any return shipping to Flint Welding Supply Co. or getting the machine to a repair facility.
