FAQ
Q1: What is the maximum material thickness this spot welder can handle?
A: Depending on the model, the DN Series can weld stainless steel from 0.5mm to 2.5 mm thick. For thicker materials, we recommend the DN-25 model.
Q2: Can this welder be used for materials other than stainless steel?
A: Yes, the DN Series is suitable for mild steel, carbon steel, galvanized steel, and nickel-plated steel.
Q3: What is the production speed of this machine?
A: The DN Series can achieve 15–25 welds per 10 seconds, depending on the material thickness and operator efficiency.
Q4: Do you provide installation and training?
A: Yes. We dispatch professional engineers to your factory for on-site installation, commissioning, and operator training. Remote technical support is also available.
Q5: What is your warranty policy?
A: We offer a standard 12-month warranty on the machine, excluding consumable parts such as electrodes. Extended warranty options are available upon request.
