Recently, our company received inquiries about chillers from customers in Guangxi. The customers are mainly engaged in R&D, production and sales of resistance welding machines. Their products are widely used in electronic product welding, lamp welding, and hot pressure welding. Since the resistance head is prone to high temperature during the working process of the resistance welding machine, which affects the accuracy of the processed product, a chiller is needed to cool it next to ensure the accuracy of the processed product.
