Electric Water Heater Inner Tank Production Line

GetWeld are devoting ourselves in designing and supplying water heater production line and Auto. Welding system. With professional team, we focus on full innovation solutions based on continuously enhanced technology, not just supply separate and conventional machines, but concentrating on follow-up project automation upgrading, we offer continuous and prospective project proposal. Keeping on site production supervision and phased acceptance can make sure of perfect product quality and reliable machine performance. Before machines are dispatched, equipment system integration and successful trial running on line is our advantage. And professional commissioning and training is one of work.
