No matter it is DTNStainless steel spot welding machineIt is also an intermediate frequency spot welder. High heat will accumulate inside during welding. The rising temperature will easily soften and wear the copper of the welding head and transformer. In severe cases, it will be transmitted to electrical appliances, thereby shortening the service life. Professional research data shows that when a welding machine is operated in a high temperature environment above 50 degrees for a long time, its service life is reduced by two-thirds, which requires the use of a heat dissipation system.
