特点和用途：
1.TUN3系列对焊机是为铜管与铝管连接的一种焊接设备，它可替代原先使用的高压闪光对焊机和高频钎焊。
2.系统采用了可编程序逻辑控制器（PLC）为动作逻辑控制单元，微电脑焊接控制器为焊接工艺控制单元，使用铝合金气缸，含油轴承和精密机床用光杆配合保证机械动作的性，具有可靠的焊接质量，控制与调整直观简便，生产效率高，基本无漏焊漏气现象，成品率高等优点，同时克服了原来焊接工艺需要对焊接管内二次加工和工作电压高易出事故的缺点。
3.装有初级恒压和次级恒流的控制系统、强制水冷系统、气源储气罐，确保大量生产，焊接质量和焊接效果完全一致。
4.可储存多组不同焊接规范，根据不同的管径和壁厚调用不同的规范，操作简单，效率高，广泛应用于空调、冰箱、冷柜、冷库、压缩机等产品。
Features and application:
