ⅩⅢ型焊枪以设计轻巧、外观大方和配件简单著称。但该焊枪的输电缆、送丝软管、送气管和控制电缆是压制在一起的,看似简单而制做复杂。使用中任何一条管线路出了故障都无法修复,整条焊把线就得报废。而且焊把导线僵硬,挺度大,使用时焊枪变换角度的灵活性较差,尤其对直径较小的环焊缝焊接时,更不方便。往往因焊枪角度调节困难造成焊偏。该焊枪在大规范(450A),高载率(90％左右)使用时,输电缆过热焊把烫手。把线与送丝机连接处烧
Ⅹ Ⅲ-type welding torch to design lightweight, generous appearance and accessories known for simplicity. However, the welding torch transmission cable, wire feeding hose, air supply pipe and control cables are suppressed together, seemingly simple and complicated to make. The use of any one line out of the fault can not be repaired, the entire welding line have to scrapped. Moreover, the wire of the welding rod is stiff and stiff, and the flexibility of the torch changing angle is poor when it is used, especially when the welding of the small diameter girth welding is even more inconvenient. Welding torch angle is often caused by the difficulty of welding angle. The torch in large-scale (450A), high load (about 90%), the cable overheating welding hot. Wire and wire feeder connection Department burn
