中国漳州兴华焊接机厂的 QH ARC—103(103A)型焊机是应用清华大学研制并获得国家重大科技发明一等奖的“QH—ARC 电弧控制法”制造的最新型脉冲 MIG 焊机,与国外同类焊机相比,以其优越的性能居于领先地位。本焊机是在新颖的晶体管电源上加以独特的自适应电弧控制系统,使电源呈现具有动态扫描的多折线外特性,其脉冲参数能依照送丝速度自动优化,实现了单旋钮控制,焊接过程能始终保持熔滴的喷射过渡和稳定的弧长,并
QH ARC-103 (103A) welder of Xinghua Welding Machine Factory in Zhangzhou, China is the latest pulse MIG welder manufactured by “QH-ARC Arc Control Law” developed by Tsinghua University and won the first prize of National Major Scientific and Technological Invention. Compared with similar foreign welding machine, with its superior performance in a leading position. The welder is a unique adaptive arc control system on the novel transistor power supply, so that the power supply presents a multi-folding line with dynamic scanning characteristics, the pulse parameters can be automatically optimized in accordance with the wire feed speed to achieve a single-knob control, the welding process Can always maintain the droplet spray transition and stable arc length, and
