WF—007A
handheld laser welding machine with wire filling system wire feeding machine
Introduction：
WF-007A Cold filler wire machine (argon arc welding wire feeding machine) is used for argon arc welding, laser welding, plasma welding, brazing welding process, withoutpreheating wire filling equipment for the molten pool. 
WF-007A has a total of three kinds of working state, respectively is: the standbystate, parameter setting, running state. Turn on the power switch, which enter the standby state.
