Operating instructions
1.Prepared before starting the machine
（1）Check whether the lubricant between the moving parts is enough or not
（2）Check whether the voltage and air pressure is normal or not
（3）Check whether there are other things between moving parts or not
（4）Check whether chip material cleaning thoroughly or not
2.Operating steps of starting
（1）To connect air suppliers，and open the regulating valve, set the pressure to 0.4 Mpa。
（2）To connect power suppliers,and open the switch on soldering gun board.and set the
temperature 340℃~350℃，（according to the thickness of solder wire to set the
temperature,before shipping,we have set the temperature already）
（3）Turn the Auto/Manual button which on the operate board to Auto status。
（4）Open operate board,first press“Resets”button,and then press“start”button to start the
machine.
（5）Check whether enough inner rubber into the feeding pathway and vibrating tray
（6）According to the color of wire to put the wire into bottom grippers correctly,and control
the machine working by foot pedal.
3.Operating steps of stopping：
（1）Power off.If long time no use, pls disconnect the power triangle plug connection with
external power。
（2）Shut down air suppliers
Note：The operator must follow the sequence of operating steps, make sure the soldering
tip in the initial position, to avoid risk.
Fault analysis and solutions：
1、Q:How to adjust when the number of rubber core in the feeding pathway is too
little？
A:Due to the power of vibrating tray is set by the electric relay auto control, when the
inner rubber in vibrating tray is too few, to lead the pathway feeding no inner rubbers
and can not meet the soldering demands,the solutions as follow:
1Add enough inner rubber into vibrating tray
2Open the switch on the vibrating tray control screen,and press“Auto UI”.Refer to the
follow steps to solve.（as the follow picture,in the normal situation,this switch status is “OFF”）

2、Q:How to adjust when the press wire easy to drop on the stripping workstation?
A:Refer to follow pictures and steps to solve:
1Regarding to the size of wire ,adjust the clamp board nuts to the properly distance between clamp
board and plastic parts.（as follow pictures,put the wire into plastic parts and press.no need to harm
the wire skin）
2First adjust clamp board nuts,to make sure the clamp board press the wire properly,and then tighten
the clamp piece nuts.
Second
steps:Change the
status to “ON”
First step:press“Monitor
UI”

3、Q:How to adjust when the knife can’t cut the wire on the cutting workstation?
A:The solution as follow:
1Check the top and bottom knives of cutting parts are broken,if yes,pls change.when fixing the
new knife,make sure the position as the same.
2Refer to the follow picture,check whether a good coincidence between up and down knife of the
cutting face,if no,it needs to add sheet piece to reach the coincidence.
