Semi-automatic copper rod butt welding machine belongs toResistance welding machineMajor categories of butt welding machines, some people also call them copper wire butt welding machines, mobile CNC butt welding machines, cable butt welding machines,
The model of Xinxing Welding is: UN2S. ItsCommon faults and troubleshooting methods are as follows:
firstUN2SAfter long-term use of the semi-automatic butt welding machine, the moving parts will wear out to some extent. You can purchase the following parts from the manufacturer.
Copper rod butt welding machine head assembly It includes:Carriage plate (pig iron casting), brass static machine head, brass movable machine head, screw, copper electrode,
Brass upper electrode pressure block (including pressure plate)
Fault phenomenon
Possible reasons
Troubleshooting
The power indicator light does not light up, press the button,no response
1 The incoming power supply 380v is not connected
2The power switch is not closed.
1、Check input power
2、Close the power switch
The power light is on, but after pressing the buttonThe controller does not light up when it is started.。
1、broken button
2、Wire loose
1、Change button
2、Cut off the power supply and check the tightening wire connection screws
The welding light is onBut the weldment is not welded
1、The weldment is severely rusted or oily or the end face is severely oxidized
2、The surface of the copper electrode is severely oxidized
3、The upsetting force is adjusted too small
1、Clean weldments
2、Clean copper electrodes
3、Machine right hand side clockwiseIncrease upsetting force
2 The temperature of the weldment is uneven, one side is red and the other side is not.
1、The left and right extension lengths of the weldment are inconsistent
2、There is oneThe copper electrode on the surface is worn, and the contact between the weldment and the electrode is poor.
1、Reinstall the clamp so that the left and right weldments protrude from the electrode by the same length.
2、Correct or replace copper electrode
When welding copper materials, an explosion sound occurs at the end of the welding
1、The movement of the active electrode is blocked and inflexible
2、The upsetting force is adjusted too small
3、Welding time is too long
1、Lubricate moving parts
2、Fix moving parts
