Common Faults and Troubleshooting Methods of Electrical and Hot Melt Welding Machines for PE Pipe Fi

Heating welding machine The fault phenomenon Possible reason Elimination method
No electricity Fuse burn out, power interface problem Replace the accessories and reconnect the electricity
After power on, the display screen does not show, flower screen, robot beeping Display screen damaged (dampness, heat, impact, aging, wire loss) Rewire and replace the display screen
The current can't go up Undervoltage of external power supply and excessively long power line laying Check external power connection and reinstall
Turn on the power and do not operate according to the set parameters normally The first section current parameter is set too low Increase the current parameters in the first stage, the time is less than 30S, and then carry out the welding of normal parameters continuously
Display abnormal welding PE pipe element heating short circuit Stop welding and wait for cooling before welding
Display the output circuit breaker, the resistance value exceeds the lower limit PE pipe fitting abnormal Check PE pipe fitting and replace it for welding
Abnormal welding process, hot terminal Output copper cap aging Fix the brass cap or replace it with a new accessory
Display overcurrent and overvoltage External power supply problem Check external power supply and rewire
Hot melt butting machine The motor works but the hydraulic drive is ineffective Hydraulic oil is not in the nominal position Check the hydraulic oil and select the specified mark hydraulic oil for supplement
The electric cabinet instrument does not display Parts are damaged or wiring is loose Inspect accessories and wiring for replacement or repair
The heating plate is not heated or the temperature is not controlled The line falls off or the temperature controller is damaged Check wiring and replace parts
The high-pressure pipe joint leaks oil Quick plug damage Replace quick plug
Component not working Poor contact of aviation plug and socket Check and replace parts
Motor not working The wiring is off and the motor is damaged Inspection and maintenance
