|
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
