I have problem about the welding machine
At the check edge sensor.(photoelectric switch (groove type))
Some sensor malfunction and not working. Not have a red light
Check and correction
1.Cleaning the sensors
2.Check voltage 23.8 v
3.Try switching to another usable. Sensor is not working.
Therefore, the probability that a sensor is broken or not
Do you think how it would be resolved.
Or can you sent a new one for replacement ?
