Recently, a customer inquired about our WP630A butt welding machine, where the heating plate temperature stops rising after reaching 180°C. What could be the reason?

In such a situation, the first step is to check if the circuit connection is proper. The following video demonstrates the use of a clamp ammeter for this purpose.

Note: If you are unfamiliar with circuits and current measurement, please consult us. Our company has professional electricians and technical personnel who can provide guidance.
