Frequently Asked Questions (FAQ) about welding current controller used in round chain production.

 

Q: What is a welding current controller?

A: The welding current controller is the core component of the chain welding machine's control system. It is responsible for precisely adjusting and stabilizing the welding current to ensure consistent weld quality for each chain link. It is typically installed inside the welding machine's control cabinet.

 

Q: How many types of welding controllers does Hangzhou Polywin Machinery offer? What can they control?

A: Currently, there are two types: the mains frequency resistance welding controller and the medium-frequency inverter AC resistance welding controller. Both allow for easy adjustment of welding parameters based on different welding conditions. The most important parameters are: preheat time, preheat current, welding time, welding current, tempering time, and tempering current.

 

Q: What is the difference between the mains frequency resistance welding controller and the medium-frequency inverter AC resistance welding controller?

A: 

***The figure on the Left:Mains Frequency,at 50Hz input power frequency and a 10kA secondary current with an 80:1 turns ratio on the transformer;

***The figure on the Right:Medium-Frequency AC Controller, same ourput current (50Hz input power frequency and a 10kA secondary current with an 80:1 turns ratio on the transformer)

1.Mains Frequency: Its biggest advantage is low cost. The technology is very mature, making it an economical choice for producing ordinary carbon steel chains where strict process standards are not required.

2. Medium-Frequency AC Controller:

Compared to ordinary mains frequency controllers, the medium-frequency AC controller offers the following advantages:

1) Three-phase AC power input, balanced power consumption, high power factor.

2)Shorter welding time for the same workpiece, saving electricity; wider stable welding zone; longer electrode life.

3)Capable of welding various materials including stainless steel, carbon steel, high-tensile steel and titanium, with excellent results.

4)Suitable for precision welding requirements.

5)Less spatter during welding.

6)Fast current response control improves weld quality.

 

Q: How to choose a welding current controller for different welding machines?

A:For 3-6mm chain welding machines CE01W-75: Choose mains frequency controller.

For 5-10mm chain welding machines CE02W-125 (capable of welding 11mm chains):

Choose mains frequency for long-term mass production of small-size carbon steel chains.

Select medium-frequency inverter AC controllers if processing stainless steel, continuous welding of 11 mm chains, or manufacturing Grade G100 chains.

All models designed for chains over 11 mm adopt medium-frequency AC inverter controllers.
