1. Are each segment's current and time adjustable?

Your question is about achieve even and constant fusing quality for each segment,

The DC power supply machine with high requency's output current is even and constant, can make sure even welding quality,

On machine parameter set screen, there is 6sections welding current and time setting for armature with many hooks such as 63hooks,

and for a 24 hook commutator, you can divide the welding parameter to 3 stages by setting Bar. no. as 1+22+1 = 24 or divide the setting to set 1+1+1+2+3+16 =24

considering heat up time for electro rod and actual situation,

In actual production, some user just set the Bar No. in Section1 as 24,

2. How electrode distance is controlled?

The distance suggested is about 1.5mm to 2mm, should be more than 1mm in case the commutator OD have some difference,

You can check by a 1.5mm thickness commidity as a

3. How the pressure applied by the electrode to the hook is adjusted and controlled?

With diffent size of Press Spring the pressure can be adjusted, for rough control with spring,

for slight control with screw on top

4.Is there any load cell to control this pressure?

Yes,

Our hydraulic and servo press machine for commutator, shaft placement have this kind of load cell which can control and show pressure,

We are applying this to the new fusing machine with servo device pressure later,

This will be applied for local motor manufacturer who required first

5. What are the steps of the fusing cycle, how each portion of this cycle is adjusted?

Fusing cycle is electrode touch the commutator hook, then press the commutator hook, holding the pressure and release

Please check graphic of the fusing cycle on welding setting photo

This cycle is related to four factors,

the electrode and commutator hook contacting face area,

pressure value, holding the pressure time, fusing voltage

You can get a best cycle by teamwork of this four factors,

High frequency 15KHz ensure the pure output DC current, while some fusing machine 2KHz, 4KHz not high frequency

The constant current can make sure fusing each segment without hesitate, so DC power supply is faster and save electricity

6. Is there any warning sign for bad fusing?

Yes, machine have this function
