Hardware knowledge: resistance welding and cutting skills

Hardware knowledge, resistance welding and cutting skills:

1. Resistance welding is not suitable for welding aluminum, copper or copper alloys. It is only used for welding steel and stainless steel.

2. To get more heat (current output), a shorter electrode arm should be used.

3. If it is a welding machine without heat control function, the length of the electrode arm should be used for control. For example, long electrode arms are used when welding thin plates that require low heat.

4. Note that the longer electrode arm may bend and you may lose the pressure on the weld. Import pump valve

5. Make sure that there is no gap between the welding workpieces, otherwise the welding effect will be greatly affected.

6. Keep the two electrode arms aligned so that the electrodes are aligned with each other. Also, keep the pressure adjusted properly, not too big or too small.

7. If you need a certain side of the workpiece to have a good appearance after welding, you can smooth (using a machine) the electrode side.

8. Clean the electrode frequently, otherwise the output (current) will decrease. You should also wear a suitable protective cover to the electrode.
