Why can't I repair the cold welding machine Easy to fall off

Question: Why can't the patching machine be fixed? Easy to fall off?

Answer: The main reasons for the failure to fix are:

1. The surface of the mold is not cleaned, and there are impurities such as oil, dirt, and oxides between the supplement and the mold.

2. Improper power adjustment, and the thickness of the replenishment material does not match the adjustment power.

3. The connection wire is in poor contact, the contact part of the strong magnetic negative wire and the mold is dirty or there is an oxide layer, there is an oxide layer or impurities between the welding head and the repair material, the repair material and the mold, the output terminal and the electrode wire terminal.

4. The material of the repair material and the base material of the mold is not suitable for cold welding and cannot be repaired.

5. Due to long-term twisting of the connecting wire, the internal part of the wire is broken, causing insufficient welding current.

6. Only one ground wire is connected during welding, causing insufficient welding current.
