Cold welding occurs when the weld is not heated properly and does not adhere properly to the metal parts. Here are some possible causes and solutions for this problem:
- Insufficient current: If the electrical current is too low, the weld will not get hot enough. Be sure to check the current setting and increase it if necessary.
- Short welding time: If the welding time is too short, the weld will not have enough time to heat up properly. Adjust the welding time as needed.
- Insufficient welding force: If the applied welding force is too low, the weld will not adhere properly to the metal parts. Increases the welding force on the machine.
- Overlap too large: Too large an overlap can cause a cold weld. Make sure the overlap is within the recommended specifications for your machine and material.
- Thread condition: Check the thread width and surface condition. If the wire is damaged or dirty, it can affect the quality of the weld. Clean or replace the thread as necessary.
- Condition of the welding sheaves: Make sure that the welding sheaves are in good condition and properly adjusted. If worn or damaged, they may need to be replaced or adjusted.
- Cleaning and maintenance: Make sure the machine is clean and well maintained. Accumulation of dirt or debris can affect the quality of the weld.
I suggest that you check these aspects on your Soudronic welder and make the necessary adjustments. If the problem persists, you may need to contact Soudronic technical support for further assistance.
