Dear experts,
According to the standard, the periodic test resistance of the electric soldering iron requires less than 10Ω. If I measured 60Ω, is there any risk to the product? Is the resistance < 10Ω calculated by the formula?
It is difficult to quantify the risk. Try to clean or replace the tip and see if that can bring the soldering iron back into spec.
To assess the risk, the sensitivty of the device would need to be know. Then measurments would need to be done to see if there was a voltage or current spike while the soldering iron was in operation. In the past, there were spikes when the soldring iron heater turned on and off.
If your soldering iron is reading 60Ω instead of under 10Ω, it might not be grounding properly, which could pose a risk to your work or product, especially with sensitive electronics.
Hello Mr. Yang
First of all, I also had these technical problems
but there are variables that did not allow the correct measurement.
*One of the 2 main variables are:
- What equipment are you using for this verification?
- Do you perform the measurement cold or with the tip hot?
*After that, I took into account the soldering iron with 4 more variables
- The connection cable to A/C
- The head or transformer
- The cable that feeds current to the tip
- The tip of the soldering iron
