KUAIQU DC power supplies automatically switch between CV and CC modes based on the load and your settings. To set a current limit (CC), short the output terminals (on supported models) or connect your load, then adjust the current knob to your desired maximum limit. The CC indicator will light up if the load draws more current than the limit set.
For digital soldering stations like the 203D, you can often enter a calibration mode by pressing specific key combinations (e.g., holding the temperature adjustment buttons). Measure the actual tip temperature with an external thermometer and adjust the display value to match.
To extend the life of your soldering tips, keep them tinned with solder when not in use. Clean the tip with a damp sponge or brass wool before and after use. Avoid using the iron at the maximum temperature for extended periods to prevent rapid oxidation.
