Please use 4s battery fully charged
Theoretically, up to 30v can be used.
However, the higher the voltage, the more sparks are generated and the more difficult it is to control the exact strength.
Use wires that are thicker than 8awg.
The thickness of the wire limits the current.
Battery performance differs from maker to maker.
The battery manufacturer uses wires that match the battery output.
What is the AWG of the battery?
My recommended battery is 10AWG.
If the battery wire is 12awg...
Is the left side of the picture (minus the battery) properly spot welded?
The right side of the picture (plus on the battery) appears to be in the wrong position.
Make sure that both electrodes are located on the battery terminals (metal part).
What kind of battery did you use?
Battery...
Please connect the soldering iron tip to the handle and turn on the power.
So the tip temperature is displayed correctly.
The soldering tip may occasionally have a different resistance value.
