Do power supplies need ground?
In most power supplies the + and the – would be floating (isolated). A third Gnd connection is really not necessary. Some power supplies may have an additional output connected to protective earth and then you can use this if you need it. If the PS has a metal case then it would normally be grounded to PE.
Why is it important to have an understanding about soldering iron?
Soldering makes effective and reliable electrical connections. Soldering starts by cleaning the components to be joined. The next step is to mechanically connect the two components by wrapping the cable around the component. You will need a soldering iron to melt the solder and joint the components.
Can a soldering iron be set to ground?
A grounded soldering iron will have its body set to ground. Generally if a soldering iron power plug has a third prong (the ground prong) then the soldering iron will be grounded.
Can a DC charger be used with a soldering iron?
CP9348S is a multifunctional instrument that integrates digital display temperature soldering iron, USB charging and adjustable DC power supply. It uses advanced MCU, combined with high-quality code potentiometer to achieve high stability DC Voltage and DC Current output. 5V/2A USB interface could be used for charging phones.
Which is DC power supply variable with soldering iron station?

Why do power plugs have to be grounded?
Generally if a soldering iron power plug has a third prong (the ground prong) then the soldering iron will be grounded. This helps prevent shocks because any current leakage will be directed towards ground and not towards you.
