återledare, returledare Explanation: Don't mix the "work lead" with the "ground lead"! -------------------------------------------------- Note added at 9 days (2019-11-13 11:27:28 GMT) -------------------------------------------------- Dear Catrine, I understand your text is about welding equipment. Such device has two separate voltage circuits: 1) the mains supply, and 2) the welding voltage. The circuits are separated in the until, normally with a full transformer. The mains supply consists of the phase (fas), return (nolla) and ground (slyddsjord). This ground is connected the unit's covers and acts as a protection in case of an isolation fault in the unit. The work lead is the cable that connects the welding unit to the work piece. On the workplaces you will hear the guys call it "jordledning" which it is not. A more correct name would be "returledning". The other cable is the "gun cable" between the welding unit at the welding gun. The two latter cable carry the welding current through the work piece. The mains ground must NEVER be connected to the welding return line. In case of an isolation fault in the unit the welding cables would the carry the mains voltage which can result in electric chock and death. |
