arc welding

Welding process in which the heat needed for fusing is provided by an electric arc between the electrode and the part to be welded.

ground clamp

Tongs connecting the part to be welded to the work lead.

work lead

Cable returning the current to the arc welding machine.

arc welding machine

Device providing a current to the electrode; the current’s intensity depends on the nature of the parts to be welded and the electrode’s characteristics.

electrode lead

electrode holder

electrode

Detachable metal pin; it conducts the current and produces an electric arc.

welding curtain

Movable panel that stops the sparks and harmful light rays emitted while welding.
