WELDING TOOLS AND ACCESSOIRES

Electrode Holders.

An electrode holder is a device for clamping an electrode and conducting an electric current to it. An electrode holder should meet the following requirements.

(1)  To hold the electrode in a position convenient for welding.

(2)  To establish a reliable current connection to the electrode.

(3)  To allow an easy and quick change of electrodes without the operator having to touch any current-conducting or hot parts.

(4)  To have a handle which will not grow hot during the welding operation.

(5)  To weigh not more than 600 grams for a maximum current of 300 amp.

The operator should handle his electrode holder with care and keep watch on its condition.

Welding Cables.

The welding current is conducted from a generator or transformer to the work by welding cables. A welding cable should not be longer than 20 to 30 metres, because a longer cable may appreciably reduce the welding voltage.

The size of welding cables varies, being dependent on the welding current employed, but it should be sufficient for a temperature rise of 80°G,
