tion The danger is particularly great in hot weather when he is sweaty He should develop the habit of keeping his body insulated from both the work and the metal electrode and holder He should never permit the bare metal part of an elec trode, the electrode insulation, or any metal part of the electrode holder to touch either his bare skin or any wet covering on his body Consistent use of well insulated electrode holders and cables, dry clothing on the hands and body, and insulation from ground will be helpful in preventing contact Some specific precautions for prevention of electnc shock are 1 In confined places, cover or arrange cables to prevent contact with falling sparks 2 Never change electrodes with bare hands or wet gloves, or when standing on wet floors or grounded surfaces 3 Ground the frames of welding units, port able or stationary, m accordance with the National Electrical Code With a small welding unit, a primary cable containing an extra conductor, one end of which is attached to the frame of the welding unit, can be used By means of the proper po larized plug, this ground connection can be earned back to the permanently grounded connection in the receptacle of the power supply 4 Arrange receptacles of power cables for portable welding units so that it is impos sible to remove the plug without opening the power supply switch, or use plugs and receptacles which have been approved to break full load circuits of the unit 5 If a cable (either work lead or electrode lead) becomes wom, exposing bare con ductors, cover the exposed portion with rubber, plastic, or friction tape equivalent to the cable covenng 6 Keep welding cables dry and free of grease and oil to prevent premature breakdown of the insulation 7 Suspend cables on substantial overhead supports if the cables must be run some distance from the welding unit Protect cables that must be laid on the floor or ground so that they will not interfere with safe passage or become damaged or en tangled 8 Take special care to keep welding cables away from power supply cables or hightension wires Gas-shielded arc welding Gas-shielded arc welding (Fig 31-8) is used for joining all types of metals and cast ings In gas-shielded methods, only one electrode is used A gas or gas mixture is in troduced through the torch to surround the electrode and the welding point like a shield The gas cone protects the molten weld pud dle from the atmosphere and stops oxidation of the base metal The electrode conducts either alternating or direct current to provide heat Tungsten arc In gas-shielded tungsten arc welding, the electrode does not melt and is not used for filler metal The electrode is tungsten, which is highly resistant to heat and non-consumable m the welding process Metal arc.
