More of the heat developed by the arc ends up in the weld pool with consumable electrodes than with nonconsumable electrodes, with the result that higher thermal efficiencies and narrower heat-affected zones are obtained. Typical thermal efficiencies for metal-arc welding are in the 75 to 80 percent range; for welding with nonconsumable electrodes, efficiencies are 50 to 60 percent. Since there must be an ionized path to conduct electricity across a gap, the mere switching on of the welding current with a cold electrode poised over the work will not start the arc. The arc must first be ignited. This is accomplished either by supplying an initial voltage high enough to cause a discharge or by touching the electrode to the work and then withdrawing it as the contact area becomes heated. Highfrequency spark discharges are frequently used for igniting gas-shielded arcs, but the most common method of striking an arc is the touch-and-withdraw method. Arc welding may be done with either alternating or direct current and with the electrode either positive or negative. The choice of current and polarity depends on the process, the type of electrode, the arc atmosphere, and the metal being welded. Whatever the current, it must be controlled to satisfy the variables amperage and voltage which are specified by the welding procedures.

The objective in commercial welding is to get the job done as fast as possible so as to lessen the time costs of skilled workers. One way to speed the welding process is to raise the current use a higher amperage since the faster electrical energy can be induced in the weld joint, the faster will be the welding rate. With manual stick-electrode welding, however, there is a practical limit to the current. The covered electrodes are from 9 to 18 in long, and if the current is raised too high, electrical resistance heating within the unused length of electrode will become so great that the covering overheats and breaks down the covering ingredients react with each other or oxidize and do not function properly at the arc. Also, the hot core wire increases the melt-off rate and the arc characteristics change. The mechanics of stick-electrode welding are such that electric contact with the electrode cannot be made immediately above the arc a technique that would circumvent much of the resistance heating. Not until semiautomatic guns and automatic welding heads (which are fed by continuous electrode wires) were developed was there a way of solving the resistance-heating problem and thus making feasible the use of high currents to speed the welding process. In such guns and heads, electric contact with the electrode is made close to the arc. The length between the tip of the electrode and the point of electric contact is then inadequate for enough resistance heating to take place to overheat the electrode in advance of the arc, even with currents two or three times those usable with stick-electrode welding. This solving of the point-of-contact problem and circumventing of the effects of resistance heating in the electrode constituted a breakthrough that substantially lowered welding costs and increased the use of arc welding in industrial metals joining. In fact, through the ingenuity of welding equipment manufacturers, the resistance-heating effect has been put to work constructively in a technique known as long-stickout welding. Here, the length of electrode between the point of electric contact in the welding gun or head and the arc is adjusted so that resistance heating almost but not quite overheats the protruding electrode. Thus when a point on the electrode reaches the arc, the metal at that point is about
