Attach earth clamp to the workpiece, close to the weld seam and on bare metal for good conduction. Place stick electrode into the electrode holder. With the handwheel select the desired welding current. If there is not power outlet near the work area an extension cable is required. The cable's lead cross section must be at least 2.5 mm2. Uncoil extension cable fully to prevent heatbuild-up by inductance. Inductance also conside-rably reduces the welding current.

3.1.2 Function of the Stick Electrode Coating Stabilization of the arc and lonization of the arc space Protection of the weld metal from atmospheric oxygen and nitrogen bare electrode coated electrode unstable arc stable arc bare electrode coated electrode shielding gas slag This protection is achieved by the generation of shielding gases and slag during the melting of the electrode. Compensation of alloy burn-off. Stick Electrodes According to DIN 1913 Coating thickness D D d light D = 1.

Stick electrodes can be classified according to their coating as under: Type Code Type Coating Characteristics Type of Slag Slag Removal Ability Penetration Depth Gap Bridging Ability Electrode Manipulation Characteristics Weld Appearance O Bare Electrode finely distributed arc stabilizers in the electrode material minimal slag shallow excellent more difficult to weld than any other stick electrode very high deposition rate, minimal heat stress, little heat distortion convex, coarsely rippled OO

3.1.5 Arc Starting and Arc Burning Arc Strike Always start the arc in the welding groove. When the arc is stable weld over the arc strike and melt for good fusion, otherwise there is a risk of cracking. Arc starting sequence d a wrong arc strike correct arc strike open-circuit voltage Short-circuit voltage working voltage 3 to 5 V 20 to 30 V Arc Length The arc length "a", that is the distance between the stick electrode and the work, should be: with stick electrodes of coating type R, RR, A, C = 1.

4 Welding Hints Because of the multitude of and great differences in the important points for welding only the very basic operations for the most common electrodes for low-carbon steels, the Ti-type electrode, are introduced here. In the case that other electrodes have to be used, the electrode manufacturers supply upon request all relevant information for the type of special electrode to be used. Always make some trial welds on scrap material. Select electrode diameter and welding current as per Table 1.

4.1 Weld Types For Butt Welds the work piece edges should be bevelled to approx. 30°, which gives a groove angle of 60° (Pic. 10). The root opening between the two work pieces should be 2 - 3 mm. 60° (Pic. 10) For Fillet Welds "a" is the throat width size. The throat width should be at least x 0.7 the plate thickness of the thinner plate. a (Pic. 11) Other weld types: x-weld J-weld y-weld Flange weld A joint weld must always have a good fusion at the root. wrong correct (Pic. 12) (Pic.
