Electrode manipulation -- #welding

to the thickness of the plate diameter and type of electrode dictate the proper current setting in this case a 532 AWS class e610 electrode with DC reverse polarity calls for a machine setting of 13 amp which should produce 24 to 26 volts if the arc length is correct upon starting the arc the operator must build a foundation or shelf of well metal to support the molten pool as it is deposited control of molten metal in vertical welding is largely a matter of electrode manipulation the metal melts off the electrode crosses the arc mixes with the molten base metal gravity causes this molten metal to flow down to the rear of the pool to prevent this fluid metal from flowing over the face of the weld it is necessary to remove the heat momentarily to allow the molten metal to
