Welding can only use 2.5 of the electrode, the current transferred to 80A, slowly welding, yes, I have also welded. If the line is conditional, do better with sub fluorine welding or oxygen welding.
Welding is commonly known as welding rod arc. A welding operation that uses electrodes to weld metal parts at high temperatures by arcing.
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
