Specification :

Electrode with special covering for welding alumunium-silicon alloys and for joining disimiliar alumunium alloys. in welding, hold electrode perpendiculary to workpiece, with a short arc. wall thichnesses greater than 10mm and larger workpieces will require preheating from 150C - 250C, since slag residuesare corrosive, they must be completely removed from the weld bead. Electrode serves well as consumable in axyacetylene welding. The covering being hygroscopic, electrodes must be strored in an absolutely dry location, or redried if required.
