Gold bridge welding electrodes in the specifications of the original acid, carbon steel, alkaline carbon steel, stainless steel, low alloy steel, surfacing, cast iron more than 30 varieties of six categories on the basis of more than 100 kinds of products, add different types of electrode, with a very strong operability. Easy to take off the residue. Location off the residue in the T-joint fillet weld, butt angle of the weld metal and boat welding Ying, etc. net and welding, fillet welding position residue since Alice, the whole fall off the edge and the weld surface sticky residue. Splash-class small. The splash can be divided into three levels, small splash (litter spatter or usually spatter) spatter (very little spatter) and no splash (no spatter). Majority at the first level, a few manufacturers at the second level, there is no third level splash of scaffolding electrode. Then arc sexual. Require drug leather sleeve dark straight, the depth of 3 mm or more, and then arc extremely easy, under normal conditions, free from the limit of the interval. The all-position welding. Performance 4mm large-sized electrode for all position welding. Weld shape and color. Weld forming fine bright, weld color was silver-white or golden yellow. Welding rod, security and non-toxic.
