WELDING ROD WITH A LOW HYDROGEN CONTENT AND POWDER IRON COVERING. ITS FILLER METAL IS A
LOW CHROMIUM-MOLYBDENUM ALLOY WITH HIGH MECHANICAL RESISTANCE.

4.8 Y 10 CHARACTERISTICS AND PROCEDURE: This electrode filler metal has a very nice
appearance and the resulting weld seams are flat, smooth, without cavities or splatter.
The slag can be easily removed. It can be used in all positions.
Clean the joint area to remove dirt, scales, grease and rust. Keep the arc short with the
electrode slightly tilted in the same direction as the weld. Swinging while welding should
not triple the core diameter. When using DC, connect the electrode holder to the positive
pole (reverse polarity). Remove the slag between one pass and the next. Precaution: Electrodes with a low hydrogen content covering are hygroscopic (they
tend to absorb and retain water from the surrounding air) so they should be kept in a dry,
