ESAB OK21.03 Gouging Electrodes
ESAB OK 21.03 gouging & cutting electrodes size 3,2mm x 350mm long packed in 3.5 kg box also avaible as a “slab” of 3 packs = 10.5kg.
These electrodes have been designed for use at 15-20 degrees and pushed forward in the direction of travel. The gouging speed is generally between 1000 and 1500mm / minute.
Multiple passes may be made to make deep gouges. Welding may take place immediately afterwards in mild steel.
If gouging stainless steel the gouge path must be ground clean to remove the carbon deposit the gouge rod leaves.
Gouging makes a lot of fume and this will need to be taken into account.
The 4,0mm gouging rods should be operated at 130 to 180 Amps.
