4.10 GOUGING (continued)
The tip to work distance affects gouge quality and depth. A
standoff of 1/8 - 1/4 in (3 - 6 mm) allows smooth, consistent
metal removal. A smaller standoff may result in a severance cut
rather than a gouge. A standoff greater than 1/4 in (6 mm) may
result in minimal metal removal or loss of transferred main arc.
Slag generated by gouging on materials such as carbon and
stainlesss steels, nickels, and alloyed steels, can be removed easily
in most cases. Slag does not obstruct the gouging process if it
accumulates to the side of the gouge path. However, slag build-
up can cause inconsistencies and irregular metal removal if large
amounts of material build up in front of the arc. The build-up is
most often a result of improper travel speed, lead angle, or
standoff height.
