Brushing Pressure
1.Remember, the tips of a wire brush do
the work. Operate the brush with the
lightest pressure so only the tips of the
wire come in contact with the work.
2.If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of
the brush will be shortened due to wire
fatigue.
3.Apply the brush to the work in such a way
that as much of the brush face as possible
is in full contact with the work. Applying
the side or edge of the brush to the work
will result in wire breakage and shortened
brush life.
