3.0 Operating Instructions
3.1 Description of Power Tool
PortaCo’s model WS-10-64-3 Weld
Shear is intended to be used to
shear Thermit and Buta type welds.
It's light-weight construction and
auto cycle valve reduces operator
fatigue.
The closing rate of the shear
blades, are limited to the industries
standard and cannot be altered.
When the control lever is release
the blades automatically retract at a
more rapid rate to reduce shearing
time.
The PortaCo Weld Shear secures to
the rail at four points. Adjustable
roller hold downs provide a smooth
shearing operation and guide the
shear on worn rail. Hold down
assemblies have been designed to
be easily serviced in the field.
Hydraulic quick connect couplers
are located at the rear of the tool to
allow more convenient routing of the
supply hoses.
Fully guarded hydraulic plumbing
protects the operator from
accidental leakage of oil onto the
welded area, reducing the potential
for a fire.
The G-18D55-53-W is a versatile
power unit that can meet the needs
for most hydraulic tools used by the
rail road industry. This power unit is
capable of powering two tools
simultaneously at 5 GPM (20 LPM)
or one tool a 10 GPM (40 LPM) all
the flows are at 138 BAR (2000
PSI). The maximum pressure of the
hydraulic system is limited to 148.3
BAR (2150 PSI). The power source
provided the required flow and
pressure to operated HTMA type I
15-23 LPM (4-6 GPM) and type RR
34-40 LPM (9-10.5) tools. All which,
are OPEN-CENTER tools required
an operating pressure of 138 BAR
(2000 PSI).
3.2 Controls and Graphics
The following decals are placed on
the tool to aid in its operation and
maintenance. The operator should
locate and understand them before
using this power tool.
The weld shear has five instructional
decals located on the tool.
On the hydraulic system guard cover
there is a CAUTION decal that
specifies that the weld shear is rated
for a flow of 10 GPM/40 LPM and
pressure of 2000 PSI/150 BAR do
not exceed these flow / pressure
ratings. Also on the decal is a few
written warnings “improper use may
cause severe injury, read and
understand operators manual before
operating tool, keep all guards in
place, during operation always wear
gloves, safe clothing and footwear,
and during operation always wear
approved safety protection for ears,
eyes, and head.” (figure 3.2A) (figure
