INTRODUCTION
The Programmable Pass Through machine automates the end preparation of pipes for fabrication
using a program that makes saddle cuts, offset (hillside) cuts, lateral cuts and mitre cuts. The SE-4PTD
rotates a pipe held in its three-jaw chuck while driving a cutting torch back and forth along the pipe axis,
so that the torch cuts a contour on one pipe to fit onto another pipe of larger diameter. Pipes from 4”
(100 mm) to 12.5” (318 mm) outside diameter can be chucked internally in the machine. Smaller pipes
require optional extension jaws. The SE-4PTD is suitable for plasma and oxy-fuel cutting and elimi-
nates the need to make templates or layout complex cuts.
DESCRIPTION
The SE-4PTD is designed to sit on a work table. The machine can be used with oxy-fuel torched or
plasma. If the machine is set up for oxy-fuel cutting, the 3-hose cutting torch is connected to the solenoid
manifold located on the left hand side of the machine. If the machine is set up for a plasma torch, it will
be equipped with a rotary ground and holding clams for a plasma torch. The suggested method of
plasma cutting will be air plasma. Power requirements are 240 VAC single phase and a clean air
supply for the plasma source. The SE-4PTD should be operated from a separate power line; it can be
supplied for voltage ratings of 120, or 240 VAC.
Panel controls include Start, Stop, and Reset push buttons, a joystick for manual positioning, and speed
control knob which are shown on page 4, Panel Controls. All programming is done using a hand held
terminal, with keypad and display. (See page 9).
SET-UP
Place the SE-4PTD on a work table, preferable bolting it down through the mounting holes located in the
legs of the machine. Plug the power cord into the power line. The torch arm should be already inserted
into the linear drive located on top of the SE-4PTD. If it is not, throw the power switch on, and carefully
insert the slide into the V-wheels inside the linear drive from the chuck end. Then, using the manual
joystick control, drive the arm back in to the machine. Push the reset button so the machine holds its
position.
Insert the cutting torch into the torch holder by loosening the clamping lever and adjusting its position so
that the torch is centered in line with the chuck axis. Then, lock the torch holder in place.
For plasma, mount the relay contact box on the short post located on the top right hand side of the
machine above the control panel. Plug the relay into the contact output. Wire the trigger leads for the
plasma machine to the supplied connector and plug into the relay box.
Loop the gas hose or plasma cable over the cable hanger located on the top right hand side of the
machine above the control panel, for support. Plug the programming pendant cable into the 6-pin
connector located on the control panel.
