Section I - Safety Precautions for Trench Machines
1. Keep working area clean and tidy.
2. Keep electrical tools away from moisture. Never use in wet environment or humid
conditions. Working area should be well illuminated. Keep tools away from chemicals and
other corrosive materials.
3. Keep visitors at a safe distance.
4. Electrical tools not in use should be stored away safely.
5. Do not wear loose clothing or jewelry. They can inadvertently get stuck in the moving parts
of the machine, causing injury.
6. Never carry tools by the electric cable. Never unplug by pulling the cable. Keep cables
away from oil, heat and sharp edges.
7. Always check that the pipe and fittings are clamped down tightly.
8. The heating element can reach temperatures in excess of 300°C (570°F). Do not touch the
surface, and keep non-operating personnel at a safe distance.
9. Do not touch facing unit blades while tool is connected to power supply. Activate facing unit
only when it is in the working position.
10. When bringing clamps and pipes together, make sure hands are not between the clamps.
11. Keep tools clean and sharpened. They produce better and safer results. Missing and
worn-out parts should be replaced immediately. Always assure that the accessories are
properly mounted on the machine. Only use factory parts.
12. Always disconnect the machine when not in use, when performing maintenance or when
accessories are being changed.
13. Before connecting to power, check that any accessory tools (e.g. facing unit motor) are
turned off.
14. Always use correct extension cable.
15. Do not use tools and machines when housing or handles, specifically plastic ones, are bent
or cracked. Dirt and humidity in any fracture can lead to electrical shock should the
insulation in the machine be damaged.

Section II - Welding Conditions
1. The welding environment needs to be protected against unfavorable conditions, e.g.
excessive humidity or temperature below 5°C (41°F).
2. It needs to be assured that the pipe wall temperature is adequate for welding. If necessary,
the pipe has to be warmed up or an environmentally controlled welding tent needs to be
erected. If these conditions are met, the welding can be performed at virtually any
environmental temperature. It is advisable to verify the weld quality by making some test
welds at the given conditions.
3. Should the pipe be irregularly heated by intense sunshine, it may be necessary to cover the
pipe ends to be welded so that a balanced temperature is obtained.
4. The pipe ends to be welded must be checked for damage and be free from oil, grease, dirt
and other contaminates. Cleaning the pipe ends must be done just prior to welding.
5. The weld must be kept free from external stresses during the weld process until the material
has sufficiently cooled.
6. The weld process has to be observed continuously. It is recommended to keep a record of
each weld.

Hydraulic Hose Connection & Electrical Connection
A. Use the two hydraulic hoses to connect the base
machine to the hydraulic unit. The non-dripping quick
couplings need to be kept free of dirt. When not in use,
put on the red caps as protection.
⇒
Before disconnecting the hoses, make
sure that there is zero pressure in the hoses. If there is
pressure in the hoses, it will be difficult to re- connect
them.
B. Put heater and facing unit into the storage case.
C. Connect the heating element power cable to the
appropriate outlet on the control box. Also connect the
facing unit and the hydraulic unit to the appropriate
outlets.

Heating Element Temperature Setting
A. The thermostat is located at the top of the control box
beneath a transparent protective cover. Slight pressure
on the front locking devices allows the cover to be
opened and access to the thermostat.
B. Set the thermostat to the appropriate temperature.

Installation of Reducer Inserts
A. 20” Trench Machine
I. For 500 mm pipe and fittings, no inserts are needed.
II. For 450 mm pipe and fittings, the reducer inserts are
mounted directly into the master clamps and secured
with the shorter allen head screws.
III. For pipe and fittings smaller than 450 mm, the insert
clamps must be placed into the 450 mm master
clamps, and then secured with the longer allen head
screws.
B. 12” Trench Machine
I. For 315 mm pipe and fittings, no inserts are needed.
II. For 250 mm pipe and fittings, the reducer inserts are
mounted directly into the master clamps and secured
with the shorter allen head screws.
III. For pipe and fittings smaller than 250 mm, the insert
clamps must be placed into the 250 mm master
clamps, and then secured with the longer allen head
screws.
Note: The ability to weld with the versatile master clamps (connection of one inner master clamp to the
two clamps on the opposite side with the use of the multiple slot connection shaft) allows the combination
of almost any pipe configuration i.e. pipe/pipe, pipe/fitting, fitting/fitting.
For the welding of flanges and eccentric reducers to pipe or fitting, the flange adapter should be placed in
the pipe master clamp and the flange or eccentric reducer centered on the flange adapter.

Preparation For Welding
A. Place the hydraulic unit so that the manometer is easily
visible. Pull the lever to (< >) and hold until the welding
carrier has moved back all the way.
B. Open the clamps and insert the pipe or fittings that are to
be welded, allowing enough space between the pipe
ends for placing the facing unit. Mount the upper clamps
and tighten them with the brass nuts. Small adjustments
for high low can be made by tightening and loosening
the brass nuts. AWS/DVS standards allow a maximum
tolerance of 10% of the wall thickness.
C. Check whether both worked pieces are clamped tight by applying the weld pressure to
ensure that they do not slide back in the clamps.
6.
Facing
A. Place the facing unit onto the machine shafts between
the two pipe ends and lock into place with the safety
lever.
B. With the hydraulic unit, carefully move the welding
carrier into the rotating facing unit. Use the hydraulic
control to adjust the proper pressure for facing. Do not
use too much pressure during the facing process, as this
can burn out the facing unit.

7.
Adjustment of Carrier Movement Pressure (Drag Pressure)
A. Turn the pressure control valve counter clockwise to release the hydraulic pressure.
B. Move the lever on the hydraulic unit in the direction (> <) and slowly turn the pressure
control valve in a clockwise direction until the carrier moves. Read off the pressure at the
manometer (pressure gage on the hydraulic unit). This pressure (referred to as Drag
pressure) must be added to the calculated weld pressure.
C. Bring the pipe ends together and turn the pressure control valve to set the weld pressure
(carrier movement pressure + calculated weld pressure).
⇒
8.
For welding pressures and times, please refer to the welding data charts located
at the end of this instruction manual.
Alignment
A. With the pipe ends together, check for any offset (as described under “Preparation for
welding”). Move the pipe ends apart.
9.
Initial Heating
A. Check the temperature setting of the heating element
(see the charts at the end of this manual for welding
temperatures). Once the heater is at the proper
temperature, place the heating element between the
pipe ends, so that it rests by the heater plate ears on the
shafts.
B. Using the control lever on the hydraulic unit, bring the
pipe ends against the heater while applying the proper
weld pressure.
Asahi/America, Inc.

C. Watch for a continuous bead to form around both pipe
ends (see pipe manufacturer or AWS/DVS standards for
size).
D. Lower hydraulic pressure by either carefully moving lever
or by turning pressure control valve in a counter
clockwise motion.
⇒
10.
Note: If the control lever is moved too far in this
direction, the hydraulic motor will activate and the carrier will open, moving the
pipe away from the heater.
Heat Soak
A. With the pressure almost at zero, begin to time the heat soak process (see welding
parameters). It is important to assure that the pipe ends remain in full contact with the
heating element.
11.
Change Over Time
A. With the hydraulic unit, move the pipe ends apart. Remove the heating element and then
bring the pipe ends back together.
B. Bring the hydraulic pressure back to the original weld pressure. Do not over pressurize,
as this will cause a bad weld. These steps must be performed within the allowable
change over time.
C. In the event that there is hydraulic pressure loss during the welding process, activate the
hydraulic unit to bring the pressure back to the weld parameter as noted in the chart.
12.
Cooling Time
A. Keep the machine under pressure until the cooling time
has expired.
B. For PP and HDPE, Cooling time can be reduced by 50%
under the following conditions:
I.
II.
III.
IV.

Section V - Maintenance
To keep the machine in good working condition, the following should be observed:
1. Keep the hardened chrome guide shafts free of dirt.
2. Assure that the machine is always connected to proper power supply.
3. Keep heating element clean. Whenever necessary, wipe residue off with clean, lint free
cloth while the element is at operating temperature.
4. Keep sufficient oil in the hydraulic tank in order not to damage the pump. Always use
high quality hydraulic oil, commonly used in tractors and construction equipment.
5. All hydraulic quick couplings need to be kept free of dirt by keeping the protective caps
in place at all times.
6. Assure that blades are sharp at all times. The blade design allows for reversal to use
both sides. If necessary, replace blades.
