BEAVER
HANDY AUTOMATIC GAS CUTTING MACHINE
KOIKE SANSO KOGYO CO.,LTD.
The BEAVER is a portable automatic gas cutting machine of a unique structure, which wins success in two different functions
– that is running stability of straight line cutting and tracing accuracy of curved line cutting.
Moreover with an optional auto-stop function, the operator does not need any more to watch the rail ending point, as the autostop function acts to stop the running operation and gas supply at the rail end. Try our the BEAVER, and you will see why we
call it unique, how well it works, how easily it can be operated.
specifications
Best cutting of straight and curved line by shifting guide
wheel
For the straight and curved line cutting, the point is the
distance between the guide wheel and the driving wheel.
On straight line cutting, the longer the distance is, the
better the running stability is: while on curved line cutting,
the shorter the distance is, the better the curve tracing
accuracy is. Therefore, as its unique structure, the
BEAVER resolves the problem by shifting the guide wheel
and succeeds in getting both running stability op straight
line cutting and tracing accuracy of curved line cutting.
On curved line cutting, attach the guide wheel to the front,
while on automatic straight line cutting, attach it to the
rear.
Easy to operate
The grip of the BEAVER is of a pistol shape and fits
operator’s hand well. A trigger type clutch a speed control
dial under the clotch are operated by a index finger. The
thumb operates a power switch and jet oxygen lever. Thus
the operator can control all functions by a single hand.
Standing type – needs little space to keep
When BEAVER is not operated, it can be stood with its
grip upward. Therefore BEAVER saves the space to keep
it, and makes it easy to clean the tip (see photo 2).

5 Cutting Operation
Strictly observe the safety rules, precautions and instructions to ensure
safety during gas cutting operations. Operators and supervisors MUST
keep safety in mind.
5.1 Safety measures prior to operation
5.1.1 Selection of tip
Referring to the Cutting Data, select the suitable tip according to the plate
thickness.
For a heavily rusted plate or a bevel cutting angle of more than 20°, select
the tip one grade higher than the one shown in the Cutting Data.
5.1.2 Operation of running direction changeover switch
Power switch operation
Danger
Be sure to check that the power
switch is in the stop position
before turning on the power. If the
power switch is on, it is dangerous
to start the machine.
Never put your hand between the
machine and the rail when the
machine is running; otherwise your
hand may be caught between
them.
1 Operate the power switch for
start-stop changeover.
2 Be sure to set it in the stop
position unless the machine is to
be moved.
figure 5 - 1
5.2 Ignition and flame adjustment
Adjust the gas pressure according to the Cutting Data. The data shows
the pressure when all the valves are open. Readjust the pressure after
ignition.
21
BEAVER
Flame adjustment method
1 Open the fuel gas valves ¼ to ½ a turn.
2 Light the torch with an igniter.
3 Open the preheating oxygen valve gradually until a white cone of the
standard flame has been obtained. The incandescent area should be
uniform and about 5 - 6 mm in length.
4 Open the jet oxygen valve fully.
5 Readjust the flame if its condition has changed.
A disorderly flow of the jet oxygen will adversely affect the quality of the
cutting surface. In such a case, the jet oxygen channel has to be cleaned.
1 Close both the gas and the preheat oxygen valves before cleaning
the jet oxygen opening.
2 Clean the tip with a suitable cleaning needle while the jet oxygen is
flowing.
Appropriate distance between the tip and the cutting surface:
- Acetylene gas: 8-10 mm
- LPG gas:

Neutral flame ensures a good quality cut surface. (Oxidized flames may be
used for bevel cutting.) The oxidized flame shortens the jet oxygen flow,
causing slug deposition or melting the upper edge of the cut surface and
causing other adverse effects on the cut surface. Excessively high jet
oxygen pressure will cause the same effect.

5.3 Cutting and piercing method
• Cut in from the end of steel plate.
• Pierce steel plate before cutting.
• Drill a hole before cutting.
22
BEAVER
Piercing method
1 Ignite and adjust the flame.
2 Thoroughly preheat the cut-in point until it is white hot.
3 Open the jet oxygen valve to pierce the steel plate. The tip should be
about 15 - 20 mm from the plate to prevent slag from splashing onto
the tip and adhering there, which will shorten the working life of the
tip.
5.4 Procedures for starting cutting operation and
extinguishing the flame
1 Align the tip with the cutting start point, ignite, and then adjust the
flame.
2 Sufficiently preheat the cutting start point.
3 After heating, supply cutting oxygen and turn the handle
simultaneously to begin cutting.
4 Carefully check the cutting condition and turn the handle to set an
optimum cutting speed. For the cutting speed, refer to chapter 10.
5 Extinguish the flame after cutting as follows:
a Turn off the motor switch (or turning direction switch).
b Close the jet oxygen valve.
c Close the preheating oxygen valve.
d Close the fuel gas valve.
5.5 Safety measures against backfire and flashback
5.5.1 Prevention of backfire
Warning
Backfires may cause serious accidents or fires. Be careful to prevent
such disaster.
When a backfire occurs, find the cause and inspect and maintain the
machine correctly before using the machine again.
The following are causes of backfire:
1 Improper gas pressure adjustment.
2 Overheated tip.
3 Slag clogged in tip.
4 Damage to the tapered section of the tip or torch.
23
BEAVER
5.5.2 Prevention of flashback
Warning
Flashback could cause fire and break the machine.
Should there be a hissing sound in the torch, quickly take the following
action:
1 Close the preheating oxygen valve.
2 Close the fuel gas valve.
3 Close the jet oxygen valve.
Should flashback occur, find the cause and take appropriate action before
using the machine again.
5.6 Cutting operation
1 Attach the rail to the cutting position and align the tip with the
cutting start point.
2 Hold the clutch to free the machine and turn on the power switch.
3 Simultaneously with opening the cutting oxygen valve, turn on the
switch to start cutting.
4 Incline the JOX lever to let the cutting oxygen out and release the
machine simultaneously to run the machine.
5 After cutting, turn off the switch and close the cutting oxygen valve,
fuel gas valve and preheating oxygen valve in this order.
6 Thereafter repeat operations from step n1.
5.6.1 Straight cutting
Optional rails are used in most of the cases.
1 Align the rail parallel to the planned cutting line approx. 80 ~ 100 mm
away from it. Cutting length can be extended freely with extension
rails.
2 Pinch both sides of the rail by the two wheels of the machine on.
3 Turn the guide wheel toward the resistor.
4 Fit it to the centre groove of the rail.
5 Set the torch to the starting point of the cutting.
6 Ignite the torch.
7 Adjust the flame.
8 Heat the starting point thoroughly and push the jet oxygen lever and
the power switch with the thumb.
9 Adjust the cutting speed by the speed adjustment dial according to
the cutting station.
24
BEAVER
The jet oxygen valve should be open completely in advance when it is
actuated. When the gas pressure is high to cut a thin plate, use this valve
to reduce the pressure in order to make the cutting operation easy.
Caution
Be sure not to leave any dust and if there is any remove it
immediately. If there is any large dust or spatter on the rail, the
machine will suffer from knocking there and it will cause the damage
of the cutting surface.
Caution
Be careful not to allow the hoses catch on the plates edge.
5.6.2 Manual guide cutting
1 Do the marking off on the plate surface and make a punch mark
wherever curved and straight lines join.
2 While shifting the machine handle, approach the tip to the position
30 ~ 50mm from the side of the drive wheel.
3 Free the guide wheel by pulling the clutch lever with a forefinger and
move the machine to the cutting start point.
4 Arrange hoses so that they will not bother the cutting operation.
5 Heat the starting point thoroughly.
6 Open the jet oxygen lever by the thumb.
7 Turn the power switch immediately and guide the machine by hand
so that the tip trace the marking off line.
8 Let the machine run only by the drive motor (do not pull or push the
machine forward) and give the machine only the direction by hand.

BEAVER
Caution
Do not handle the machine abruptly because smooth cutting surface
will then not be achieved. Be watchful to obtain a smooth cutting
surface and prevent the machine from vibrating.
When the cutting operation is over, shut the valves in the following order:
• Jet oxygen valve
• Fuel gas valve
• Preheat oxygen valve.
Small radius corner cutting
1 Bring the torch close to the drive wheel.
2 Keep a forefinger on the speed adjustment dial in order to increase
or decrease the speed whenever the torch approaches the corner.
3 When the torch runs through out the corner, reset the speed to the
previous one.
4 On the inside cutting of the corner with a radius less than 50 mm,
reduce the speed until the motor stops at the starting point of the
curve.
5 Guide the machine by hand and start the motor again at the ending
point of the curve.
Sharp corner cutting
1 When the torch reaches the corner, close the jet oxygen lever and
pull the clutch lever at the same time.
2 Turn the machine to the new direction so that the tip centre fits the
marking off line.
3 Preheat again.
4 Open the jet oxygen lever.
5 Release the clutch and resume the cutting.
Note: Exercise to be skilled in performing the hand guide cutting.
Manual guide cutting requires a certain period to be skilled. If
preferred, to fix the guide wheel is another method for easier tracking
of the marking off line.
5.6.3 Ordinary circle cutting
Ordinary circle cutting is performed as follows:
For the hole cutting, follow diagram I and for the circumference cutting
diagram II. For both operations pierce the point P first and cut forward by
the cross bar handle until the tip reaches the marking off line.
26
BEAVER
Caution
For the small circle cutting, increase the speed, but it may not be
possible to cut a very thin plate because of the speed limitations.
Radius limit of the machine with the standard equipment is: minimum
50 mm, maximum 550 mm.
How to pierce
1 Ignite a torch.
2 Adjust the flame.
3 After heating the point until it has become quite incandescent, push
the jet oxygen valve to get the cutting oxygen and the hole will be
produced quickly.
To avoid the slag fouling the tip, use the up and down handle of the torch
holding bracket to lift the torch about 10 mm.
5.6.4 Optional circle cutting
Setting of the machine is different in large and small circle cutting. See the
diagram and set the optional equipment as follows.
Note: Set the corner so that it lies on the prolongation of the driving
wheel axis.
