well as reduce the flow resistance.
1.2.5 Safety precautions for fire
Take safety precautions to prevent fire prior to gas cutting.
Ignoring hot metal, sparks, and slag could cause a fire.
1. Keep a fire extinguisher, fire extinguish sand, bucket full of water, etc. ready on the site where gas
cutting is performed.
2. Keep flammables away from the cutting area to avoid exposure to sparks.
3. Always cool down steel plates that have become hot after cutting, as well as hot cut parts or scrap,
before bringing them close to flammables.
4. Never cut containers to which flammable materials are stuck.
1.2.6 Safety precautions for skin burns
Observe the safety precautions to prevent skin burns. Ignoring heat, spatter, and sparks during
operation could cause a fire or burned skin.
1. Do not perform cutting near flammables. (Move flammables well away from the sparks.)
2. Do not cut containers filled with flammables.
3. Do not keep lighters, matches, and other flammables nearby.
4. Flames from the torch will burn the skin. Keep your body away from the torch and tip, and check
the safety before operating the switches and valves.
5. Wear the correct protectors to protect your eyes and body.
6. Correctly tighten the tip to prevent backfire.
● When fixing a tip to the torch, tighten the nut with the two wrenches attached.

4.3.3 Determination of number of chains
The relationship between the pipe O.D. and the number of chain is as follows.
Y=X+11
where,Y = the number of chains
X = pipe O.D. (unit:cm; Round off the value in mm to the next value in cm.)
For example, pipe O.D. 114.3mm 11.43cm 12
Y = X+11
= 12+11
= 23
Therefore, about 23 chains are necessary.
4.4 Securing machine to pipe
1. Calculate the necessary number of chains, place the main unit on the pipe to be cut and turn the
tightening handle counterclockwise to lower the side bracket.
2. Engage the chain with the sprocket and attach the chain as shown in the figure to set it on the
pipe. (Do not confuse the right side of the chain with its wrong side. Rounded side faces to the
pipe.)
3. Turn the tightening handle clockwise and fix the main unit to the pipe. When turning the
tightening handle, exercise care so that the spring will not be in close contact, leaving a
clearance of 1-2mm.
4. To avoid a chain engagement error or chain loosening, hold the machine by hand and turn the
handle to the right and left within the range of approx. 120 degrees two or three times,
tensioning the chain gradually.
5. After setting, turn the handle by one turn and check to see if the hose length is sufficient and the
cutting tip returns to the original position.
5 Cutting operation
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 for a bevel cutting angle of more than 20 degree, select the tip one
grade higher than the one shown in the Cutting Data.

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.
■ Flame adjustment method
1. Open the fuel gas valve 1/4 to 1/2 a turn and light the torch with an igniter.
2. Then, 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 (3/16-1/14
″ )in
length.)
3. Open the jet oxygen valve fully. 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, clean the
tip with a suitable cleaning needle while the jet oxygen is flowing.
4. Appropriate distance between the tip end and cutting surface:
Acetylene gas 8-10 mm
LPG gas 5-8 mm
Neutral flame ensures a good quality cut surface. (Oxidized flames may be used for bevel
cutting.)
The oxidized flame shortens the cutting oxygen flow, causing slug deposition or melting the
upper edge of the cut surface. Excessively high cutting oxygen pressure will cause the same
effect.
5.3 Cutting and piercing method
1. Cut in from the end of steel plate.
2. Pierce steel plate before cutting.
3. Drill a hole before cutting.
■ Piercing method
1. Ignite and adjust the flame.
2. Thoroughly preheat the cut-in point until it is white hot.
3. Open the cutting 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.
