4. Fit the gas Y-pieces
onto the main unit and connect the 600 mm (24”) and 900 mm (36”) hoses from the
distributor to the two torches.
5. Fix the weight bar and weight.
6. When the torch stroke in insufficient to cut the plate beneath the rail when carrying out lower-edge preparation,
change the torch holders to the position indicated by the arrow.
4.03 PREPARATION FOR OPERATION
1. After fixing the nozzle to the torch, adjust the gas pressure to the standard settings shown in the Cutting Data
(see page 19). (Confirm first that all torch valves are closed.)
2. Ensure the switch on the machine is OFF and connect the power cord to the body and power supply.
3. Refer to the Cutting Data to find the correct cutting speed.
4.04 OPERATION
1. Align the nozzle with the scribed cutting line.
2. Open the fuel gas valve, slightly open the preheat oxygen valve and ignite the torch with the lighter. Next, fully
open the gas valve and adjust the preheat oxygen valve to obtain a neutral flame.
3. Adjust the distance between the nozzle and plate. (This distance should be ~2-3 mm from the white tip of the
flame.)
4. Engage the clutch, and after sufficiently preheating the plate, open the cutting oxygen valve and put the direction
switch forward or reverse to start cutting.
5. After cutting has started, observe the condition of the cut carefully and adjust the cutting speed to the optimum
level.
6. When cutting has finished, close the cutting oxygen valve, turn off the direction switch, close the fuel gas valve,
then the preheat oxygen valve and return the clut
ch to the “stop” position.
Note: Check that the flow of cutting oxygen is at right-angles to the plate. For a proper cut, base gas pressures in
accordance with the settings given in the Cutting Data (see page 19). However, carry out pressure corrections in
accordance with the cutting conditions.
