5.2 Assembling the Unit (for a Single Torch Set)
1. Take the unit body out of the packing box.
2. Fit the primary hose to the gas distributor.
• Blue hose (oxygen)
• Red or orange hose (acetylene or LPG)
3. Fit the arm support (set) to the stand and insert the pipe arm into the arm support (set).
4. Insert the torch holder (set) into the pipe arm.
5. Connect the hoses to the distributor and insert them into the stand.
※
When fitting the hoses, check their individual engraved marks and colors: the cutting
oxygen (JO) is blue, the preheating oxygen (PO) is blue, and acetylene gas and LPG (AC,
LPG) are red or orange.
6. Connect the torch, three single valves (set) and hoses, and insert them into the torch
holder.
5.3 Preparation for Work
5.3.1 Connecting the cabtire cable
1. Connect the cabtire cable to the unit body.
2. Connect the metal plug on the cabtire cable to the metal receptacle on the unit side. Make sure
that there is no foreign object or debris before plugging it in.
3. The metal receptacle is fitted with screws. Be sure to tighten the screws in order to prevent
the plug coming out while the unit is traveling.
* When turning on the power supply after turning off the unit body, leave an interval of around
three seconds.
5.3.2 Connecting a nozzle
Select the appropriate nozzle from the nozzle capacity standard table according to the
thickness of the steel plate to be cut.
Use the top nozzle number in the standard table when the steel plate is very rusty or the
groove angle is greater than 20 degrees.
(Nozzle No. “00” or “0” is indicated.)
5.3.3 Connecting the nozzle
1. Select a nozzle according to the thickness of the material to be cut and fit it to the torch.
Refer to the nozzle capacity standard table for selection of the nozzle.
• Be sure to securely tighten the nozzle using two spanners when fitting the nozzle on the
torch.
• If the nozzle is tightened too firmly, it is heated up during cutting, which can further tighten it
and make it difficult to remove.
• Do not scratch the mounting taper of the nozzle. This will cause backfiring.
