SAFETY….cont 

8.   A container with unknown contents should be cleaned (see paragraph above), 

DO NOT depend on sense of smell or sight to determine if it is safe to weld or 
cut 

 
9.   Hollow items must be vented before welding or cutting they can explode. 
 
10. Explosive atmosphere. Never weld or cut where the air may contain flammable 

dust, gas or liquid vapors (such as gasoline). 

 

HOSE. 

1.  Use ferrules or clamps designed for the hose (not ordinary wire or other substi-

tute) as binding to connect hoses to fittings. 

 
2.   No copper tubing splices. Use only standard brass fittings to splice hose. 
 
3.   Avoid long runs to prevent kinks and abuse. Suspend hose off ground to keep it 

from being ran over, stepped on, or otherwise damaged. 

 
4.   Coil excess hose to prevent kinks and tangles. 
 
5.  Protect hose from damage by sharp edges, and by sparks, slag, and open 

flames. 

 
6.  Examine hose regularly for leaks, wear and loose connections. Immerse pres-

sured hose in water bubbles indicate leaks. 

 
7.   Repair leaking or work hose by cutting area out and splicing. DO NOT use tape. 
 
8. Never leave Equipment unattended. When not cutting, turn off the equipment. 

DO NOT coil or loop the cutting torch or earth cable around parts of the body. 
Turn unit off when left unattended. 

 
Flash goggles with side shields MUST be worn under the helmet to give some pro-
tection to the eyes should the helmet not be lowered over the face before an arc 
is struck. Prevent looking at the arc momentarily with unprotected eyes (particularly 
at high intensity) as the arc can cause a retinal burn that may leave a permanent 
dark area in the field of vision. 

 
PROTECTION OF NEARBY PERSONNEL 

1.  Warn bystanders not to watch the arc and not to expose themselves to the 

welding-arc rays or to hot metal

  OPERATING INSTRUCTIONS 

 
1. Check all safety instructions have been observed. 
2. Check correct air supply is connected. 
3. Drain any water from bowl on the filter regulator. 
4. Set machine to required current range according to the thickness of metal to 

be cut.  

 DO NOT change range while cutting. 
 
CAUTION: DO NOT attempt to cut material beyond the range specified, as this will 

damage the torch. 

 
1. Check the torch consumables are in good condition. 
2. Check  torch and earth lead connections are tight. 
3. Connect return lead to the work piece, using an area free of rust and paint, for 

a good contact. 

4. Connect to mains supply and switch on. The green light will come on. 
5. Adjust air pressure to  4.5 Bar.  
6. Set the cutting current via the current control, an indication of the setting will be 

shown on the digital display 

7. Adjust the post gas control, if cutting at a high current setting or making a long 

cut set the control near maximum, this will give a longer cool time for the torch. 

8. Place the torch at the edge of the work piece with the center of the tip slightly 

beyond the edge.  Press the torch trigger. The air will flow after a short delay the 
arc will ignite. The torch should be moved steadily along the work piece at a 
rate slow enough for the metal to be cut right through in one pass. If the cut 
penetration is incomplete, then the torch could be damaged. (While the air is 
flowing, check it is still 4.5 Bar.) 

9. When the cut is complete, release the torch trigger button. The arc will immedi-

ately extinguish, but air will continue to flow for a short time. DO NOT turn the 
machine off until this cooling air has stopped flowing as this is necessary to pre-
vent damage to the torch. 

      
PIERCING 

When piercing, the torch head should be angled back so as to allow the mol-
ten material to escape to one side. The normal angle of cut can be resumed 
once the metal has been pierced. 
 NOTE piercing will reduce the life of the torch consumables.
