WARNINGS – SAFETY REGULATIONS
www.gys.fr
GENERAL INSTRUCTIONS
The instructions in this user manual must be read and understood before operating the machine.
Do not undertake any modifications or maintenance work that is not included in the user manual.
The manufacturer shall not be liable for any damage to persons or property resulting from using the product in a manner not in accordance with the instructions in this user manual.
If there are any problems or queries, please consult a qualified technician to properly set up the equipment.
PROTECTING YOURSELF AND OTHERS
Cutting metal can be dangerous and cause serious injury or death.
Cutting metal exposes individuals to a dangerous heat source, light radiation from the arc, electromagnetic fields (attention those with pacemakers), risk of electrocution, noise and gas fumes.
Follow the following safety guidelines to protect yourself and others:
 |
Wear the appropriate clothing to protect yourself from burns and radiation: cuffless, insulated, dry, flame-retardant clothing in good condition that covers the whole body. |
 |
Wear gloves that ensure electrical and thermal insulation. Use a protective welding and cutting curtain and/or a cutting hood with a sufficient protection level (varies according to the application). Protect your eyes during cleaning operations. Contact lenses are strictly prohibited. |
 |
It is sometimes necessary to delimit areas using fireproof curtains to protect the cutting area from arc rays, spatter and incandescent waste. Inform people in the cutting area not to look at the arc rays or the melted parts, also advise them to wear the appropriate clothing to protect themselves. |
 |
Use noise-cancelling headphones if the cutting process reaches a noise level above the permitted level (these headphones should be offered to anyone in the cutting area). Keep hands, hair and clothes away from moving parts (fans). Never remove the protective casing from the cooling unit when the power source is switched on as the manufacturer cannot be held responsible in the event of an accident. |
 |
Freshly cut parts are hot and can cause burns if handled. When servicing the torch, ensure that it is cool enough by waiting for at least ten minutes before undertaking any maintenance work. The cooling unit must be switched on when using a water-cooled torch to ensure that the liquid does not cause burns. It is important to secure the work area before leaving it; this is to protect people and property. |
CUTTING FUMES AND GASES
The fumes, gases and dusts emitted by cutting processes are hazardous to one’s health. Sufficient ventilation must be provided and an additional air supply may be necessary. An air-fed mask could be an appropriate solution if the ventilation is inadequate.
Check that the suction is effective by checking it against safety standards.
Warning: cutting in confined spaces requires remote monitoring for safety. Furthermore, the cutting of certain materials that contain lead, cadmium, zinc, mercury or even beryllium, can be particularly harmful; it is important to degrease parts before cutting them.
Gas cylinders should be stored in an open or well-ventilated area. They must be in an upright position and secured to a stand or trolley. Cutting applications should not be carried out near grease or paint.
FIRE AND EXPLOSION HAZARD
The cutting area must be fully protected; flammable materials should be kept at least 11 metres away.
Fire-fighting equipment must be available in the vicinity of cutting operations.
Beware of hot substances or sparks being projected, even through cracks; these can cause a fire or explosion.
Keep people, flammable objects and pressurised containers at a safe distance.
Cutting in closed containers or tubes should be avoided; if they are open, they should be emptied of any flammable or explosive material (oil, fuel and gas residues, etc.).
Grinding operations must not be directed towards the cutting current’s source or any flammable materials.
ELECTRICAL SAFETY
Electric shocks can cause serious direct or indirect accidents and even death.
Never touch the torch’s live parts because it is connected to the cutting circuit.
Do not touch the torch and the earth clamp at the same time.
Always use dry and undamaged clothing to insulate yourself from the cutting circuit. Wear insulated footwear, regardless of your working environment.
CAUTION FOR USE
Never wrap the torch cables around your body.
Do not use the torch to move the source of the cutting current.
The torch must be completely unwound in order to avoid overheating.
Switch off the power source after the torch has cooled down before any maintenance work and before replacing or checking worn parts.
Regularly check the torch’s condition. It must be replaced if it becomes damaged.

SETTING UP
TORCH CONNECTION REQUIREMENTS
The power source must be turned off.
- To assemble the handle bundle with an EASYFIT torch, insert the torch connector (A) into the bundle socket and screw on part B. Tighten the torch.
- Connecting the torch to the power source:
Insert the handle bundle connector (A) into the power source’s female bundle socket (C) and screw on part B. Tighten the torch.
*Step 1 is only for EASYFIT torches.
TORCH EQUIPMENT
The torch must be fitted with the correct consumables, chosen according to the application and the set current.
Choosing the incorrect consumable will result in cutting defects, premature wearing of the consumables and could even cause the entire unit to malfunction. The torch is supplied with a pot of silicone grease to minimise the seal’s wear and the seizing of metal parts. It is recommended to apply this grease regularly.
Consumables
Regularly check the condition of the protective nozzle, the contact tip and the electrode for wear and tear, also check these parts if the cutting speed is significantly reduced. It is advisable to replace the nozzle’s contact tip and the electrode at the same time.

DEFECT SOURCE
| CONSUMABLES | Consumables are wearing parts, so it is important to know when to change them. Visually: melted or damaged consumables, holes in nozzles >1.5 mm, worn electrodes or melted pads, etc. Pragmatically: loss of cutting performance, ignition on difficult workpiece, etc. |
| NOZZLE | Tighten the nozzle so that all parts are securely fastened. The nozzle must not rotate easily. |
| GAS | Use compressed air with an oil and water filtration system. |
ANOMALIES, CAUSES, SOLUTIONS
| SYMPTOMS | POSSIBLE CAUSES | SOLUTIONS |
| No arc ignition. | Torch incorrectly connected to the power source. | Check the torch’s conenction to the power source. |
| Incorrect compressed-air pressure. | Adjust the air pressure to the recommended value. | |
| Missing consumable part (nozzle, contact tip electrode or diffuser, etc.). | Replace missing parts. | |
| Consumables are not installed correctly. | The electrode is not in contact with the contact tip. | |
| Interrupting the cutting arc. | Earth clamp not properly connected (if disconnected after a few seconds of cutting). | Check that the earth clamp is connected to one of the sheet metal’s clean surfaces to be cut effectively. |
| Inappropriate cutting-feed speed. | Adjust the cutting speed. | |
| The distance between workpiece and torch’s nozzle is too great. | Bring the torch closer to the workpiece. | |
| The compressed-air supply has been cut off. | Check the compressed-air supply. | |
| Damaged consumable in the torch. | Inspect the torch’s consumable parts and replace them. | |
| The consumables are wea- ring prematurely. | Insufficient air pressure. | Adjust the air pressure. |
| The cutting-feed speed is too fast. | Adjust the cutting speed. | |
| Impurities or moisture in the compressed air. | Check the power source’s air filter. | |
| Soiled cutting surface. | Clean and strip the surface of the sheet metal to be cut. | |
| Excess burrs under the workpiece after cutting. | The cutting-feed speed is too fast. | Adjust the cutting speed. |
| Incorrect compressed-air pressure. | Adjust the air pressure to the recommended value. | |
| The cutting current is too low for the thickness of the workpiece. | Adjust the cutting current value on the power source. | |
| Not perpendicular to the metal sheet’s surface. | Torch not held perpendicular to the surface of the workpiece. | Improving torch support. |
| Consumables incorrectly fitted in the torch (loose nozzle, etc.). | Readjust the fitting and tightening of consumables. | |
| The cutting current is too low for the thickness of the workpiece. | Adjust the cutting current value on the power source. |
