2. Turvallisuustiedot

Aseta aina turvallisuus etusijalle hitsaus- ja leikkauslaitteita käytettäessä. Turvallisuusohjeiden noudattamatta jättäminen voi johtaa vakaviin vammoihin tai kuolemaan.

• Sähköisku: Voi tappaa. Älä koske jännitteisiä sähköosia. Käytä kuivia, eristäviä käsineitä ja suojavaatetusta. Varmista, että työkappale on maadoitettu asianmukaisesti.
• Höyryt ja kaasut: Voi olla terveydelle vaarallista. Pidä pääsi poissa höyryistä. Käytä tuuletusta tai imua höyryjen poistamiseksi hengitysalueelta.
• Kaaren säteet: Can burn eyes and skin. Wear a welding helmet with a proper shade filter. Wear appropriate eye protection with side shields. Wear protective clothing to cover exposed skin.
• Tuli ja räjähdys: Welding and cutting can cause fire or explosion. Keep flammable materials away from the work area. Have a fire extinguisher readily available.
• Kuumat osat: Voi aiheuttaa vakavia palovammoja. Anna laitteen jäähtyä ennen koskettamista.
• Melu: Liiallinen melu voi vahingoittaa kuuloa. Käytä kuulonsuojaimia.
• Sydämentahdistimet: Persons with pacemakers should consult their doctor before operating this equipment.
• Huolto: Disconnect power before servicing. Only qualified personnel should perform repairs.

5. Asennus

Before operating the PLASMA MULTI 40, ensure proper setup to guarantee safety and optimal performance.

1. Sijoitus: Place the unit on a stable, level surface, ensuring adequate ventilation around the machine. Do not block air vents.
2. Virtaliitäntä: Connect the power cable to a suitable 230V power outlet. Ensure the power supply is stable and can handle the unit's requirements (8 KVA generator recommended if not directly from mains). The unit is designed to tolerate overvoltages of +17%.
3. Maaliitäntä: Kiinnitä maadoitusjohto tukevastiamp to the workpiece or a clean, bare metal part of the work table. A good ground connection is crucial for safety and arc stability.
4. Lisävarusteliitäntä: Connect the appropriate torch (MMA electrode holder, TIG torch, or Plasma torch) to its designated port on the front panel. Ensure all connections are tight and secure.
5. Gas Connection (for TIG/Plasma): For TIG welding and Plasma cutting, connect the appropriate gas supply (e.g., Argon for TIG, compressed air for Plasma) to the unit's gas inlet. Ensure the gas pressure is set according to the specific process requirements.

6. Käyttö

The Stayer PLASMA MULTI 40 offers three distinct operating modes: MMA, TIG, and Plasma Cutting.

6.1. General Operating Principles

• Kytke laite päälle virtakytkimellä.
• Select the desired operating mode (MMA, TIG, or Plasma) using the mode selector.
• Säädä virtaa (amperage) using the adjustment knob according to the material thickness and process.
• Ensure proper personal protective equipment is worn at all times.

6.2. MMA Welding (Shielded Metal Arc Welding)

This mode is suitable for welding with coated electrodes, including cellulosic types. The intelligent STAYER WELDING control enhances performance:

• Kuuma alku: Provides an initial boost of current to ensure easy arc ignition.
• Arc Force: Automatically increases current when the arc length shortens, preventing the electrode from sticking and improving arc stability.
• Tarttumaton: Reduces the current to a minimum if the electrode sticks to the workpiece, allowing for easy removal without damaging the electrode or workpiece.

Connect the electrode holder cable and ground clamp. Insert the appropriate electrode into the holder. Set the current based on electrode diameter and material. Initiate the arc by striking the electrode against the workpiece.

6.3. TIG Welding (Tungsten Inert Gas Welding)

The PLASMA MULTI 40 provides high-quality TIG welding with high-frequency (HF) arc ignition, eliminating the need for scratch starting and reducing tungsten contamination.

Kytke TIG-poltin ja maadoitusjohtoamp. Ensure the inert gas (e.g., Argon) supply is connected and flowing. Install a suitable tungsten electrode in the torch. Select TIG mode and adjust the current. Use the torch trigger to initiate the HF arc and begin welding.

6.4. Plasmaleikkaus

This mode allows for cutting all types of metals with non-contact HF ignition, providing clean and precise cuts up to 12mm thickness.

Kytke plasmapoltin ja maadoitusjohtoamp. Ensure the compressed air supply is connected and flowing at the correct pressure. Select Plasma mode and adjust the cutting current. Position the torch nozzle close to the workpiece without touching (non-contact HF ignition) and press the trigger to initiate the plasma arc and begin cutting.

7. Huolto

Regular maintenance ensures the longevity and optimal performance of your PLASMA MULTI 40 unit.

• Puhdistus: Periodically clean the exterior of the unit with a dry, soft cloth. Use compressed air to blow out dust and debris from the ventilation openings. Ensure the unit is disconnected from power before cleaning.
• Kaapelin tarkastus: Regularly inspect all cables (power, welding, ground, torch) for cuts, cracks, or damaged insulation. Replace any damaged cables immediately.
• Taskulamppujen tarvikkeet: For plasma and TIG torches, regularly check and replace worn consumables (nozzles, electrodes, diffusers, collets) to maintain cutting/welding quality.
• Liitännät: Ensure all electrical and gas connections remain tight and free of corrosion.
• Varastointi: Säilytä laitetta puhtaassa ja kuivassa paikassa, kun sitä ei käytetä.
