1. Introduktion

The Stayer PLASMA MULTI 40 is an advanced electronic inverter equipment designed for electric arc welding and cutting. This versatile unit offers three primary functions: MMA (Shielded Metal Arc Welding), high-quality TIG welding, and plasma cutting for various metals. Engineered for both light and medium maintenance and construction tasks, it prioritizes maximum quality, ease of use, and reliability.

Key features include intelligent STAYER WELDING control with Hot Start, Arc Force, and Anti Stick for optimized arc ignition and stability, robust construction exceeding European specifications, and high-quality components like 600V IGBT switches. Weighing only 7kg, it is among the lightest in its category, offering maximum power density.

2. Sikkerhedsoplysninger

Always prioritize safety when operating welding and cutting equipment. Failure to follow safety guidelines can result in serious injury or death.

• Elektrisk stød: Kan dræbe. Rør ikke ved strømførende dele. Brug tørre, isolerende handsker og beskyttelsestøj. Sørg for, at emnet er korrekt jordet.
• Røg og gasser: Kan være sundhedsfarligt. Hold hovedet væk fra dampene. Brug ventilation eller udsugning til at fjerne dampe fra indåndingszonen.
• Bue stråler: 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.
• Brand og eksplosion: Welding and cutting can cause fire or explosion. Keep flammable materials away from the work area. Have a fire extinguisher readily available.
• Varme dele: Kan forårsage alvorlige forbrændinger. Lad udstyret køle af, før du rører ved det.
• Støj: Overdreven støj kan skade hørelsen. Brug høreværn.
• Pacemakere: Persons with pacemakers should consult their doctor before operating this equipment.
• Opretholdelse: Afbryd strømmen før service. Kun kvalificeret personale bør udføre reparationer.

5. Opsætning

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

1. Placering: Place the unit on a stable, level surface, ensuring adequate ventilation around the machine. Do not block air vents.
2. Strømtilslutning: 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. Jordforbindelse: Fastgør jordforbindelsen sikkertamp 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. Tilbehørsforbindelse: 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. Betjening

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

6.1. General Operating Principles

• Tænd for enheden ved hjælp af strømafbryderen.
• Select the desired operating mode (MMA, TIG, or Plasma) using the mode selector.
• Juster strømmen (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:

• Hot Start: Giver en indledende strømforøgelse for at sikre nem lysbuetænding.
• Arc Force: Automatically increases current when the arc length shortens, preventing the electrode from sticking and improving arc stability.
• Anti-klæbende: 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.

Tilslut TIG-brænderen og jordforbindelsenamp. 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. Plasma Cutting

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

Connect the plasma torch and ground clamp. 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. Vedligeholdelse

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

• Rensning: 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.
• Kabelinspektion: Regularly inspect all cables (power, welding, ground, torch) for cuts, cracks, or damaged insulation. Replace any damaged cables immediately.
• Brænder forbrugsstoffer: For plasma and TIG torches, regularly check and replace worn consumables (nozzles, electrodes, diffusers, collets) to maintain cutting/welding quality.
• Forbindelser: Ensure all electrical and gas connections remain tight and free of corrosion.
• Opbevaring: Opbevar enheden et rent og tørt sted, når den ikke er i brug.
