STAHLWERK CUT 50 ST IGBT Plasma Cutter User Manual

1. Introduction

This manual provides essential information for the safe and effective operation of your STAHLWERK CUT 50 ST IGBT Plasma Cutter. Please read it thoroughly before use and keep it for future reference. This device is designed for cutting all electrically conductive metals, including standard steel, copper, stainless steel, brass, aluminum, and titanium. It is also suitable for cutting painted sheets and those with flash rust.

2. Safety Instructions

WARNING: Plasma cutting involves high voltage, high temperatures, and intense light. Failure to follow safety precautions can result in serious injury or death.

2.1 Personal Protective Equipment (PPE)

• Eye Protection: Always wear a welding helmet with appropriate shade filter.
• Body Protection: Wear flame-resistant clothing, gloves, and sturdy footwear.
• Respiratory Protection: Ensure adequate ventilation or use a respirator to avoid inhaling fumes.

2.2 Electrical Safety

• Ensure the power supply matches the machine's requirements.
• Do not operate in wet conditions.
• Regularly inspect cables and connections for damage.
• Always disconnect power before performing maintenance or changing parts.

2.3 Fire and Explosion Hazards

• Keep flammable materials away from the cutting area.
• Do not cut containers that have held flammable substances.
• Have a fire extinguisher readily available.

2.4 Work Area

• Ensure the work area is well-ventilated.
• Keep bystanders away from the cutting zone.
• Secure the workpiece to prevent movement during cutting.

4. Setup

4.1 Unpacking and Inspection

• Carefully remove all components from the packaging.
• Inspect for any shipping damage. Contact your supplier immediately if damage is found.
• Ensure all listed components are present.

4.2 Connecting the Air Supply

• Connect the air pressure regulator with water separator to the air inlet on the rear of the plasma cutter.
• Attach the air hose from your compressor to the air pressure regulator.
• Set the air pressure according to the material thickness (refer to Section 5.2).

4.3 Connecting the Plasma Torch

• Connect the AG-60 plasma torch to the designated connector on the front panel. Ensure a secure connection.

4.4 Connecting the Ground Clamp

• Connect the ground clamp cable to the appropriate terminal on the front panel.
• Attach the ground clamp securely to the workpiece or a clean, bare metal part of the work table. A good ground connection is crucial for effective cutting.

4.5 Power Connection

• Connect the power cable to a suitable power outlet (230V, 50/60Hz). Ensure the outlet is properly grounded and capable of handling the required amperage.

5. Operating Instructions

5.1 Powering On

• Ensure all connections are secure.
• Turn on the main power switch located on the rear of the unit.
• The digital display on the front panel will illuminate.

5.2 Setting Cutting Parameters

• Adjust the amperage using the rotary knob on the front panel. Refer to the table below for recommended settings.
• Adjust the air pressure using the regulator. Optimal pressure ensures a clean cut and extends consumable life.

Note: These are general guidelines. Optimal settings may vary based on material type and desired cut quality.

5.3 Initiating a Cut (HF Ignition)

• Position the torch nozzle close to the workpiece (contact ignition).
• Press the trigger on the plasma torch. The HF ignition will create a pilot arc.
• Once the pilot arc is established, move the torch steadily along the desired cut line.
• Maintain a consistent speed and distance from the workpiece for a clean cut.

5.4 Post-Cut Procedure

• Release the torch trigger to stop the arc.
• The automatic air post-flow will continue for a short period to cool the torch and consumables.
• Turn off the plasma cutter's main power switch when finished.
• Disconnect the power and air supply.

6. Maintenance

6.1 Consumable Replacement

• Regularly inspect the nozzle, electrode, and ceramic cap for wear. Replace them when signs of damage or excessive wear are visible to ensure optimal cutting performance.
• Always ensure the machine is powered off and cooled down before changing consumables.

6.2 Air Filter Maintenance

• Periodically check and drain the water separator on the air pressure regulator.
• Clean or replace the air filter element as needed to ensure a clean and dry air supply.

6.3 General Cleaning

• Keep the plasma cutter unit clean and free from dust and metal particles.
• Use compressed air to clean the internal components, especially after heavy use, as recommended by the manufacturer. Ensure the power is disconnected.

7. Troubleshooting

• No Arc: Check power connection, ground clamp connection, air pressure, and torch consumables. Ensure the workpiece is clean and conductive.
• Poor Cut Quality: Verify correct amperage and air pressure settings for the material thickness. Inspect consumables for wear. Adjust cutting speed.
• Overheat Indicator: If the overheat light illuminates, the machine has exceeded its duty cycle. Allow it to cool down with the power on (fan running) before resuming operation.
• Air Flow Issues: Check air compressor, air hose for kinks, and water separator for excessive moisture.

For persistent issues, contact STAHLWERK customer support.
