2. Safety Information

Operating a plasma cutter involves significant risks. Always adhere to the following safety guidelines to prevent injury or damage to equipment:

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including a welding helmet with suitable shade, safety glasses, flame-resistant clothing, leather gloves, and safety footwear.
• Ventilation: Ensure adequate ventilation to remove fumes and gases produced during cutting.
• Fire Hazards: Keep flammable materials away from the cutting area. Have a fire extinguisher readily available.
• Electrical Safety: Ensure the machine is properly grounded. Do not operate in wet conditions. Inspect cables and connections for damage before each use.
• Compressed Air: Use clean, dry, oil-free compressed air at the recommended pressure.
• Workpiece Safety: Secure the workpiece to prevent movement during cutting. Ensure proper grounding of the workpiece.
• Read Manual: Always read and understand the entire instruction manual before operating the plasma cutter.

3. Unboxing and Package Contents

Carefully unpack all components and verify that all items are present and undamaged. Retain the packaging for future storage or shipping.

3.1. What's in the Box:

• ESAB Thermal Dynamics Cutmaster 58 Plasma Cutter Unit
• Plasma Torch with Cable
• Ground Clamp with Cable
• Air Hose
• Power Cord
• Consumables (e.g., cutting tips, electrodes, nozzles)
• User Manual

4. Setup

Follow these steps to prepare your Cutmaster 58 for operation:

1. Power Connection: Connect the power cord to a suitable power supply (230V single-phase, 16A).
2. Air Supply Connection: Connect the air hose from your compressed air source to the machine's air inlet. Ensure your air compressor provides clean, dry, oil-free air at the recommended pressure (typically 8-9 bar / 116-130 PSI). The machine will use approximately 5-6 bar / 72-87 PSI for cutting.
3. Torch Connection: Connect the plasma torch to the designated port on the front of the machine.
4. Ground Clamp Connection: Attach the ground clamp cable to the machine and securely fasten the clamp to the workpiece, ensuring good electrical contact.
5. Consumable Installation: Ensure the correct cutting tip, electrode, and nozzle are properly installed in the plasma torch.

4.1. Initial Power-Up and Settings:

Turn on the machine. The bright screen will display current settings. Use the control knob to navigate menus and adjust parameters such as amperage and cutting mode (regular or expanded metal). The machine will communicate all necessary information on the screen.

5. Operating Instructions

The Cutmaster 58 offers versatile cutting capabilities. Always wear appropriate PPE before starting any operation.

5.1. Cutting Modes:

• Regular Cutting: Standard mode for solid metal sheets and plates.
• Expanded Metal Cutting: Optimized for cutting mesh or perforated materials. This mode helps maintain the arc across gaps in the material.
• 2T/4T Function: The machine supports 2T (two-touch) and 4T (four-touch) trigger modes. 2T requires holding the trigger for the duration of the cut. 4T allows you to press and release the trigger to start, and press and release again to stop, useful for automated torches or long cuts.

5.2. Piercing and Edge Starting:

The Cutmaster 58 is capable of piercing up to 10mm (approximately 3/8 inch) and edge starting up to 20mm (approximately 3/4 inch) on mild steel. For piercing, hold the torch at a slight angle to allow sparks to escape, then slowly bring it to a vertical position as the arc penetrates the material.

5.3. Cutting Different Materials:

• Mild Steel: The machine provides clean cuts on mild steel.
• Stainless Steel and Aluminum: These materials cut slightly slower than mild steel. The cut surface may appear nitrided or porous due to the compressed air containing oxygen. It is recommended to grind these surfaces before welding.

5.4. Gouging:

Gouging allows for material removal, weld repair, crack preparation, or removing stuck nuts/rivets. To gouge, change to a specialized gouging nozzle (if available) which broadens and softens the arc. Set a shallow torch angle to control depth and prevent sparks from going in unwanted directions. The expanded metal mode setting can also be beneficial for gouging, as it helps maintain the arc even if it stretches.

5.5. Operational Demonstration:

While demonstrating a slightly different model, the operational principles are largely applicable to the Cutmaster 58.

6. Maintenance

Regular maintenance ensures the longevity and performance of your plasma cutter:

• Consumables: Regularly inspect and replace worn cutting tips, electrodes, and nozzles to maintain cut quality and extend torch life.
• Air Filter: Check and clean or replace the air filter in your compressed air system to ensure a clean air supply to the plasma cutter.
• Cables and Connections: Inspect all cables, hoses, and connections for wear, damage, or loose fittings. Replace any damaged components immediately.
• Cleaning: Keep the machine clean and free of dust and debris. Ensure cooling vents are unobstructed.

7. Troubleshooting

If you encounter issues, consult the following common troubleshooting tips:

• No Arc: Check power supply, ground clamp connection, air pressure, and ensure consumables are correctly installed and not worn out.
• Poor Cut Quality: Verify correct amperage and travel speed for the material thickness. Check for worn consumables or insufficient air pressure.
• Error Codes: Refer to the user manual for specific error code meanings and recommended actions.
• Machine Overheating: Ensure adequate ventilation and that cooling vents are clear. Check the duty cycle and allow the machine to cool if necessary.
