2. Safety Instructions

Always prioritize safety when operating plasma cutting equipment. Failure to follow these instructions can result in serious injury or death.

• Electrical Safety: Ensure the machine is properly grounded. Do not operate in wet conditions. Disconnect power before performing any maintenance or changing consumables.
• Eye and Face Protection: Always wear a welding helmet with appropriate shade settings to protect against intense light and UV radiation.
• Body Protection: Wear flame-resistant clothing, gloves, and safety shoes to protect against sparks, heat, and electric shock.
• Ventilation: Ensure adequate ventilation to remove fumes and gases produced during cutting. Avoid inhaling fumes.
• Fire Prevention: Keep flammable materials away from the cutting area. Have a fire extinguisher readily available.
• Compressed Air: Use only clean, dry, oil-free compressed air. Ensure air lines are properly connected and free of leaks.
• Work Area: Keep the work area clean and free of clutter. Ensure stable footing.

5. Adjustment Knob: Used to set amperage, pre-flow, and post-flow times.

3.3. Cutting Torch Components

The PT31 plasma torch consists of several consumable parts that require periodic inspection and replacement.

Figure 3.3: Cutting Torch Components.

1. Ceramic Cup: Directs the plasma arc.
2. Copper Tip: Focuses the plasma arc.
3. Ceramic Ring: Insulates and guides the electrode.
4. Double Sided Electrode: Generates the plasma arc.
5. CUT ON/OFF Trigger: Activates the plasma arc.

4. Setup

Follow these steps to set up your plasma cutter before operation.

1. Connect Air Supply: Attach the gas hose to the air inlet on the rear of the machine. Connect the air compressor filter/regulator to the gas hose and then to your compressed air source. Ensure the recommended gas input pressure of 0.35-0.45Mpa is maintained.

2. Connect Ground Clamp: Securely attach the ground clamp to the workpiece or a clean, bare metal part of the work table. A good ground connection is crucial for safe and effective cutting.
3. Connect Plasma Torch: Connect the PT31 plasma torch to the designated port on the front panel.
4. Power Connection: Connect the machine to a 230V power supply. Ensure the power switch on the rear of the unit is in the OFF position before plugging in.

5. Operation

Once the machine is set up, follow these guidelines for cutting.

5.1. Material Compatibility

The YESWELDER CUT-45D is suitable for cutting a variety of metallic materials.

Figure 5.1: The plasma cutter is suitable for stainless steel, mild steel, copper, and alloy steel.

5.2. Adjusting Settings

• Amperage: Use the adjustment knob to set the desired cutting amperage (20-45A) based on the material type and thickness.
• Pre-flow Time: Adjust the pre-flow time (0.1-2s) to allow air to flow before the arc starts, which helps to clear the cutting path.
• Post-flow Time: Adjust the post-flow time (2-20s) to cool the torch and consumables after cutting, extending their lifespan.

5.3. Cutting Procedure

1. Turn on the plasma cutter.
2. Set the appropriate amperage, pre-flow, and post-flow settings for your material.
3. Position the torch nozzle close to the workpiece.
4. Press the trigger on the torch to initiate the pilot arc.
5. Once the arc transfers to the workpiece, move the torch steadily along the desired cut line. Maintain a consistent speed and standoff distance.
6. Release the trigger to stop cutting. The post-flow air will continue to cool the torch.

5.4. Cutting Capacity

The machine offers specific cutting capabilities based on material thickness.

• Nominal Clean Cut: Up to 6 mm thickness.
• Maximum Severance Cut: Up to 12 mm thickness.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your plasma cutter.

• Consumable Inspection: Regularly inspect the ceramic cup, copper tip, ceramic ring, and electrode for wear. Replace them when signs of damage or excessive wear are visible.
• Air Filter: Check and drain the water trap on the air filter/regulator regularly. Replace the filter element if it becomes clogged or damaged.
• Cleaning: Keep the machine and torch clean and free of dust and metal particles. Use compressed air to blow out internal components if necessary (with power disconnected).
• Cable Inspection: Periodically check all cables (power, torch, ground) for damage, cuts, or frayed insulation. Replace damaged cables immediately.
