4. Setup

Proper setup is crucial for safe and effective operation. Ensure the machine is placed on a stable, level surface in a well-ventilated area.

4.1 Power Connection

1. Verify your power supply matches the machine's dual voltage capability (110V/220V). The machine automatically detects the input voltage.
2. Connect the power cord to a suitable grounded outlet.

4.2 Plasma Cutter Setup

1. Connect the plasma torch to the designated port on the front panel.
2. Attach the ground clamp to the workpiece, ensuring good electrical contact.
3. Connect an air compressor to the air inlet on the rear of the machine. Ensure the air supply is clean, dry, and regulated to the recommended pressure (refer to specifications).

4.3 MIG Welder Setup (Flux Core Gasless)

1. Open the wire feed compartment.
2. Install the flux core welding wire spool onto the spindle, ensuring it rotates freely.
3. Thread the welding wire through the guide tube and into the drive rollers. Adjust the drive roller tension to prevent slipping or crushing the wire.
4. Feed the wire through the MIG torch liner until it exits the contact tip.
5. Connect the MIG torch to the appropriate port.
6. Attach the ground clamp to the workpiece, ensuring good electrical contact.

5. Operating Instructions

Familiarize yourself with the control panel and settings before beginning any operation.

5.1 Plasma Cutting Operation

1. Turn on the machine and select the 'AIR CUT' mode.
2. Adjust the cutting current (Amps) based on the material thickness. The LED display will show the current settings.
3. Ensure proper air pressure is supplied.
4. Position the plasma torch nozzle approximately 1/8 inch (3mm) above the workpiece.
5. Press the torch trigger to initiate the pilot arc and begin cutting. Maintain a steady travel speed for a clean cut.
6. Recommended nozzle (tip) size: 1.0mm/0.39inch for best cutting results.
7. Cutting Thickness: Up to 3/4'' @220V (1/2''@110V). Ideal clean cut thickness: 1/3''@110V, 1/2''@220V.

5.2 MIG Welding Operation (Flux Core Gasless)

1. Turn on the machine and select the 'MIG' mode.
2. Use the synergy control feature: Select the wire size and adjust the current knob. The machine will automatically set the appropriate wire feed speed and voltage.
3. Ensure the ground clamp is securely attached to the workpiece.
4. Position the MIG torch at the desired starting point.
5. Press the torch trigger to start welding. Maintain a consistent arc length and travel speed.
