Control Panel Features

• Digital Display: Shows welding parameters such as wire feed speed, voltage, and current.
• Adjustment Knobs: For fine-tuning welding parameters.
• Automatic/Manual Mode Button: Toggles between pre-set and user-defined settings.
• Material Selection Button: Allows selection of different welding materials (e.g., steel, stainless steel, aluminum).
• Gas Type Selection: For selecting appropriate shielding gas (e.g., CO2, Ar/CO2, Ar).

4. Setup

1. Positioning the Machine: Place the welding inverter on a stable, level surface, ensuring adequate air circulation around the unit.
2. Connecting the Ground Cable: Attach the ground clamp to the workpiece, ensuring a clean, secure electrical connection. Connect the other end of the ground cable to the designated terminal on the front panel of the welding machine.
3. Connecting the Welding Torch: Insert the Kemppi MMG 22 welding torch connector into the corresponding receptacle on the front of the machine. Secure it by tightening the locking mechanism.
4. Installing the Welding Wire Spool: Open the side compartment of the machine (refer to Figure 3.2). Place the appropriate welding wire spool onto the spindle, ensuring it rotates freely. Feed the wire through the guide tube and into the wire feeder mechanism. Close the compartment securely.
5. Connecting the Gas Hose: Connect one end of the gas hose to the gas inlet on the rear of the welding machine and the other end to your shielding gas cylinder regulator. Ensure all connections are tight to prevent gas leaks.
6. Power Connection: Connect the power cord to a suitable single-phase power outlet. Ensure the power supply matches the machine's requirements (230V, 50/60Hz).

5. Operating Instructions

1. Power On: Turn on the main power switch, usually located on the rear or front panel of the machine. The digital display will illuminate.
2. Select Welding Mode:
   • Automatic Mode: Press the "Automatic/Manual" button to select automatic mode. The machine will suggest optimal parameters based on material and wire diameter.
   • Manual Mode: Press the "Automatic/Manual" button to select manual mode. You can then adjust wire feed speed and voltage independently using the control knobs.
3. Select Material and Gas: Use the respective buttons to select the type of material you are welding (e.g., Fe for steel, Al for aluminum) and the appropriate shielding gas (e.g., CO2, Ar/CO2).
4. Adjust Parameters: In manual mode, or to fine-tune in automatic mode, use the adjustment knobs to set the desired wire feed speed and welding voltage. Refer to welding charts for recommended settings for your specific application.
5. Prepare for Welding: Ensure your workpiece is clean and properly grounded. Position the welding torch correctly.
6. Start Welding: Press the torch trigger to initiate the arc and begin welding. Maintain a consistent travel speed and arc length for optimal results.
7. Power Off: After welding, release the torch trigger, then turn off the main power switch. Close the gas cylinder valve.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Kemppi MinarcMig Evo 200.

• Daily:
  • Inspect the welding torch for wear on the contact tip, gas nozzle, and liner. Replace worn parts as necessary.
  • Check all cable connections for tightness and damage.
  • Clean the exterior of the machine with a dry cloth.
• Weekly/Monthly (depending on usage):
  • Clean the wire feeder rollers to prevent wire slippage.
  • Check the gas hose for leaks using a leak detection spray.
  • Inspect the ground clamp for good contact.
• Periodically:
  • Have the machine inspected by a qualified service technician.
  • Clean internal components using compressed air, ensuring power is disconnected.
