Ground Clamp Connection:
- Connect the ground clamp plug to the "+" socket on the front panel of the welding machine.
- Securely attach the ground clamp to your workpiece, ensuring good electrical contact.
-
Torch/Electrode Holder Connection:
- For MIG welding, connect the MIG gun/torch connector plug to the appropriate socket (usually the large central socket) and the torch control cable to the "-" socket.
- For MMA welding, connect the electrode holder plug to the "-" socket.
- For Lift TIG welding, connect the TIG torch (WP-17V, not included) to the "-" socket.
-
Wire Installation (MIG/Flux Cored):
- Open the wire feed compartment.
- Install the 2 lbs (.030" or .039") welding wire spool onto the spindle.
- Thread the wire through the guide tube and into the drive roller mechanism.
- Ensure the drive roller matches the wire diameter.
- Close the compartment.

Gas Connection (Gas MIG):
- Connect the gas hose to the gas inlet on the back of the machine and to your gas cylinder regulator.
- Ensure all connections are secure and leak-free.
6. Controls and Display
The MT2000II features an intuitive LCD display and control knobs for easy adjustment.
- Digital Display: Shows welding voltage (V) and wire speed/current (A/m/min).
- Multi-function Knob: Adjusts welding voltage or current depending on the selected mode.
- Selection Button: Toggles between welding modes (MMA, CO2/0.8, MIX/0.8, FLUX/0.8, FLUX/1.0, LIFT TIG).
- Wire Speed Knob: Adjusts wire feed speed (for MIG modes).
- Voltage Selection: Indicates AC 110V or AC 220V input.
The Synergic Control feature automatically matches wire feed speed and voltage, simplifying setup for beginners.
7. Operating Modes
The MT2000II supports four welding processes:
7.1. MMA (Manual Metal Arc) / Stick Welding
- Electrode Diameter: 2.5mm, 3.2mm, 4.0mm.
- Applicable Thickness: 2-12mm.
- Features: Super easy to strike an arc, low spatter, stable current, and good performance.
- Setup: Connect electrode holder to "-" socket, ground clamp to "+" socket. Select MMA mode. Adjust current using the multi-function knob.
7.2. MIG (Metal Inert Gas) Welding
The machine supports Gas MIG, Gasless MIG (Flux Cored), and Mixed Gas MIG.
- Wire Diameter: 0.8mm / 1.0mm solid or flux cored wire.
- Applicable Thickness: 1-8mm.
- Setup: Install appropriate wire, connect MIG gun. For Gas MIG, connect gas hose to gas cylinder. Select the desired MIG mode (CO2/0.8, MIX/0.8, FLUX/0.8, FLUX/1.0) using the selection button. Adjust welding voltage and wire speed.
7.3. Lift TIG Welding
- Tungsten Diameter: 1.6mm, 2.4mm.
- Applicable Thickness: 1-6mm.
- Materials: Largely welding stainless steel, sheet iron, carbon steel.
- Note: Requires a WP-17V TIG Torch (not included) to use this function. Connect the TIG torch to the "-" socket. Select LIFT TIG mode. Adjust current.
8. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Regularly clean the machine's exterior with a dry cloth. Use compressed air to blow out dust from the internal components, ensuring the machine is unplugged and completely de-energized.
- Cable Inspection: Inspect all cables (power, ground, torch) for cuts, fraying, or damage before each use. Replace damaged cables immediately.
- Wire Feed Mechanism: Keep the wire feed rollers and liner clean. Remove any metal dust or debris that could impede wire feeding.
- Torch Nozzle/Tips: Clean or replace MIG torch nozzles and contact tips as needed to ensure consistent arc performance.
- Storage: Store the welding machine in a dry, clean environment, away from excessive dust, moisture, and corrosive materials.
9. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to machine | Power cord unplugged, circuit breaker tripped, power switch off. | Check power connections, reset breaker, turn power switch on. |
| No arc | Poor ground connection, incorrect settings, faulty electrode/wire. | Ensure good ground, verify settings, replace consumables. |
| Wire feed issues (MIG) | Incorrect drive roller tension, clogged liner, wrong drive roller size, tangled wire. | Adjust tension, clean liner, check roller size, untangle wire. |
| Overheating protection activated | Exceeded duty cycle, poor ventilation. | Allow machine to cool down, ensure proper airflow around the unit. |
If problems persist, contact customer support.

11. User Tips
- For optimal MIG welding, ensure your gas flow rate is consistent and appropriate for the material and wire type.
- When using flux-cored wire, remember that it produces its own shielding gas, so no external gas cylinder is needed.
- Practice on scrap metal to fine-tune your settings before working on your main project.
- Keep your welding area clean and free of clutter to prevent accidents.
- Always check the polarity settings for your chosen welding process and wire type.
