Safety Information
Welding can be dangerous. Always follow safety precautions to prevent injury or damage.
- Electric Shock Can Kill: Ensure proper grounding. Do not touch live electrical parts. Wear dry insulating gloves.
- Fumes and Gases Can Be Dangerous: Keep your head out of the fumes. Use ventilation or exhaust to remove fumes from the breathing zone.
- Arc Rays Can Burn Eyes and Skin: Wear a welding helmet with a proper shade filter. Wear appropriate eye protection with side shields. Wear protective clothing made from durable, flame-resistant material.
- Fire and Explosion Hazard: Remove all flammable materials from the welding area. Have a fire extinguisher readily available.
- Hot Parts Can Cause Severe Burns: Allow welded materials to cool before handling. Wear heat-resistant gloves.
- Read the Entire Manual: Before operating the machine, thoroughly read and understand all instructions and safety warnings.

Setup
1. Unpacking and Inspection:
- Carefully remove all components from the packaging.
- Verify that all accessories are present as listed in the product description.
- Inspect the machine for any signs of shipping damage. Do not operate if damaged.
Figure 5: Included accessories typically consist of the welding machine, MIG torch, ground clamp, electrode holder, and flux core welding wire.
2. Power Connection:
- Ensure the power switch on the machine is in the "OFF" position.
- Connect the power cord to a suitable 110V/60Hz power outlet. Ensure the circuit can handle the machine's current draw.
3. Installing Flux Core Wire (for MIG Welding):
- Open the wire feeder compartment.
- Place the 2LBS 0.035" flux core wire spool onto the spindle, ensuring it rotates freely.
- Feed the wire through the guide tube and into the drive rollers.
- Close the drive roller tension arm and adjust the tension appropriately (not too tight, not too loose).
- With the MIG torch straight, press the trigger to feed the wire through the liner and out of the contact tip.

Operating Instructions
1. Selecting Welding Mode:
- Turn on the machine.
- Use the "CHOOSE" button on the control panel to cycle through the welding modes: Flux Core MIG (.030" or .035"), Lift TIG, and MMA.
2. Synergic (SYN) Control:
- When in a MIG mode, the SYN control automatically sets optimal current and voltage based on the selected wire diameter.
- Press and hold the "CHOOSE" button for 3 seconds to activate or deactivate SYN mode. When active, the "SYN" indicator will light up.
- In SYN mode, you primarily adjust the wire feed speed, and the machine will automatically adjust voltage.
Figure 7: Synergic control automatically adjusts voltage and wire feeding speed for stable arc performance. Press and hold 'CHOOSE' for 3 seconds to toggle.
3. Flux Core MIG Welding:
- Select Flux Core MIG mode (.030" or .035").
- Connect the ground clamp to the workpiece.
- Adjust the current/wire speed knob. Use SYN control for automatic settings or manual adjustment.
- Position the MIG torch and begin welding.
- The included AZZUNO AWS E71T-GS .035" Flux Core welding wire is designed for smooth feeding and low splatter.
Figure 8: Specifications for the included Flux Core Welding Wire: Model E71T-GS, Wire Diameter .035", Net Weight 2LBS, Polarity DCEN.
4. Lift TIG Welding:
- Select Lift TIG mode.
- Connect a compatible WP-17V TIG gun (10-25mm²) to the machine (TIG gun not included).
- Connect the ground clamp to the workpiece.
- Adjust the current.
- Touch the tungsten electrode to the workpiece to initiate the arc, then lift slightly to maintain it.
5. MMA (Stick) Welding:
- Select MMA mode.
- Connect the electrode holder to the machine and insert an E6013 electrode.
- Connect the ground clamp to the workpiece.
- Adjust the current.
- Strike the electrode against the workpiece to initiate the arc and begin welding.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Clean Regularly: Use compressed air to blow out dust and debris from the machine's vents and internal components. Do this periodically, especially in dusty environments.
- Inspect Cables and Connections: Check all welding cables, power cords, and connections for wear, cuts, or loose fittings before each use. Replace damaged parts immediately.
- Check Wire Feeder: Ensure the wire drive rollers are clean and free of debris. Verify proper tension for smooth wire feeding.
- MIG Torch Maintenance: Regularly clean or replace the contact tip, gas nozzle (if applicable), and diffuser. Ensure the liner is free of kinks and blockages.
- Storage: Store the machine in a clean, dry place, away from moisture and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power switch off, power cord disconnected, circuit breaker tripped. | Turn on switch, check connections, reset breaker. |
| No arc | Poor ground connection, wrong welding mode, contact tip clogged (MIG), electrode not touching workpiece. | Ensure good ground, select correct mode, clean/replace tip, ensure proper contact. |
| Wire feeding issues (MIG) | Incorrect drive roller tension, clogged liner, wrong size contact tip, wire spool tangled. | Adjust tension, clean liner, use correct tip, untangle wire. |
| Overheat indicator on | Machine has exceeded duty cycle, poor ventilation. | Allow machine to cool down, ensure proper airflow around vents. |
