5. Setup
5.1 Power Connection
The welder supports both 110V and 220V input. Ensure the correct power cord is used and the voltage switch (if applicable) is set correctly for your power supply. Always turn off the machine and wait for the fan to stop before switching voltage settings.
5.2 Wire Installation (MIG/Flux Core)
- Open the wire spool compartment.
- Mount the wire spool onto the spindle, ensuring it rotates freely.
- Thread the welding wire through the wire feed mechanism and into the MIG torch liner.
- Close the wire feed roller tension arm and adjust tension appropriately for the wire diameter.
- With the torch pointed away from yourself and others, press the trigger to feed the wire through the torch until it exits the nozzle.
5.3 Gas Connection (for Gas MIG)
For Gas MIG welding, connect a suitable shielding gas cylinder (e.g., Argon/CO2 mix for steel) to the gas inlet on the rear of the machine using a gas hose and regulator. Ensure all connections are secure and leak-free.
5.4 Torch and Ground Clamp Connection
Connect the MIG torch to the appropriate connector on the front panel. Connect the ground clamp cable to the designated terminal and securely attach the clamp to the workpiece, ensuring good electrical contact.

6. Operating Instructions
6.1 Power On and Mode Selection
Turn on the main power switch. Use the control panel to select your desired welding mode (Gas MIG, Flux Core MIG, Lift TIG, or Stick).
6.2 Parameter Adjustment
The large LED display allows for precise control over welding parameters.
- Synergy MIG Mode: For simplified setup, select Synergy MIG. Input the plate thickness and wire diameter, and the machine will automatically suggest optimal voltage and wire feed speed. Fine-tune as needed.
- Manual MIG Mode: Manually adjust current (amperage) and voltage independently to suit your specific welding requirements.
- MMA (Stick) Mode: Adjust parameters such as Hot Start (amps up initial current for easier ignition) and Arc Force (helps prevent electrode sticking and controls the molten puddle).
6.3 2T/4T Function
The 2T/4T function enhances control during MIG welding:
- 2T (Two-Touch): Press and hold the trigger to start welding; release to stop. Ideal for short welds and precise control.
- 4T (Four-Touch): Press and release the trigger to start welding; press and release again to stop. This allows for continuous welding without holding the trigger, reducing operator fatigue during long passes.

7. Welding Modes Overview
7.1 Gas MIG Welding
Gas Metal Arc Welding (GMAW) uses a continuously fed solid wire electrode and an external shielding gas (e.g., Argon/CO2) to protect the weld puddle from atmospheric contamination. This mode is suitable for welding various metals, including stainless steel and carbon steel, producing clean welds with minimal spatter.
7.2 Flux Core MIG Welding
Flux-Cored Arc Welding (FCAW) uses a tubular wire electrode filled with flux, which produces its own shielding gas when burned. This mode is ideal for outdoor welding or on dirty/rusty materials, as it does not require an external gas cylinder. It is commonly used for welding carbon steel.
7.3 Lift TIG Welding
Lift Tungsten Inert Gas (TIG) welding provides precise control and high-quality welds, especially on thinner materials and stainless steel. This mode requires a separate WP-17V TIG torch and an inert shielding gas (typically Argon). The arc is initiated by briefly touching the tungsten electrode to the workpiece and lifting it, minimizing contamination.
7.4 Stick (MMA) Welding
Shielded Metal Arc Welding (SMAW), or Stick welding, uses a consumable electrode coated with flux. This mode is robust and suitable for welding thicker materials, often in outdoor or less-than-ideal conditions. It is effective on various types of steel.
7.5 Recommended Welding Parameters
The following table provides general guidelines for welding parameters. Actual settings may vary based on material type, thickness, joint configuration, and operator skill.

8. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your welder.
- Daily Inspection: Check all cables, connections, and the MIG torch for wear or damage. Ensure the ground clamp makes good contact.
- Cleaning: Keep the machine clean and free of dust and metal particles. Use compressed air to blow out internal components periodically, ensuring the machine is unplugged.
- Wire Feed Mechanism: Inspect the wire feed rollers for wear and ensure they are clean. Replace worn rollers as needed.
- MIG Torch: Regularly clean or replace the contact tip, gas nozzle, and diffuser. Ensure the liner is free of obstructions.
- Cooling Fan: Ensure the cooling fan vents are clear of obstructions to maintain efficient heat dissipation.
9. Troubleshooting
Refer to the following table for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to the machine | Power cord unplugged, circuit breaker tripped, incorrect voltage setting. | Check power connection, reset breaker, verify voltage switch setting. |
| No arc when welding | Poor ground connection, incorrect welding mode, worn contact tip, wire feed issue. | Ensure ground clamp is secure, select correct mode, replace contact tip, check wire feed. |
| Poor weld quality (excessive spatter, porosity) | Incorrect parameters (voltage/wire speed), insufficient shielding gas (Gas MIG), dirty workpiece, incorrect stick electrode. | Adjust parameters, check gas flow/cylinder, clean workpiece, use appropriate electrode. |
| Wire not feeding | Wire tangled, wire feed roller tension incorrect, clogged liner, worn contact tip. | Untangle wire, adjust roller tension, clean/replace liner, replace contact tip. |
| Overheat protection activated | Exceeded duty cycle, blocked cooling vents, high ambient temperature. | Allow machine to cool, clear vents, reduce welding time. |
