6. Setup
6.1. Power Connection
The MIG-135PLUS supports dual voltage (110V/220V). Ensure the correct power cable is used and connected to a suitable power outlet with proper grounding. The machine automatically detects the input voltage.
6.2. Welding Mode Wiring
Refer to the diagram below for proper connection of welding accessories for each mode.
- MIG Welding (Gasless Flux): Connect the MIG gun to the designated port. Connect the grounding clamp to the negative (-) terminal and secure it to the workpiece.
- MMA Welding (Stick): Connect the MMA gun (electrode holder) to the positive (+) terminal. Connect the grounding clamp to the negative (-) terminal and secure it to the workpiece.
- Lift TIG Welding: Connect the TIG gun to the negative (-) terminal. Connect the gas cylinder to the TIG gun (if using shielding gas). Connect the grounding clamp to the positive (+) terminal and secure it to the workpiece.
6.3. Welding Wire Installation (MIG Mode)
The machine is designed to accommodate a 2lb spool of welding wire.
- Open the wire feed compartment.
- Place the 2lb welding wire spool onto the spindle, ensuring it rotates freely.
- Thread the welding wire through the guide tube and into the drive roller mechanism.
- Close the drive roller tension arm and adjust the tension appropriately for your wire type.
- Feed the wire through the MIG gun liner until it exits the contact tip.
7. Operating Instructions
7.1. Selecting Welding Mode
Use the mode selection knob on the control panel to choose between MIG (Flux), MMA, or Lift TIG welding.
7.2. Control Modes (Automatic vs. Adjustment)
After selecting your welding process, choose your preferred control mode:
- Automatic Mode (SYN): The machine will automatically set optimal voltage and wire feed speed when you adjust the amperage or wire diameter. This is ideal for quick setup and consistent results.
- Adjustment Mode (MAN): This mode allows independent control over current/amperage and voltage, providing greater flexibility for experienced welders to fine-tune their settings.
7.3. 2T/4T Settings (MIG Mode)
The 2T/4T switch on the control panel determines how the MIG gun trigger operates:
- 2T Mode (Two-Touch): Keep pressing the trigger to dispense welding wire and maintain the arc. Release the trigger to stop welding.
- 4T Mode (Four-Touch): Press the trigger once to start dispensing wire and initiate the arc. Release the trigger. The welding continues. Press the trigger again to stop welding. This mode is useful for longer welds to reduce hand fatigue.
7.4. Material Suitability
The MIG-135PLUS is suitable for welding various metal materials:
- Square Pipe
- Metal Cage
- Mild Steel
- Cast Iron
- Galvanized Sheet
- Stainless Steel
7.5. Welding Process (General Steps)
- Prepare Workpiece: Clean the metal surface of any rust, paint, or grease.
- Connect Ground Clamp: Securely attach the ground clamp to the workpiece or welding table.
- Select Mode and Settings: Choose the appropriate welding mode (MIG, MMA, Lift TIG) and adjust parameters (amperage, voltage, wire feed speed) according to the material thickness and type.
- Wear PPE: Always wear a welding helmet, gloves, and protective clothing.
- Start Welding: Initiate the arc according to your chosen mode (2T/4T for MIG). Maintain a consistent travel speed and arc length for optimal results.
- Inspect Weld: After welding, allow the workpiece to cool and inspect the weld for quality.

- Contact Tips and Nozzles: In MIG welding, regularly check and replace worn contact tips and clean or replace clogged gas nozzles.
- Wire Feed System: Keep the wire feed rollers clean and ensure proper tension.
9. Troubleshooting
If you encounter issues, consult this section before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on | No power supply; Faulty power cord/plug; Internal fault | Check power outlet and circuit breaker; Inspect power cord; Contact support if problem persists. |
| No welding arc | Poor ground connection; Incorrect settings; Damaged torch/electrode holder; No wire feed (MIG) | Ensure good ground connection; Verify settings match material; Check torch/holder for damage; Check wire feed system. |
| Poor weld quality (e.g., porosity, weak weld) | Incorrect settings; Contaminated workpiece; Improper technique; Wrong wire/electrode type; Lack of shielding gas (TIG) | Adjust settings; Clean workpiece thoroughly; Improve welding technique; Use correct consumables; Ensure gas flow for TIG. |
| Wire feeding issues (MIG) | Incorrect drive roller tension; Clogged liner; Worn contact tip; Kinked wire | Adjust drive roller tension; Clean or replace liner; Replace contact tip; Ensure wire path is clear. |
| Overheating protection activated | Exceeded duty cycle; Blocked cooling vents; High ambient temperature | Allow machine to cool down; Clear any obstructions from vents; Work in a cooler environment. |
10. User Tips
- For Lift TIG welding, remember that it typically requires an external gas cylinder for shielding gas (e.g., Argon) to achieve clean welds, especially on stainless steel.
- While versatile, this machine is primarily designed for welding iron and steel. Welding aluminum, especially in TIG mode, may require specialized equipment or specific AC TIG capabilities not present in this DC-only Lift TIG function.
- When using the Automatic (SYN) control mode, adjusting the wire diameter or amperage will automatically optimize the voltage and wire feed speed, making it easier to find the right settings for your project.
- Ensure your household wiring can handle the power requirements, especially when operating at higher amperages on 110V.
