4. Setup Instructions
Before starting any welding operation, ensure the machine is placed on a stable, level surface in a well-ventilated area, away from flammable materials.
4.1 Power Connection
- Connect the welder to a suitable power supply as specified in the technical parameters. Ensure the power outlet is properly grounded.
- Verify the input voltage matches the welder's requirements.
4.2 Welding Wire Installation (MIG/Flux-Cored)
This welder is designed to use 2LB flux-cored 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. The tension should be firm enough to feed the wire without slipping, but not so tight as to deform the wire.
- Feed the wire through the liner of the MIG gun.

- MIG Welding: Connect the MIG gun to the designated port. Connect the grounding clamp to the negative (-) terminal and securely attach it to the workpiece.
- MMA (Stick) Welding: Connect the electrode holder (MMA gun) to the positive (+) terminal and the grounding clamp to the negative (-) terminal.
- Lift TIG Welding: Connect the TIG torch to the negative (-) terminal and the grounding clamp to the positive (+) terminal. If using a gas TIG setup, connect the gas cylinder to the TIG torch.
The welding gun is a split 3M design, allowing for easy installation, disassembly, and maintenance.
5. Operating Instructions
5.1 Selecting Welding Mode
The ANDELI 135A offers four welding modes: SYN MIG, MAN MIG, FLUX MMA, and LIFT TIG. Use the mode selection knob on the control panel to choose the desired process.
Image: Overview of the 4-in-1 welding modes: SYN MIG (Synergic MIG), MAN MIG (Manual MIG), MMA (Stick), and LIFT TIG. Each mode adapts to diverse workflows.
- SYN MIG (Synergic MIG): Automatic matching of current and voltage, ideal for beginners.
- MAN MIG (Manual MIG): Separate regulation of current and voltage, suitable for experienced professionals.
- FLUX MMA (Stick): Uses 1.6/2.0/3.2mm welding rods.
- LIFT TIG: Provides powerful performance for easy TIG welding.
5.2 Adjusting Parameters
Depending on the selected mode, you can adjust welding parameters using the control knobs. The large LED display will show real-time data.
- Automatic Mode (SYN MIG): The machine automatically matches current and voltage based on wire feed speed or material thickness. No manual adjustment is typically required.
- Adjustment Mode (MAN MIG, MMA, LIFT TIG): Current and voltage can be controlled separately and precisely adjusted to suit your specific welding needs and material.
5.3 2T/4T Settings
The 2T/4T function provides different trigger control options for the welding gun.
Image: Explanation of 2T (Hold) and 4T (Open/Close) trigger settings. In 2T mode, you keep pressing the switch to dispense wire and release to stop. In 4T mode, press once to start and once again to stop, allowing for longer welds without continuous trigger pressure.
- 2T Mode (Two-Touch): Keep pressing the welding gun switch to dispense the welding wire and maintain the arc. Release the switch to stop welding. This mode is suitable for short welds.
- 4T Mode (Four-Touch): Press the welding gun switch once to start dispensing wire and initiate the arc. Release the switch, and the arc will continue. Press the switch again to stop welding. This mode is ideal for longer welds, reducing operator fatigue.
5.4 Welding Applications and Material Suitability
The ANDELI 135A is suitable for welding various metal materials and applications.

6. 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 and debris from the internal components, especially the cooling fan and heat sinks. Ensure the machine is unplugged before cleaning.
- Wire Feed System: Inspect the wire feed rollers for wear and tear. Clean any debris from the wire guide and liner. Ensure proper tension is maintained.
- Welding Gun/Torch: Check the nozzle, contact tip, and diffuser for wear. Replace them as needed. For TIG torches, inspect the collet, collet body, and tungsten electrode.
- Cables and Connections: Inspect all welding cables, power cords, and connections for damage, fraying, or loose contacts. Replace damaged parts immediately.
- Storage: Store the welder in a dry, clean environment, protected from dust and moisture.
- Overheating Protection: The machine features an efficient heat dissipation channel to prevent overheating. Ensure the air vents are clear and unobstructed during operation.
