2. Safety Information
Always prioritize safety when operating welding and cutting equipment. Failure to follow safety precautions can result in serious injury or death.
- Personal Protective Equipment (PPE): Always wear a welding helmet with appropriate shade, flame-resistant gloves, protective clothing, and safety shoes. Eye protection is crucial.
- Ventilation: Ensure adequate ventilation in the work area to avoid inhaling welding fumes, which can be hazardous.
- Electrical Safety: Never operate the machine in wet conditions. Ensure the power supply is correctly grounded. Disconnect power before performing any maintenance, changing accessories, or when the machine is not in use.
- Fire Prevention: Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
- Arc Rays: Welding arcs produce intense visible and invisible (UV and IR) rays that can burn eyes and skin. Protect yourself and bystanders.
- Hot Surfaces: The machine and workpieces will become hot during operation. Allow them to cool before handling.
- Gas Cylinders: If using shielding gas, secure gas cylinders properly and handle them with care.
Refer to local safety regulations and standards for additional guidelines.

4. Setup
Proper setup is crucial for safe and effective operation. Follow these steps for connecting your welding torch and accessories.
4.1 Power Connection
- Ensure the machine is switched off before connecting to power.
- Connect the power cord to a suitable 110V or 220V AC outlet, ensuring it matches the machine's voltage setting.
- Verify the power outlet is properly grounded.
4.2 Torch and Accessory Connection
The connection method varies depending on the welding or cutting process. Refer to the diagrams below for correct setup.
Image 4.1: Detailed connection diagrams for various welding and cutting modes.
- MMA (Stick Welding): Connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal.
- Lift TIG Welding: Connect the TIG torch to the negative (-) terminal and the ground clamp to the positive (+) terminal. Connect the gas hose from the TIG torch to the gas regulator on the shielding gas cylinder.
- CUT (Plasma Cutting): Connect the plasma torch to the designated cutting output and the ground clamp to the workpiece. Ensure compressed air is connected to the machine.
- MIG/MAG Welding: Connect the MIG torch to the Euro connector. Connect the ground clamp to the workpiece. For Gas MIG, connect the gas hose from the torch to the gas regulator on the shielding gas cylinder.
- Flux MIG Welding: Similar to MIG/MAG, but no external shielding gas is required as the flux-cored wire produces its own shielding.
5. Operating Instructions
This section outlines the general operating procedures for the MCT-416 welder.
5.1 Control Panel Overview

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ANDELI MCT-416 welder.
- Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup, which can hinder cooling. Use dry, compressed air for internal cleaning if necessary, ensuring the machine is unplugged.
- Consumables: Regularly inspect and replace worn-out consumables such as MIG contact tips, nozzles, TIG collets, electrodes, and plasma cutting electrodes/nozzles.
- Cables and Connections: Check all welding cables, power cords, and gas hoses for cuts, abrasions, or loose connections. Repair or replace damaged components immediately.
- Wire Feeder: For MIG welding, inspect the wire feed rollers for wear and ensure they are clean and properly tensioned.
- Storage: Store the machine in a dry, clean environment when not in use.
7. Troubleshooting
This section provides solutions to common issues you might encounter. For problems not listed here, contact customer support.
