1. Introduction
The PATON StandardMIG-350-400V is a professional 3-in-1 inverter welding machine designed for MIG/MAG, TIG LIFT, and MMA welding processes. This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your welding unit. Please read this manual thoroughly before operating the device.
2. Safety Instructions
Always prioritize safety when operating welding equipment. Failure to follow these instructions can result in serious injury or death.
- Personal Protective Equipment (PPE): Always wear a welding helmet with appropriate shade, flame-resistant clothing, welding gloves, and safety shoes.
- Ventilation: Ensure adequate ventilation to remove welding fumes and gases from the work area.
- Fire Hazards: Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
- Electrical Safety: Ensure the welding machine is properly grounded. Do not operate in wet conditions. Inspect cables and connections for damage before each use.
- Arc Rays: Welding arcs produce intense visible and invisible (UV and IR) rays that can burn eyes and skin. Protect yourself and bystanders.
- Fumes and Gases: Welding fumes and gases can be hazardous to your health. Avoid breathing them.

4. Setup
Follow these steps to set up your PATON StandardMIG-350-400V welding machine.
4.1 Power Connection
Connect the welding machine to a 400V AC power supply. Ensure the power source meets the machine's requirements as specified in the technical data.
4.2 Ground Clamp Connection
Attach the ground clamp cable to the designated terminal on the welding machine. Securely connect the ground clamp to the workpiece or welding table to ensure a proper electrical circuit.

4.3 Welding Torch and Electrode Holder Connection
- MIG/MAG: Connect the Abicor Binzel MB25 welding torch to the EURO connector on the front panel.
- MMA: Connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal for most electrodes. Reverse polarity if required by the electrode manufacturer.
- TIG LIFT: Connect the TIG torch (not included in standard package) to the appropriate terminal.
4.4 Gas Connection (for MIG/MAG and TIG)
For MIG/MAG and TIG welding, connect the gas hose from your shielding gas cylinder to the gas connector on the rear of the machine. Ensure all connections are tight to prevent gas leaks.

4.5 Wire Feeder Setup (for MIG/MAG)
Open the side panel to access the wire feeder compartment. Install the wire spool (up to 15 kg) onto the spindle. Thread the welding wire through the wire feeder mechanism, ensuring it passes through the correct rollers and liner to the welding torch. The machine features a durable 4-roller feeding system for precise wire delivery.

5. Operating Instructions
The PATON StandardMIG-350-400V offers multiple welding modes and intuitive controls.
5.1 Control Panel Overview
The front panel features a digital display and control knobs for adjusting welding parameters. The display shows voltage, wire feed speed, and program settings.
Image: Close-up of the control panel.
5.2 Mode Selection
Use the 'MODE' button on the control panel to switch between MIG/MAG, MMA, and TIG LIFT welding modes.
5.3 Parameter Adjustment
- Voltage/Current: Use the 'VOLTAGE' knob to adjust welding voltage (MIG/MAG, TIG) or current (MMA).
- Wire Feed Speed: For MIG/MAG, adjust the wire feed speed using the dedicated knob.
- Inductance: The adjustable inductance feature helps stabilize the arc, reduce spatter, and improve weld quality.
- Pulse Welding: This machine supports pulse welding in MIG/MAG, MMA, and TIG modes, offering enhanced control over heat input and improved weld quality, especially for thin materials and non-ferrous metals.
5.4 Program Memory
The unit allows you to save and recall up to 15 preferred welding parameter settings. This feature is ideal for repetitive tasks and ensures consistent results.
5.5 Gasless Welding (FCAW)
The PATON StandardMIG-350-400V supports gasless welding with self-shielding flux-cored wire. This eliminates the need for shielding gas, making it suitable for outdoor use or in windy conditions.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Periodically clean the exterior of the machine and ensure cooling vents are free from dust and debris. Use compressed air to clean internal components if necessary, ensuring the machine is unplugged.
- Cable Inspection: Regularly inspect all welding cables, torches, and ground clamps for cuts, abrasions, or loose connections. Replace damaged components immediately.
- Wire Feeder: Clean the wire feeder rollers and guide tubes to prevent wire feeding issues. Check for wear on the rollers and replace if necessary.
- Gas Connections: Check gas hoses and connections for leaks using a leak detection spray.
7. Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to the machine | Power cable unplugged, circuit breaker tripped, faulty power switch | Check power connection, reset circuit breaker, contact service if switch is faulty |
| No welding arc | Poor ground connection, incorrect welding parameters, damaged torch/electrode holder | Ensure good ground contact, adjust parameters, inspect and replace damaged parts |
| Wire feeding issues (MIG/MAG) | Kinked wire, clogged liner, worn feed rollers, incorrect tension | Check wire path, clean/replace liner, inspect/replace rollers, adjust tension |
| Poor weld quality | Incorrect parameters, insufficient shielding gas, contaminated workpiece, improper technique | Adjust voltage/current/wire speed, check gas flow/supply, clean workpiece, refine welding technique |
| Overheating protection activated | Exceeded duty cycle, blocked cooling vents, high ambient temperature | Allow machine to cool down, ensure clear airflow, operate within duty cycle limits |
