Safety Information

Always prioritize safety when operating welding equipment. Failure to follow safety guidelines can result in serious injury or damage to equipment. Ensure you wear appropriate personal protective equipment (PPE), including welding helmet, gloves, and protective clothing. Work in a well-ventilated area to avoid inhaling fumes. Disconnect power before performing any maintenance or adjustments.

Included Components

The PATON ProMIG-350-15-4-400V SF (WAM) welding machine kit typically includes the following items:

• Semi-Automatic Inverter PATON™ ProMIG-350 with 4-roller wire feeder on wheels
• 35 mm² welding cable, 3 meters long, equipped with an ABICOR BINZEL™ earth clamp
• Operating manual (this document)
• Quick release gas connector
• Roller set for 4 diameters of solid wire and 2 diameters of aluminum wire

Setup

Proper setup is crucial for safe and efficient operation. Follow these steps to prepare your welding machine:

1. Placement: Position the welding machine on a stable, level surface in a well-ventilated area, away from flammable materials.
2. Power Connection: Connect the machine to a 400V AC power supply. Ensure the power source meets the machine's requirements.
3. Wire Feeder Connection: Connect the external 4-roller wire feeder unit to the main inverter unit.
4. Ground Clamp Connection: Attach the earth clamp securely to the workpiece or welding table, ensuring good electrical contact.
5. Wire Spool Installation:
   • Open the wire feeder compartment.
   • Mount the appropriate wire spool (5kg, 15kg, or 18kg) onto the spindle.
   • Thread the welding wire through the feeder rollers and into the torch liner. Ensure the correct roller set is installed for your wire diameter (0.6-1.2 mm).
6. Gas Connection (for MIG/MAG): If using shielding gas, connect the gas hose from your gas cylinder (with regulator) to the quick-release gas connector on the machine. Ensure all connections are tight to prevent leaks. For gasless welding, this step is not required.
7. Torch Connection: Connect your welding torch to the EURO connector on the front panel of the machine.

Operating Instructions

The ProMIG-350 offers multiple welding modes. Familiarize yourself with the control panel and settings before beginning any welding task.

General Operation Steps:

1. Power On: Turn on the main power switch. The display will illuminate.
2. Select Welding Mode: Use the mode selection button or knob to choose between MIG/MAG, MMA (Stick), or TIG DC welding.
3. Adjust Parameters:
   • MIG/MAG: Set welding current (Amps), voltage (Volts), and wire feed speed (m/min). Adjust inductance for arc stability and bead shape. Consider using pulse mode for better control on thin materials or specific alloys.
   • MMA: Select electrode type and set welding current (Amps).
   • TIG DC: Set welding current (Amps). If available, adjust pulse frequency and balance for TIG welding.
4. Test Gas (MIG/MAG): If using shielding gas, use the "Test Gas" function to purge the gas line and ensure proper flow.
5. Wire Feed Test (MIG/MAG): Use the "Wire Feed" button to advance the wire through the torch without striking an arc.
6. Begin Welding: Once all parameters are set and safety precautions are observed, you can begin your welding task.

Specific Instructions for Use:

• Gasless Welding: For gasless MIG welding, ensure you are using self-shielded flux-cored wire and select the appropriate polarity on the machine (if adjustable). No shielding gas connection is required.
• Welding Steel: The machine is optimized for welding various types of steel, including mild steel, stainless steel, and acid-resistant steel. Adjust parameters according to the material thickness and type.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine. Always disconnect the machine from the power supply before performing any maintenance.

• Cleaning: Periodically clean the exterior of the machine with a dry, soft cloth. Use compressed air to blow out dust and debris from inside the machine, especially from cooling vents, to prevent overheating.
• Wire Feeder: Inspect the wire feeder rollers for wear and cleanliness. Clean any wire residue or dust from the wire guide and liner. Replace worn rollers as needed.
• Torch and Cables: Check welding cables, torch, and ground clamp for damage, cuts, or loose connections. Replace any damaged components immediately. Ensure the torch liner is clean and free of obstructions.
• Gas Connections: If using gas, check gas hoses and connections for leaks regularly.

Troubleshooting

If you encounter issues with your PATON ProMIG-350, refer to the following common troubleshooting steps:

• No Power:
  • Check the main power switch and ensure it is in the "ON" position.
  • Verify the power cord is securely plugged into a 400V outlet.
  • Check the circuit breaker or fuse for the power supply.
• No Arc:
  • Ensure the ground clamp is securely attached to the workpiece and has good electrical contact.
  • Check all welding cable connections.
  • Verify the welding mode and parameters are correctly set.
  • For MIG/MAG, ensure wire is feeding correctly and the contact tip is not clogged.
• Poor Weld Quality:
  • Adjust welding current, voltage, and wire feed speed according to the material and wire type.
  • For MIG/MAG, check gas flow (if applicable) and ensure the correct shielding gas is used.
  • Ensure the workpiece is clean and free of rust, paint, or contaminants.
  • Check for proper torch angle and travel speed.
• Wire Feeding Issues (MIG/MAG):
  • Check for tangled wire spool.
  • Ensure the wire feeder rollers are clean and correctly tensioned.
  • Inspect the torch liner for blockages or damage.
  • Verify the correct roller set is installed for the wire diameter.
