2. Setup and Installation
Before beginning installation, ensure your welding machine is powered off and disconnected from the main power supply.
- Connect the Quick Connector: Insert the quick connector of the MIG welding gun cable into the corresponding receptacle on your AZZUNO MIG-155F or MIG-155L welding machine. Ensure it is securely fastened.
- Connect the 2-Pin Plug: Attach the 2-pin control plug from the welding gun to the designated control port on the welding machine. This connection enables trigger functionality.
- Connect the Gas Hose: Securely connect the gas hose from the welding gun to the gas outlet on your welding machine. Ensure all connections are leak-free to maintain proper gas shielding.
- Install Consumables:
- Unscrew the gas nozzle from the torch head.
- Screw in the appropriate contact tip for your welding wire diameter.
- Re-attach the gas nozzle, ensuring it is finger-tight.

3. Operating Instructions
Always wear appropriate personal protective equipment (PPE) including a welding helmet, gloves, and protective clothing before operating any welding equipment.
- Power On: Once all connections are secure, power on your AZZUNO welding machine.
- Set Welding Parameters: Adjust the voltage, wire feed speed, and gas flow rate on your welding machine according to the material thickness and type of welding wire being used. Refer to your welding machine's manual for specific parameter guidelines.
- Initiate Arc: Position the welding gun over the workpiece. Press the trigger on the ergonomic handle to initiate the wire feed and arc.
- Maintain Arc: Guide the welding gun along the joint, maintaining a consistent travel speed and arc length for optimal weld quality.
- Release Trigger: Release the trigger to stop the wire feed and extinguish the arc.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your MIG welding gun.
- Nozzle Cleaning: Periodically clean spatter from the gas nozzle. Excessive spatter can obstruct gas flow and affect weld quality.
- Contact Tip Inspection: Inspect the contact tip for wear or enlargement of the bore. Replace worn tips to ensure proper electrical contact and consistent wire feeding.
- Diffuser Cleaning: Clean or replace the gas diffuser if it becomes clogged with spatter or debris.
- Cable Inspection: Regularly check the welding cable and gas hose for any signs of damage, cuts, or kinks. Damaged cables can compromise safety and performance.
- Storage: Store the welding gun in a clean, dry environment when not in use to prevent damage and corrosion.
5. Troubleshooting
This section addresses common issues you might encounter during operation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent Wire Feed | Worn contact tip, incorrect wire tension, clogged liner, wrong drive roll size. | Replace contact tip, adjust wire tension, clean or replace liner, ensure correct drive rolls are installed. |
| Excessive Spatter | Incorrect voltage/wire speed, insufficient gas flow, dirty workpiece, worn contact tip. | Adjust welding parameters, check gas supply and flow rate, clean workpiece, replace contact tip. |
| No Arc | Poor ground connection, power supply issue, trigger malfunction, no wire feed. | Check ground clamp, verify power to welder, inspect trigger connection, ensure wire is feeding. |
| Gas Leakage | Loose gas hose connection, damaged hose. | Tighten all gas connections, inspect hose for damage and replace if necessary. |
