2. Safety Information
WARNING: Welding operations can be dangerous and may cause injury or death. Always follow safety precautions to prevent electric shock, fire, explosions, burns, and other hazards.
- Electric Shock: Ensure the welding machine is properly grounded. Do not touch live electrical parts. Wear dry welding gloves and protective clothing.
- Fumes and Gases: Keep your head out of the fumes. Use adequate ventilation or exhaust at the arc to keep fumes and gases away from the breathing zone.
- Arc Rays: Wear a welding helmet with a proper shade filter to protect your eyes and face from arc rays. Wear protective clothing to protect skin.
- Fire and Explosion: Remove all flammable materials from the welding area. Have a fire extinguisher readily available. Do not weld on containers that have held combustibles.
- Burns: Hot metal and electrodes can cause severe burns. Wear protective gloves and clothing.
- Maintenance: Disconnect power from the welding machine before performing any maintenance or changing parts on the torch.
3. Product Components
The Telwin BRENNER MT15 welding torch consists of several key components:
- Torch Body/Handle: Ergonomically designed for comfortable grip and control during welding.
- Trigger: Activates the welding process (wire feed and gas flow).
- Gooseneck/Neck: Connects the torch body to the nozzle assembly.
- Nozzle: Directs the shielding gas to the weld pool.
- Contact Tip: Electrically connects to the welding wire and transfers current to it. Must match wire diameter.
- Gas Diffuser: Distributes shielding gas evenly around the contact tip.
- Welding Cable: Carries welding current, shielding gas, and control signals from the welding machine to the torch.
- Euro Connection: Standardized connector for quick and secure attachment to compatible welding machines.

4. Setup and Installation
Follow these steps to properly set up your Telwin BRENNER MT15 welding torch:
- Disconnect Power: Ensure the welding machine is turned off and disconnected from the power supply before connecting the torch.
- Connect Torch to Welding Machine: The MT15 torch features a Euro connection. Align the Euro connector of the torch with the corresponding receptacle on your MIG-MAG welding machine. Push firmly and twist the locking nut clockwise until it is securely tightened.

- Install Consumables:
- Contact Tip: Select a contact tip that matches the diameter of your welding wire (e.g., 0.6mm, 0.8mm, 1.0mm). Screw it firmly into the gas diffuser.
- Gas Diffuser: Ensure the gas diffuser is clean and securely seated.
- Nozzle: Slide the nozzle over the gas diffuser and twist or push to secure it, depending on the nozzle type.
- Load Welding Wire: Follow your welding machine's instructions for loading the welding wire through the wire feeder and into the torch liner. Ensure the wire diameter matches the drive rollers and contact tip.
- Connect Shielding Gas: Connect the gas hose from your welding machine to the gas regulator on your shielding gas cylinder. Ensure all connections are tight to prevent leaks.
- Power On: Once all connections are secure, you may connect the welding machine to the power supply and turn it on.
The Telwin MT15 torch is compatible with Telwin Telmig 195/2, 200/2, 203/2, 250/2 TURBO, Maxima 200, Maxima 230, Technomig 180 Euro, Technomig 210 Synergic, Mastermig 220/2, Technomig 215 Dual Synergic, Electromig 220 Synergic, Technomig 223 Treo, and Technomig 243 Wave machines. It can also be used with other welding machine brands that feature a Euro connection.
5. Operating Instructions
Before operating, ensure all safety precautions are observed and the welding machine settings (voltage, wire speed, gas flow) are appropriate for your material and wire type.
- Prepare Workpiece: Clean the workpiece thoroughly to remove rust, paint, oil, or other contaminants.
- Ground Clamp: Attach the ground clamp securely to the workpiece or welding table, ensuring good electrical contact.
- Position Torch: Hold the torch comfortably with the nozzle positioned at the starting point of your weld. Maintain the correct stick-out (distance from contact tip to workpiece).
- Initiate Arc: Press the trigger on the torch handle. This will initiate gas flow and wire feed, striking an arc.
- Weld: Move the torch steadily along the joint, maintaining a consistent travel speed and arc length. Observe the weld pool and adjust your technique as needed.
- Terminate Weld: Release the trigger to stop the wire feed and gas flow. Allow the weld to cool before handling.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding torch. Always disconnect power from the welding machine before performing maintenance.
- Clean Nozzle: Periodically clean spatter from inside and outside the nozzle. Replace if it becomes excessively worn or damaged.
- Inspect Contact Tip: Check the contact tip for wear, enlargement of the bore, or spatter build-up. Replace if worn, as this can lead to poor arc stability and wire feeding issues.
- Clean Gas Diffuser: Ensure the gas diffuser is free of spatter and debris to maintain proper gas flow.
- Check Liner: If wire feeding problems occur, the wire liner may be clogged or kinked. Consult your welding machine manual for liner inspection and replacement procedures.
- Inspect Cable: Regularly check the welding cable for cuts, abrasions, or damage to the insulation. Damaged cables can pose an electrical hazard and affect performance.
- Euro Connection: Ensure the Euro connection remains clean and free of debris to maintain good electrical contact and gas flow.
7. Troubleshooting
This section addresses common issues you might encounter with your welding torch.
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor Arc Stability / Erratic Arc | Worn contact tip, incorrect contact tip size, poor ground connection, contaminated workpiece. | Replace contact tip, ensure correct tip size, clean and secure ground clamp, clean workpiece. |
| Wire Feeding Problems (Sticking, Jamming) | Clogged or kinked liner, incorrect drive roller tension, worn contact tip, incorrect wire spool tension. | Inspect/replace liner, adjust drive roller tension, replace contact tip, adjust wire spool tension. |
| Excessive Spatter | Incorrect voltage/wire speed, insufficient shielding gas, dirty workpiece, incorrect stick-out. | Adjust welding parameters, check gas flow/supply, clean workpiece, adjust stick-out. |
| No Gas Flow | Empty gas cylinder, closed valve, kinked gas hose, clogged gas diffuser, faulty solenoid valve in welder. | Check cylinder/valve, inspect hose, clean gas diffuser, consult welder manual for solenoid. |
| Torch Overheating | Exceeding duty cycle, insufficient air cooling, damaged cable. | Allow torch to cool, ensure proper ventilation around cable, inspect cable for damage. |
