2. Safety Information
Always observe the following safety precautions when using electrical extension cords:
- Inspect Before Use: Before each use, visually inspect the cord for any damage, cuts, fraying, or exposed wires. Do not use if damaged.
- Proper Rating: Ensure the extension cord's voltage and amperage ratings match or exceed the requirements of your welding machine. This cord is rated for 25A, 250V.
- Avoid Overloading: Do not overload the extension cord. Overloading can cause overheating and fire.
- Dry Conditions: Use in dry conditions. While the cord features a water-resistant jacket, avoid submerging it in water or using it in excessively wet environments.
- Secure Connections: Ensure all connections (plug to outlet, cord to welder) are secure and fully inserted to prevent arcing and overheating.
- Keep Away from Heat/Sharp Objects: Do not run the cord near sharp edges, hot surfaces, or moving machinery that could damage the insulation.
- Unplug When Not in Use: Always unplug the extension cord from the power source when not in use or before performing maintenance on your welding equipment.
- Grounding: This cord is designed with a grounding pin. Ensure the power outlet is properly grounded.

4. Setup
- Uncoil the Cord: Fully uncoil the extension cord before use to prevent overheating.
- Connect to Welder: Insert the NEMA 6-50R (female) end of the extension cord firmly into the NEMA 6-50P (male) plug of your welding machine. Ensure a snug fit.
- Connect to Power Source: Insert the NEMA 6-50P (male) end of the extension cord firmly into a compatible 250V NEMA 6-50R wall outlet. Ensure the outlet is properly grounded and rated for the required amperage.
- Route Safely: Route the cord in a manner that avoids tripping hazards, sharp objects, or areas where it could be crushed or damaged.

5. Operating Instructions
Once the extension cord is properly connected to both your welding machine and a suitable power source, you can operate your welding equipment as usual. The cord provides the necessary electrical extension without compromising performance, provided it is used within its rated specifications.
- Ensure the welding machine's power switch is in the OFF position before connecting or disconnecting the extension cord.
- Turn on the power source, then the welding machine.
- Monitor the cord during operation for any signs of overheating (e.g., unusual warmth, melting insulation, smoke). If any such signs appear, immediately disconnect power.
- When finished, turn off the welding machine, then disconnect the extension cord from the power source first, followed by the welding machine.

6. Maintenance
- Cleaning: Keep the cord clean and free from dirt, grease, and debris. Use a dry cloth to wipe down the cord. Do not use harsh chemicals or solvents.
- Storage: When not in use, coil the cord loosely and store it in a dry, cool place away from direct sunlight, extreme temperatures, and potential physical damage. Avoid tight coiling, which can stress the internal wires.
- Regular Inspection: Periodically inspect the entire length of the cord, including the plugs and receptacles, for any signs of wear, damage, or corrosion. Replace the cord if any damage is found.
