Description

Product Description:

  • High-Capacity Power Delivery: Rated for 125 Volts and 50 Amps, this cord is built to handle the substantial power requirements of industrial-grade welding machines and other high-amperage tools, ensuring consistent performance without voltage drop over longer distances.

  • Robust Connector Design: Features a NEMA 7-50P (Plug) and NEMA 7-50R (Receptacle). This specific configuration is less common than standard NEMA 5-15 but is tailored for certain high-power industrial equipment, offering a secure and correct connection.

  • Heavy-Duty Cable Construction: The cord is available in multiple SJTW, SJTO, and SJTOW jacket types. Here's what that means for you:

    • SJT: Stands for "Service Junior Thermoplastic," indicating it's suitable for hard usage and medium mechanical applications-2.

    • SJTW: The 'W' signifies that the jacket is Weather-Resistant, offering protection against moisture, ultraviolet (UV) light, and abrasion-2. This is ideal for both indoor and outdoor use.

    • SJTO / SJTOW: The 'O' indicates an Oil-Resistant jacket-2. The SJTOW variant provides the highest level of protection with combined oil, weather, and UV resistance, making it perfect for harsh environments like auto repair shops or construction sites.

  • Superior Gauge Options for Optimal Performance: The cord comes in different conductor configurations to suit various needs and length requirements:

    • 10/3 Gauge: This configuration features three 10 AWG conductors. A 10 AWG wire is typically rated for lower amperage (e.g., 30A), so ensure this matches your welder's specific current draw, especially over longer distances.

    • 8/2 + 10/1 Gauge: This hybrid configuration uses two thicker 8 AWG conductors for the current-carrying lines and one 10 AWG wire for the ground. The 8 AWG wire is better suited for the full 50 Amp load-3, reducing heat buildup and power loss, making it the safer choice for heavy-duty, continuous operation at maximum capacity.
