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.
