With a 250 Amp rating at 80% duty cycle<\/strong>, this gun is built to handle rigorous industrial fabrication tasks without overheating. The 12-foot cable<\/strong> offers a practical balance of reach and manageability, making it ideal for bench work and medium-sized assembly stations.<\/p>\n This specific model (SKU: 1023-1101) comes equipped with a standard Tweco backend connection<\/strong>, ensuring seamless compatibility with a wide range of wire feeders and power sources that utilize the Tweco style termination. It is pre-configured to run 0.035″ to 0.045″ (0.9mm – 1.2mm) welding wire<\/strong>, covering the most common wire sizes used in general steel fabrication.
