ESAB PAD 3 is a pulsed arc device which allows for precise control over welding parameters, resulting in smoother and more uniform material transfer. By adjusting pulse frequency, voltage, wire feed speed, and heat input rate, users can achieve optimal welding results for a variety of materials, including aluminum, stainless steel, and non-alloyed steel. The device's six preprogrammed combinations of parameters, combined with the option for manual setting, provide versatility and ease of use.
