The CONTACT-255 inverter welder is a professional welding machine with a maximum power of 220 amps and a duty cycle of 50%. The 50% duty cycle is the percentage of time that the equipment can work at maximum performance with an ambient temperature of 40º in 10-minute intervals. In addition, this welder operates with a no-load voltage of 70V, which refers to the voltage that the machine uses when it is not in the welding process. This data is relevant because it indicates the equipment’s ability to weld with different types of electrodes. Inverter technology is known for its energy efficiency and ability to provide a more stable welding current, making it ideal for a variety of welding applications, including stick arc welding (SMAW) and TIG (GTAW).
