What is Duty Cycle in Welding

The duty cycle is the percentage of time a welding machine can be used continuously. Most SMA welding machines cannot be used 100% of the time because they produce some internal heat at the same time that they produce the welding current. SMA welders are rarely used every minute for long periods of time. The welder must take time to change electrodes, change positions, or change parts. The duty cycle of a welding machine increases as the amperage is reduced and decreases as the amperage are raised. Most SMA welding machines weld at a 60% rate or less. Therefore, most … Continue reading What is Duty Cycle in Welding
