The Higher the Duty Cycle the BetterFor contractors, businesses, and industries where time is money, having a low duty cycle is extremely costly. If you were to use the previous example, where the duty cycle was 30%, that would mean in a one hour period of time the welder would be able to perform the operation for only 18 out of a total of 60 minutes. That is a significant amount of waste in terms of time. As much as 42 minutes of the welder’s time would be spent doing nothing or working on something outside the scope of this particular project. Many welders are making a significant amount of money, so to have them working 30% of the time on a project is a complete waste of any company or business’ resources.
It’s in the MathIt is important to understand that there is a significant difference between using a welder 100% of the time and him or her being available for that duration. It is clear that no welder is going to be able to continuously work on a project for eight straight hours. Even if the duty cycle is at 100%, they are going to need brakes to ensure that they are maintaining their skills and integrity during the well. In addition, there are both state and federal laws which demand a certain amount of rest or a certain number of breaks for those working in these types of industries. They understand that employees need maybe as much as 15 minutes every hour or other hour to give them an opportunity to relax and unwind. In this case, it is clear that some portion of their work time is being lost. However, this makes sense. You want employees who are at their best, and working for three or four straight hours without a break can lead to a weld that has lost its integrity. This is understood by virtually everyone within the industry. However, when a welder is unable to perform their task because the machinery does not allow them to do so or limits their ability to do the work, this is when a waste can occur.
Effects on Duty CycleWhile the welder is looking for the highest possible duty cycle, it is important to understand that the output current has a direct impact on this value. The higher the output current, the greater the decrease in this duty cycle. For example. Welders would be able to attain a 100% duty cycle on output currents of 370 A, but that value will decrease to 60% when the amperage reaches 500 A. The reason behind this is that when large amperages of current are produced, it can lead to extensive overheating of the welding tools. As this begins to warm, a breakdown can occur and this is why it becomes necessary to give time off for cooling to occur.
Does the Duty Cycle of Portable Arc Welders Affect Their Performance?
When it comes to evaluating the performance of best portable arc welders, the duty cycle plays a crucial role. The duty cycle represents the amount of time a welder can operate before it needs to cool down. A higher duty cycle ensures longer working periods, increasing productivity. Thus, the duty cycle directly impacts the performance and efficiency of portable arc welders.
