Welding process employing variable minimum current |
摘要 |
A constant voltage (CV) welding process power supply including a controller that implements a variable minimum current is provided. The controller is configured to periodically compute a running current value during a welding operation. The controller is also configured to periodically compute a minimum current value based on a difference between the running current value and a preset offset value, wherein the preset offset value remains constant throughout the welding operation. |
