Fine setting (parameter adjustable in the "rFP cycle setup menu)
In pulsed welding, the fine-setting function enables optimising the place of droplet detachment according to the variation in the compositions of utilized
wires and welding gases.
When fine spatter that may adhere to the workpiece is observed in the arc, the fine-tune setting must be changed toward negative values.
If large drops are transferred by the arc, the fine-tune setting must be changed towards positive values.
PR-SPRAY OR WIRE SHARPENING
The end of welding cycles can be modified to prevent the formation of a ball at the end of the wire. This wire operation produces almost
perfect restriking. The selected solution consists in injecting a current peak at end of cycle, which causes the wire end to become pointed.
Note: This current peak at end of cycle is not always desirable. For instance, when welding thin sheet metal, such this mechanism can cause
