Which switch on the FCAW power source can be moved while welding?

Explanation:
None of the switches on the FCAW power source should be moved while the arc is welding. Once the arc is established, changing control settings like the voltage selector, the power on/off, or the arc force can cause a sudden shift in current, arc length, or stabilization. That abrupt change can lead to an unstable arc, excessive spatter, poor bead quality, or even safety hazards. Set the desired parameters before starting, and only adjust between weld passes or after stopping and turning the machine off.
