H = Hotstart
I = min current
Arc force
The arc force is important in determining how the current changes in response to
a change in the arc length. A lower value gives a calmer arc with less spatter.
Drop welding
Drop welding can be used when welding with stainless electrodes. The function involves
alternately striking and extinguishing the arc in order to achieve better control of the supply
of heat. The electrode needs only to be raised slightly to extinguish the arc.
Welding regulator
Welding regulator is a type of control that produces a more intense, more concentrated and
calmer arc. It recovers more quickly after a spot short-circuit, which reduces the risk of the
electrode becoming stuck.

Hot start
Hot start increases the weld current for an adjustable time at the start of welding,
thus reducing the risk of poor fusion at the beginning of the joint.
Min current
Used to set the minimum current for the remote control.
