seconds.
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.
Hot Start
Increases the welding current during a fixed time at the start of the welding process.
Set the value of the hot start current by using the knob. This reduces the risk of
binding defects at the start of the weld.
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.
