The selection button for additional MIG functions can be used to activate the Hot Start, Crater
Fill or WisePenetration (licence required) function. Further presses of the selection button can
select one or more of the above func tions. Only the available additional functions for each
method can be selected.
• HotStart function is meant to reduce initial welding errors when welding highly heat-
conductive materials such as aluminium. Hot Start can be selected when using Synergic
1-MIG welding and when the 4T operating mode is selected. In this case, when the start
switch of the gun is held down, a fixed pre-gas time is displayed after which welding
starts at the level determined by the SETUP mode’s Hot Start parameter, returning to the
normal level when the gun switch is released.
• WisePenetration™ is a welding function for delivering constant welding power
regardless of changes in the stick out length. It is an optional feature, which can be
purchased through Kemppi DataStore.
• Crater Fill is meant to reduce welding defects caused by end cratering. The Crater Fill
function can be selected when using Synergic 1-MIG welding and when the 4T operating
mode is selected. When the gun switch is pressed down in connection with termination
of welding, the welding power drops to the crater-filling level selected previously. The
crater filling function is discontinued by releasing the gun switch.
NOTE! In crater fill, the initial value of the welding power must be greater than the final
value, and therefore the adjustment ranges for the initial and final values are restricted
automatically, if necessary.

Parameters related to these functions are set via the SETUP function (see ’SETUP functions’).
Stopping is performed as with the normal 4T function.
The values of parameters related to additional MIG functions can be changed either with the
SETUP function (see ’SETUP’) or with the Quick SETUP function. Quick SETUP is activated by
simultaneously pressing buttons 1 and 3. In this way, parameters related to MIG additional
functions can be set.
Parameters are selected for adjustment via potentiometer on the left. The value of the
parameter is set via potentiometer on the right. The value is immediately recorded in the
memory.
