Stel REVOLUTION 2500 CE Instruction Manual page 34

Right before you finish the weld, the machine
sends a burst of current that shapes the end of
the wire. Depending on the setting, there might not
be a ball on the end of the wire that needs to be
clipped off before re-striking an arc. The pinch has
the purpose of eliminating the ball that could be
created on the wire at the end of the welding.
Normally this function is in AUTO . This is the
optimal parameter calibrated for every synergic
curve.
Higher is the Pinch value, lower is the possibility
that a ball can be created on the tip of the wire at
the end of the weld.
MIG 4T SPECIAL
This is a Special function for the MIG 4T . This
function allows you to start welding with a welding
parameter higher or lower than the one set.
With the 4T special it is possible to work with three

For example if the main welding parameter is 10
m/min when you press and keep pressed the torch
button the initial welding parameter will be at 12
m/min .
Note: If wire feed speeds selected here are
producing Amperages over 220 amps, the machine
will automatically limit the output accordingly
