Electromagnetic Compatibility (Emc) - Lincoln Electric INVERTEC Serie Manual De Instrucciones

Welding Mode Switch: With three positions,
controls the welding mode of the machine:
two for Stick welding (Soft and Crisp) and
one for Lift TIG welding.
• Soft Stick: For a welding with a low
spatter presence.
150S
•
170S Crisp Stick: For an aggressive welding,
only with an increased Arc stability.
•
Lift TIG: When the mode switch is in
the Lift TIG position, the stick welding
functions are disabled and the machine
is ready for Lift TIG welding. Lift TIG is
a method of starting a TIG weld by first
pressing the TIG torch electrode on the
work piece in order to create a low
current short circuit. Then, the
electrode is lifted from the work piece to
start the TIG arc.
170S only Meter: The meter displays the preset
welding current before welding and the
actual welding current during welding.

150S / 170S: This machine has a F.A.N. (Fan
As Needed) circuitry inside. The machine
automatically reduces the speed of the fan or
turns it OFF. This feature reduces the amount
of dirt which can be drawn inside the machine
and reduces power consumption. When the
machine is turned ON the fan will turn ON. The
fan will continue to run whenever the machine
is welding. The F.A.N. feature is active after
that the machine doesn't weld for more than 10
minutes, the fan speed will return to the
maximum speed if a welding operation restarts.
