IN THIS POSITION, YOU CANNOT CONNECT THE
PEDAL CONTROL ACCESSORY TIG250FP.
N - LED. Pulsed 4-stage TIG welding (auto-
matic).
This program differs from the previous one in that the arc is
both started and shut off by pressing and releasing the torch
trigger or foot switch.
J - LED - THERMAL PROTECTION
Lights when the operator exceeds the duty cycle or percen-
tage intermittence admissible for the machine, and simulta-
neously blocks the current output.
NOTE:
In this condition the fan continues cooling the
power source.
Y - LED
This LED never be lit to ensure safe welding conditions in AC
mode.
A - BALANCE CONTROL
This knob makes it possible to vary the half-
periods of the square wave when working in
TIG AC, welding aluminium.
The point where the two half-waves meet is
zero.
This position will give you less current absorption, reduced
electrode consumption and an ideal ratio between the width
and depth of the bead. If you wish to increase penetration,
turn the knob counter-clockwise; for a cleaner weld with less
penetration, turn the knob clockwise.
THIS FUNCTION IS ENABLED ONLY WHEN TIG WELDING
IS SELECTED IN AC.
