POST-GAS time (0,5 ÷ 25 sec)
ATTENTION: During POST-GAS time, the POST-GAS LIGHT
is flashing, the GREEN LIGHT I
5) Keep pressing the SET key for about 1 sec-
ond to leave the weld parameter setting phase
6) TIG weld as desired
NOTE: The display will visualize the current value
used for welding if the GREEN LED I
continuously during welding
NOTE: During TIG pulsed welding (in the fast and
slow EASY PULSE, ON PULSE modes) the
display indicates the measured PEAK CURRENT
I
for 1 second and the measured BASE CUR-

TIG WELDING WITH SPOT-WELD FUNCTION ON
1) Start up the welder by turning the main switch to position I
2) Press the "weld mode" button and set to
SPOT-WELD position
3) Press the SET button until the corresponding
led starts flashing
4) Turn the knob to set to desired SPOT-WELD
TIME (0,5 ÷ 10 sec)
5) Now continue in the same way as for normal TIG welding,
setting the various parameters as indicated in the TIG
WELD procedures
PULSATING TIG WELD
Pulsating TIG welding can be done in 3 ways with MATRIX
250 HF:
• Fast ON-PULSE (only TIG DC)
Pulsating TIG weld with manually set weld parameters;
• Slow ON-PULSE (TIG AC and DC)
Pulsating TIG weld with manually set weld parameters;
• EASY PULSE (only TIG DC)
Pulsating TIG weld with weld parameters set in synergy.
NOTE: Pulsation is automatically cut off while the current is on
INITIAL and FINAL.
1) Start up the welder by turning the main switch to position I
is on.

2A)Press the "pulsation" button until the desired
function is working (the ON PULSE LIGHT is
on)
3A)Set the following pulsation parameters by
pressing the SET button repeatedly:
PEAK CURRENT I
(5 ÷ 250 A)

2B)Press the "pulsation" button until the corre-
sponding led starts flashing
3B)The following weld parameters can be set by
pressing the SET button repeatedly
