3) TIG 4T welding with direct current (DC-) (4 Step trigger) - the red light
should indicate
The following parameters can be set within given ranges:
•
Is[A] - welding current in amperes adjustable in the range of 5-150A with a
resolution of 1A
•
Ip[%] - initial current adjustable as a percentage of the welding current Is
within the range 5-50% with a resolution of 1%.
• Tn[s] - welding current rise time in seconds adjustable in the range 0.1-5s
with a resolution of 0.1s
• To[s] - welding current fall time in seconds adjustable in the range 0.1-20s
with a resolution of 0.1s
•
Ib[%] - base current adjustable as a percentage of the welding current Is
within the range 10-100% with a resolution of 1%. If the value of the basic
current is set to 100%, the welding current will have a constant value
equal to the set value of Is. If the value of the basic current is different
from 100%, we get pulsating current with the following parameters:
welding current will pulsate with the frequency fp and the duty cycle TH[%]
(see below)
• TH[%] - the duration of current pulses of the value Is as a percentage of
the signal pulse period within the range 1-99%. TH parameter is
adjustable only when the set value of the base current Ib is different
from 100%
•
fp[Hz] - the welding current pulse frequency in Hz, adjustable in the range
0.1-50Hz. fp parameter is adjustable only when the set value of the
base current Ib is different from 100%
•
Ik[%] - final current adjustable as a percentage of the welding current Is
within the range 5-50% with a resolution of 1%.
• Tg[s] - time of gas flow after the arc extinction in seconds, adjustable in
the range 1-25s with the resolution of 1s
You can select the method of ignition using HF button (4):
CONTACT IGNITION - LAMP (8) IS OFF
The welding process is initiated by pressing (and releasing) a control
button on the grip. When the button is pressed the gas valve is opened.
After releasing the button
(while welding don't hold the button
