1. Pre Gas Timer
Provides selection for gas flow time prior to the arc
starting (0.5-10s).
2. Start Amp
Provides selection for the amount of amperage
required at the start of the weld (10-320A).
3. Up Slope Time
Sets the transition time from Start Amperage to
Welding Amperage (0-15s).
4. Peak Amp
Provides selection for the Maximum Welding
Amperage required during welding (10-320A).
5. Base Amp
Provides selection for the Base Amperage during the
Pulse Welding cycle (5-320A).
6. Down Slope Time
Sets the transition time from Welding Amperage to
Finish Amperage (0-15s).
7. Finish Amp
Provides selection for the amount of amperage
required at the end of the weld (10-320A).
8. Post Gas Timer
Provides selection for continued gas flow time at the
end of the welding after the arc is out (0.5-15s).
9. AC Hertz
Provides selection to adjust the frequency of the AC
square wave in AC TIG mode. Allows adjustment of
frequency of the AC square wave cycle. The number
of times per second (Hz) the arc switches from + to –
polarity (AC) during AC TIG welding (50-200Hz).
10. AC Balance
Provides balance adjustment of the AC wave form in
AC TIG mode. Allows adjustment of the proportion
of polarity from balanced, to more – polarity for
penetrating action or more + for oxide cleaning action
during AC TIG welding (-5 to +5).
11. Tungsten Diameter
Provides selection of the correct tungsten diameter
for the set welding parameters (1.0-4.0mm).
Warning Alert (14) appears if the parameters are
outside the capability of the tungsten diameter.
