Fig. 6 shows a selected welding amper age of 100
amps. When you strike an arc, the LCD will change and
show the accrual welding amperage along with the arc
voltage.
In order to access the settings submenu, press button E
( Fig. 4 ). The following submenu will appear ( Fig. 7 ).
The settings submenu ( Fig. 7 ) allows you to select a hot
start percentage for the stick electrodes. By turning right
encoder G ( Fig. 4 ), the hot start per centage can be
changed to the desired setting. In order to adjust the arc
force setting, press button C ( Fig. 4 ); you will see the
little arrow next to the % sign moving from the first line
in the display to the second line in the display. Now,
turning right encoder G will change the arc force value.
(For more information regarding Hot Start and Arc
Force, please refer to the Glossary , which starts on Page
34 .)
In order to start welding, either press the home button
( Fig. 4 , B ) or wait five ( 5 ) seconds for the display to
revert back to the welding screen. Now, strike an arc.
While still in the Arc Settings screen, press button E
( Fig. 4 ) once to access the advanced pulse settings
screen ( Fig. 8 ).
Press button C ( Fig. 4; CHANGE ) to highlight either
OFF or ON, as shown in Fig. 8 . Confirm your changes
by pressing button E ( Fig. 4; the green check mark ).
Turning right encoder G ( Fig. 4 ) will now change the
pulse frequency from 0.4Hz to 5Hz. You may adjust
your pulse frequency according to your application, the
rod you are using, or personal preference.
Press button C ( Fig. 4; SELECT ) to change the Duty-
Cycle, and press button C again to change the Ibase
current. Duty-Cycle refers to pulse-on time or the
percentage of time that you weld at peak current (the
previously adjusted welding current) over the
background current. Ibase current, a percentage of the
peak/welding current, refers to the background current.
All other HTP stick welding machines (the Inverarc 200
TLP and the Invertig 221) have the duty-cycle and the
Ibase current factory fixed at 50% each. After months of
research and years of experience, a 50% setting has
proven to be an all-around good setting for most rods
and most situations. For you, a good start point is to
keep the duty-cycle and Ibase current values at 50% and
adjust from there.
