The inert shielding gas will automatically turn on (‘flow’), when the
program is started by pressing the [START/STOP] button.
The two green buttons [éJOG] and [êJOG], are used to jog the rotor either
prior to starting the program for setup, or after running the program.
To jog the rotor in the normal welding direction (clockwise direction),
press [éJOG]. To jog the rotor in the opposite direction, press [êJOG].
Either button will jog the rotor in their respective directions, at a speed
of 5 rpm.
3.3 Acceptance Buttons
The five buttons at the bottom of the HHC keypad are primarily used to affirm,
negate, select and accept data that has been entered.
The [CLEAR] button in blue is used to remove an entered value, which has
not yet been accepted. Once a value has been entered, but not ‘accepted’
at the active highlighted field, the operator may ‘clear’ the entry simply by
pressing [CLEAR]. In the welding and testing mode, pressing the [CLEAR]
button will zero all the Scale factors applied to the procedure, so the
procedure runs as programmed.
The [ESCAPE] button in blue has primarily the same functions the [Esc]
button has on a standard PC keyboard. As described above, while at the
weld screen, in the editing/modifying mode or, at any other screen, pressing
this key will return to the MAIN MENU.
Both the [YES] and [NO] buttons which are blue, are used to confirm and
accept, or decline and negate any values in the highlighted field. They will
also answer questions prompted on the screen during the program.
The [ENTER] button in green, is used similarly as the [YES] and [NO]
buttons. This button will accept any values entered and those, which are
defaulted. When answering questions, this button will perform the same
functions as [NO], thus declining to change what the questions ask to
change.
3.4 Scaling Buttons
During the welding and testing mode, the operator may scale both the current
and rotor speed values as the procedure allows. This can be accomplished
with the four buttons described below.
The two red buttons labeled [é%CURRENT] and [ê%CURRENT], when
pressed, will increase or decrease the amperage value, before or during the
welding and testing, by one percent (1%) of the current level value.
For example: If the amperage value for the current level is 50 amps, and
the [é%CURRENT] is pressed five times to increase the amperage five
percent (5%), then the actual current value at the arc will be:
50 + 5%(50) = 52.5 amps
50 + 2.5 = 52.5 amps
The two green buttons labeled [é%MOTOR] and [ê%MOTOR], when
pressed, will increase or decrease the rotor speed value, before or during
the welding and testing, by one percent (1%) of the current level value.
For example: If the rotor speed value for the current level is 5 rpm,
and the [ê%MOTOR] is pressed five times to decrease the rotor speed
five percent (5%), then the actual rotor speed value at the tube surface
will be:
5 - 5%(5) = 4.75 rpm
5 - 0.25 =4.75 rpm
If any these buttons are held down continuously, the percentage value
will climb, or fall, as long as the button is held. Each procedure has a
