OPERATING MANUAL
Functions
The following -/+ perform multiple functions depending
on the operating conditions:
• During programming, these serve to directly
input the desired parameter values.
• During “Run Program” mode, these serve as JOG
switches when no arc is present.
• During welding, they serve as override switches
for each function, within the pre-set limits of the
% override screen.
I. Current: decrease/increase welding current level in
both programming and welding modes.
J. Travel: decrease/increase welding travel (rotation)
speed in both programming and welding modes.
K. Wire: decrease/increase welding wire speed in both
programming and welding modes.
L. Arc Length: decrease/increase welding arc length
(and therefore arc voltage) in both programming
and welding modes.
M. Oscillation Speed: decrease/increase welding
oscillation speed in both programming and
welding modes.
N. Oscillation Amplitude: decrease/increase oscillation
amplitude (torch weave width) during both
programming and welding modes.
O. AGC Stop: primarily used in weld repairs; causes
the AGC operation to cease. While the AGC is
disabled, a warning indicator is displayed on the
LCD. Pressing the button a second time causes the
function to reactivate. When the AGC Stop is on,
the two AGC buttons can be used to jog the torch
up/down.
P. Wire Stop: operation is similar to AGC Stop above,
except that the function interrupted is wire feed.
Pressing this button causes the ller wire feed to
interrupt until pressed for a second time. A warning
indicator is displayed. When the Wire Stop is
actuated, the two wire buttons can be used to jog
wire.
Q. Control knob: increase/decrease any parameter
that has been selected during programming.
During welding, the encoder is used to “steer” the
torch in the seam and adjust the centre point of the
oscillation strokes.
R. USB Port (on top): to connect a standard digital
memory stick. This allows program transfer
between power sources, program archiving, and
QC data downloading. Weld parameters can be
downloaded for subsequent print-out on a PC
equipped with a printer.
1.5 Compatibility
The A7 TIG Orbital System 300 controller is compatible
with A7 TIG Orbital System150 weld heads using an
adapter cable.
