*PRO−SET provides PROfessionally de-
veloped SETtings for the weld process.
To use PRO−SET, press the menu button
to display the parameter and adjust the
amperage adjustment control until PRO−
SET flashes on the display. PRO−SET
flashes one time and reveals the profes-
sional setting for the parameter.

TIP: AC Balance controls the cleaning
action. If floating black spots appear in
the puddle, the balance setting is too high.
Turn the balance down until puddle be-
comes clear.

Amperage Control:
Controls the average AC welding
amperage output. Limits the maxim-
um output of a remote amperage
device.
[BAL] Balance Control:* (% EN)
Controls Oxide Cleaning
Increasing setting reduces oxide cleaning. Range is
60 to 80%. (See tips below)
[FREQ]* Frequency Control:
Increasing setting narrows arc width. Range is 70 to
150 Hertz. (See tips below)
[POST] Post Flow Control:
Controls the length of time gas flows after welding
stops. Range is AUTO, OFF − 50T (seconds).
AUTO calculates the time based on the maximum
amperage of each welding cycle. The minimum time
is 8 seconds. Auto = maximum amperage/10.
TIP: AC Frequency controls the width of
the arc cone. For thin fillet welds (less
than 1/4 in.) set the frequency to 120 Hz.
This frequency setting provides a focused
stable arc and produces a narrow weld.
For outside corner or groove welds on
heavy material, a wide weld may be re-
quired. Lower the frequency to between
70 and100 Hz. This frequency setting pro-
duces a wider weld.
