Explanation of Functions and Welding Terms
cess and can be used in adverse conditions where TIG cannot. This
unit cannot be used with E6010 however, and E6011 should be sub-
stituted. A short arc length should be used. A dragging motion is
recommended and a higher arc force setting is recommended for all
rods. If difficulty is experienced, when welding open root, consider
E6011. For best results with stick welding, Everlast recommends
E7014 and E7018 for general purpose use and fabrication. Stainless
rods and aluminum rods may also be used.
Up Slope. This function is used with 2T and 4T settings and is not
used with the foot pedal. (If it were used it would cause a delay in the
ramp up ability of the amps). The Up Slope time allows the arc to
uniformly transition from Start Amps to the Welding Amps, by in-
creasing the amperage as you would with a foot pedal. For this unit,
the Up Slope has been fixed.
Wave Form. The waveform is the shape that is created (visible when
viewed on an oscilloscope) by the AC mode, as the arc cycles be-
tween electrode negative and electrode positive polarity. The wave
form created by traditional power companies is considered to be a
sine wave. This sine wave, when viewed on an oscilloscope is very
smooth and regular, and even rounded at the peaks and valleys of
the wave form. With an inverter welder, pre programmed wave forms
can be generated. Although some units from Everlast offer adjusta-
ble wave forms, this unit only has one wave form. This is the Ad-
vanced Square wave. This is the preferred wave form to be used in
most situations. The shoulders are quite square, and an immediate
transition in current occurs between EN (
-
) and EP(+) and provides
the most time on. This wave form offers the most heat and the fast-
est wet in. Arc stability and directability is excellent. However, it is
also the most likely to consume Tungsten more rapidly due to the
extra heat it provides to the weld and the Tungsten. In general
though, this wave form is highly suitable for use in most applications.
Use with Lanthanated Tungsten for best results. Never use Pure
(Green) or Zirconiated (White or Brown) tungsten with this unit.
Welding Amps. This is the main Amperage control. When used in
the context of Pulse, this is the
“
Peak
”
part of the pulse. Without
Pulse, the main welding amps simply controls the Amperage of the
welder.
