Section 3
50-75% Pulse Amp setting is typically used to help
with timing the addition of filler metal to the weld
puddle. A higher pulse frequency level combined with
variations in Pulse Time On and a narrow/wider ratio
can be used to prevent burn through and speed up
welding on thin materials. It can also help maintain a
proper bead on a thin edge weld or prevent burn
through on extremely thin metal. A fast pulse speed
will make fine ripples in the weld while a slow pulse
speed will give a much more coarse, but visually ap-
pealing result. There are limitless ways to adjust the
pulse. Keep in mind though, that the basic purpose of
the pulse is to average the heat input while maintain-
ing penetration. Do not attempt to use pulse while in
stick mode.
6. Arc Force Control/Auto Hot Start. When stick weld-
ing, arc force is used to help improve performance of
the welder with certain metals and welding rods. The
arc force boosts and decreases current flow to match
the demands of arc length and position. As arc length
is decreased, voltage tends to drop so extra amps are
introduced to help maintain a steady arc. Hot start
amps boost the starting amperage automatically to
heat up the welding electrode and weld area so the arc
starts cleanly, without sticking or porosity. Both fea-
tures are inactive while welding in TIG mode.

7. Foot Pedal. 47k . Select 2T on the panel. Select
the maximum amp value desired on the panel. The
foot pedal will only control amps up to the range gov-
erned by the main amp control. If more amperage is
needed raise the amp level on the panel. The foot
pedal also controls both Welding Amps, and Pulse
Amps through the ratio established by selecting the
pulse Amp % on the panel. Welding with pulse and the
foot pedal takes practice, as it will seem the welder is
welding at less amps than it is. Always set the panel
amps to about 25% more than what is needed. In-
creasing the amps more than this margin on the panel
will reduce the accuracy of the foot pedal by lowering
the resolution of the foot pedal. Be sure to turn up/
down slope to the minimum settings or the 2T pro-
gramming will be active and interfere with pedal oper-
ation. The pedal cannot override the 2T amp slope
controls. For more accurate and responsive control,
Everlast offers a US made foot pedal available as an
additional option. Do not attempt to control the stick
function with the foot pedal.
8. Air-cooled torch. A water cooler is not necessary
for use with the standard PowerTIG 200DX torch. The
Basic theory and function
units are equipped with a WP 26 air-cooled torch. However
any after market water cooled torch may be used provided
the proper 35 series DINSE style connector is used. Remem-
ber: Using a water-cooled torch even briefly without water
can seriously and permanently damage your torch. Everlast
water cooled torches used without water-coolers cannot be
warrantied unless cleared by Everlast. Everlast carries wa-
ter-coolers designed to cool the maximum amp capacity of
the welder. All consumables should be interchangeable
with other brand torches with similar designations. They
should be available for local purchase. No special consuma-
bles are required. Although a small starter kit of consuma-
bles is included, you will need more consumables fairly
quickly. No Tungsten is included with the starter kit. Actual
starter kit contents may vary. Contact Everlast if you de-
sire to purchase an air cooled torch that is complete, ready
to go.
9. DINSE style connector. Everlast uses a 35-70mm² con-
nector for both negative and positive connectors, which is a
standard connector within the welding industry. This is
commonly known as a 1/2" or 50 series DINSE-style con-
nector. The connector allows the use of almost any brand
or style of TIG torch.
10. 7 pin remote/foot pedal connector. This 7 pin connector
is available from Everlast should it become damaged. See
Pin-out reference found near the end of this manual.
11. Argon quick connect. This is a 9 mm size quick connect
nipple. These are commonly available from Everlast or
online sites which carry torches and fittings. Should you
need a new one for your torch or damage yours, consult
Everlast. Do not use a nipple that is scarred, bent or other-
wise deformed. Damage to the female connector may re-
sult. Serious leaks may occur.
12. Low amp starts. The units have been configured to be
able to start and weld at approximately 5 DC and 20 AC
(±3) amps. However, to obtain the most stable starts, a
slightly higher amp setting may be required, or a smaller
tungsten may be necessary. After the arc is started, amps
may be reduced to a minimum level (with the foot pedal).
This is accomplished by pressing down more on the foot
pedal until the arc stabilizes, then backing the amps down
slowly until the arc stabilizes at the minimum selected
amps.
13. Argon Regulator. The argon regulator is calibrated in
lpm, not in cfh. (subject to change)
