3. Spool Gun Selection. When using the optional
spool gun, the wire speed control is controlled on
the spool gun. You must purchase a MTS ver-
sion of the spool gun to operate correctly. You
may purchase a compatible spool gun directly
from Everlast for your unit. For the best match-
up, we recommend the Parker DSP-360.
4. Flux-Core Operation. Flux-Core welding requires
the use of serrated drive rollers. These grip the
wire and feed it correctly at a steady speed. Flux-
Core drive rolls are available for purchase as an
optional item. Full time use of Flux-Core ller
wire will require the purchase of a flux-core spe-
cic gun. Everlast does not supply this type of
gun, but many after-market Gun suppliers can
supply a Flux -core gun with a Euro-connect t-
ting and will work. Part-time or occasional Flux-
core use with the standard MIG gun is acceptable
as long as the nozzle is kept free of spatter.
5. Generator Use. When running this unit on a gen-
erator, the manufacturer of the generator must
certify it as a having “ Clean Power” output. This
means the unit produces a truer sine wave and is
not a modied sine wave generator and is largely
free from harmonic distortion. A clean power
generator is usually listed as such, but the manu-
facturer of the generator should be able to clarify
the clean power status of the generator through
the technical department of the generator manu-
facturer. Everlast does not keep a list of ap-
proved generators nor does it make endorse-
ments of generators that are listed as clean power
output. The generator power requirement for this
unit is unit is a surge capacity of 12,000 watts.
6. MIG/TIG 2T/4T settings for the sequencer. For
TIG, the 2T/4T feature allows operation without a
foot pedal. In many circumstances, a foot pedal
is not practical for use. So, the 2T/4T function
has been created to allow sequencer program-
ming of the welder to simulate the activities of the
foot pedal while providing more accurate control.
In TIG mode you are controlling Pre-Flow, Post-
Flow, Start/End Amps, Up and Downslope of the
Amps with the sequencer. For MIG, the 2T/4T
feature allows control of the sequencer program-
ming giving the user the choice of operation
styles. This allows the unit to be operated with-
out keeping the trigger pressed. This allows the
user to improve productivity while reducing fa-
tigue. In some circumstances, it allows the unit to
be used with some auto-welding machines.
When used in MIG mode, you are controlling the
Pre-flow, Post-Flow, Start/End WFS, Up and
downslope of the Volts with the sequencer. The
“T” refers to the number of “travels” of the remote
switch required to operate the programming of
the sequencer. 2T is essentially a “press and
hold” operation and all programming is cycled
automatically. Releasing the switch begins the
nal stage of programming. 4T operates differ-
ently in the fact that each touch activates a differ-
ent stage of the programming, allowing for great-
er control. In 4T mode, while welding at full se-
lected value (MIG: WFS, TIG: Amps), no nger
contact with the switch is required. Following the
graphic lines below, you can visually trace the
activity and function of each part of the welding
cycle. In either 2T or 4T operation the program-
ming can be reset to “upslope” before reaching
the end amp stage by pressing the switch once
more. See the graphics below for further explana-
tion. The up and down arrows indicate the switch
travel direction.
