2T/4T Torch Trigger Selector.
The torch trig-
ger function is designed to operate for both
MIG and TIG functions. To operate in 2T
mode, the trigger on either the MIG or TIG
torch should be simply held down. The 4T
function operates as a torch “latch” in MIG
mode that locks the MIG torch on without
needing to hold the trigger. To operate 4T in
the MIG mode, simply press the torch trigger
and hold it down until the arc starts. To lock it
on, release the trigger and weld without hold-
ing the trigger down. To stop, the trigger must
be pressed again, and then released after 1-2
seconds. The 4T function in TIG mode acts sim-
ilarly, but in conjunction with the down slope
timer. As the torch trigger is pressed for the
second time, the trigger should be held in until
the downslope timer completes its cycle. The
the trigger may then be released to end the
arc. Releasing before the down slope is fin-
ished will terminate the arc immediately.
NOTE: The unit will always default to 4T op-
eration each time the unit is powered on.
13.
Process Selector.
Each icon graphically repre-
sents each process for rapid eye acquisition
when changing processes. The top function
represents MIG. The middle function repre-
sents Stick. The bottom function represents
TIG.
Note: The unit will default to MIG each
time the power is cycled on.
14.
Volt Display.
The display displays MIG volts
that are selected either through the automatic
synergic function (200S) or through the manual
adjustments made with the MIG Volt control
knob. The function of the Volts display will
change to reflect actual welding volts during
welding. This may reflect a slightly different
voltage than selected. This is normal and due
to minor variations of arc length, power input
etc. The Volt meter also registers TIG and Stick
voltage, though the voltage is non adjustable
on these functions.
15.
Power Indicator.
This L.E.D. should remain
on while the switch is on.

Duty Cycle/Overcurrent/Over or Under
-
Voltage Warning.
When the duty cycle has
been exceeded or an overcurrent, over-voltage
or under-voltage condition has occurred, the
L.E.D. will light. Allow the unit to cool while
running until the light goes off or for 10
minutes before resetting the welder. If condi-
tion persists check for loose wires or voltage
supply problems.

Connect the Gas regulator hose
to this point via the brass fitting. (Regulator is

Power Input Cable.
The MTS requires a
220/240 V single phase 50/60 Hz power input.
Do not attempt to hook to any other power
configuration. See page 13 for proper wiring
instructions. If used on a generator, the gener-
ator must labeled as “clean power” and pro-
vide a sine wave with less than 10% variation.

Wire spool holder assembly.
See page 21 for
the detailed view. Make note of the correct
assembly order of the rubber tension washers
and spring.
The order in which they are as-
sembled is important to be able to provide
enough resistance to prevent de-spooling of
the wire.
When inserting the spool , make
sure the small tab on the inside of the spool
holder is located in one of the recesses made
into the spool, if any. Tighten the outer hand
nut after installing the wire spool so that the
wire will not continue to keep rolling after
wire has stopped feeding. Do not over tighten
so that the drive rolls slip or the feeder strains
to pull the wire. The tensioner assembly can
accommodate either 8” or 4” spools of wire.
However, the black center adapter must be
removed to use the smaller rolls.
2.
Polarity Buss Bar.
Note the “+” and “-” sym-
bols located on the inside of the unit next to
the buss bar terminals. To change the polarity
of the MIG torch, simply loosen the middle
screw and remove the top and bottom screws
on the terminals. By pivoting the buss bar on
the center, loosened screw., swing the buss
bar into position over the desired polarity. Re-
install the screws, lining up the holes in the
buss bar with the terminal. Tighten all buss
bar screws. Always remember to alter your
work clamp to reflect the polarity change. If
the terminal buss bar is oriented to negative,
then the work clamp should be in the “+” posi-
