PREPARATION
Unpacking and completing the assembly should
be done on a flat and stable surface, with enough
space for moving the machine and its packaging,
always making use of suitable equipment.
WARNING
Always unplug your machine from power source
before any adjustment.

OPERATION
WARNING
Do not operate the machine if the power cable,
ground clamp, torch cables and any wire or wire
connections are wet. Do not immerse them in wa-
ter. These components and the machine must be
completely dry before attempting to use them.
Connect the ground clamp as close to the welding
area as possible to ensure a good ground. Do not
allow any body part to come in contact with the
welding torch head if you are in contact with the
material being welded. Do not drape cables over
or around your body. Always use the device with-
in its rated duty cycle to prevent overheating and
breakdown. Allow proper cooling time between
duty cycles. Do not point welding torch at any
body part of yourself or anyone else.
NOTE
This is a sensitive electronic device, do not abrupt-
ly change or adjust the welding, otherwise the de-
vice will be damaged.
SETTING UP THE UNIT
Make sure there is at least 50cm free space around
the machine in order to have good ventilation.
Connect the power supply cable to the power
supply.
MMA WELDING
The welding electrode is a metal rod coated with
a layer of flux. When welding, electrical current
flows between the electrode and the grounded
metal work piece. The intense heat of the arc
between the rod and the grounded metal melts
the electrode and the flux. The type and thick-
ness of metal and the position of the work piece
determine the electrode type and the amount of
heat needed for the welding process. Heavier and
thicker metals require more amperage. It is sug-
gested to practice on scrap metal which matches
the metal intended to work with in order to de-
termine correct welding settings and electrode
choice. The material to be welded should be clean
and free of any moisture, paint, oil, grease, mill
scale, rust or anything else that will hinder the arc
and contaminate the weld material. Joint prepa-
ration will depend on the method used include
sawing, punching, shearing, machining, flame cut-
ting and others. In all cases edges should be clean
and free of any contaminates. The type of joint
will be determined by the chosen application.
1. Connect the ground clamp to the ground clamp
connector and the electrode holder to the elec-
trode holder connector (Fig. 3.2).
NOTE
If acid electrodes are to be used the ground clamp
must be connected to the electrode holder con-
nector and the electrode holder to the ground
clamp connector (FIg. 3.1) . When using acid elec-
trodes the arc is frequently broken.
2. Place the electrode οn the electrode holder.
3. Turn on the device by setting the the On/Off
switch (Fig. 1.7) to ON position.
4. Firmly attach the ground clamp to the work
