nonflammable surface.
9.
If too much current is drawn from the
welder;
the
Thermal
Overload
protector will activate, the Overload
indicator will light, and the welder will
turn off until it cools down. It will
automatically reset.
Arc (stick) Connection
1. Connect the Electrode Clamp and
Cable to the torch control connector
(as 7 shown on page 9 and twist to
lock in place.
2. Plug the cable of the Grounding
Clamp into the DC ground connector
and secure the clamp to a clean,
exposed metal part of the workpiece.
3. Place the metal portion of the welding
rod inside the jaws of the Electrode
Clamp. Welding rod types vary for
welding different metal
DANGER! To prevent serious injury
and death: If the operator is not
holding the Torch, it must be sitting
on a nonconductive, nonflammable
surface. The Stick Welder will
immediately turn on when the
power button is turned on.
Stroke the work piece lightly to ignite
the arc. Do not strike like a match?
Never tap the electrode wire to ignite
the arc; it will damage the electrode.
4. When the arc ignites, tilt the electrode
forward and hold it near the work
piece.
5. If too much current is drawn from the
welder;
the
Thermal
Overload
protector will activate, the Warning
indicator will light, and the code 804
will be showed on the digital display, at
the same time, the welder will turn off
until it cools down. It will automatically
reset.
When finished welding
a. Release the Torch handle trigger
and lift the Torch handle from the
work piece,
b. Press the Power Switch to the Off
(O) position.
c. Set the Torch handle down on the
metal workbench,
d. Turn the air supply off, Unplug the
line cord from the electrical outlet
Tungsten Inert Gas

welding
,
is an arc welding process that uses a non-consumable tungsten electrode to produce the
weld. The weld area is protected from atmospheric contamination by a shielding gas
(usually an inert gas such as argon), and a filler metal is normally used, though some
welds, known as autogenously welds, do not require it. A constant-current welding power
supply produces energy which is conducted across the arc through a column of highly
ionized gas and metal vapors known as plasma. TAW is most commonly used to weld thin
sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and
copper alloys. The process grants the operator greater control over the weld than
competing procedures such as shielded metal arc welding and gas metal arc welding,
allowing for stronger, higher quality welds. However, GTAW is comparatively more
complex and difficult to master, and furthermore, it is significantly slower than most other
