The welding electrode is a rod coated with a layer of flux. When welding, electrical current
flows between the electrode (rod) and the grounded metal workpiece. The intense heat of the arc
between the rod and the grounded metal melts the electrode and the flux. The most popular
electrodes are:
—E6011 60,000 PSI tensile strength for deep penetrating applications.
—E6013 60,000 PSI tensile strength used for poor fit-up applications.
—E7014 70,000 PSI tensile strength used for high deposition and fast travel speeds with
light penetration.
—E7018 70,000 PSI tensile strength (not suitable for this welder).
This welder is capable of welding with 1/16" (1.6 mm) and 5/64" (2 mm) and 3/32" (2.4 mm)
electrodes.
WELDING POSITION
There are two basic positions for welding: flat and horizontal. Flat welding is generally easier, faster, and
allows for better penetration. If possible, the workpiece should be positioned so that the bead will run on a
flat surface.
PREPARING THE JOINT
Before welding, the surface of the workpiece must be free of dirt, rust, scale, oil or paint, which create a
brittle and porous weld. If the base metal pieces to be joined are thick or heavy, it may be necessary to
bevel the edges with a metal grinder. The correct bevel should be around 60 degrees. See following picture:
Based on different welding positions, there are different welding joints; see following images for more
information:
GROUND CLAMP CONNECTION
Clear any dirt, rust, scale, oil or paint on the ground clamp. Make certain you have a good solid ground
connection. A poor connection at the ground clamp will waste power and heat. Make sure the ground clamp
touches the metal.

OPERATING INSTRUCTIONS
SELECTING THE PROPER ELECTRODE
There is no golden rule that determines the exact rod or heat setting required for every situation.
The type and thickness of metal and the position of the workpiece determine the electrode type
and the amount of heat needed in the welding process. Heavier and thicker metals require more
amperage. It is best to practice your welds on scrap metal which matches the metal you intend
to work with to determine correct heat setting and electrode choice. See the following
troubleshooting tips to determine if you are using the correct electrode
When the proper rod is used:
a.1The bead will lay smoothly over the work without ragged edges.
b. The base metal puddle will be as deep as the bead that rises above it.
c. The welding operation will make a crackling sound similar to the sound of eggs frying.
When a rod too small is used：
a. The bead will be high and irregular.
b. The arc will be difficult to maintain.
When the rod is too large：
a. The arc will burn through light metals.
b. The bead will undercut the work.
c. The bead will be flat and porous.
d. The rod may freeze or stick to the workpiece.

OPERATING INSTRUCTIONS
1. Setting the amperage control
The welder has an infinite output current control. It is capable of welding with 1/16, 5/64, 3/32, 1/8,
and 5/32" electrodes.
There is no golden rule that determines the exact amperage required for every situation. It is best to test
your welds on scrap metal which matches the metals you intend to work with to determine
correct setting for your job. The electrode type and the thickness of the workpiece metal determine the
amount of heat needed in the welding process. Heavier and thicker metals require more voltage
(amperage), whereas lighter and thinner metals require less voltage (amperage).
2. Welding techniques
The best way to teach yourself how to weld is with short periods of practice at regular intervals. All
practice welds should be done on scrap metal that can be discarded. Do not attempt to make any repairs
on valuable equipment until you have satisfied yourself that your practice welds are of good appearance
and free of slag or gas inclusions.
2.1 Holding the electrode
The best way to grip the electrode holder is the way that feels most comfortable to you. To position the
electrode to the workpiece when striking the initial arc it may be necessary to hold the electrode perpendicular to the workpiece. Once the arc is started the angle of the electrode in relation to the workpiece
should be between 10 and 30 degrees. This will allow for good penetration, with minimal spatter.
2.2 Striking the arc
Scratch the work piece with the end of the electrode to start an arc and then raise it quickly to about a
1/8" gap between the rod and the workpiece. See the following picture：
WARNING!
Rate of travel over the work also affects the weld. To ensure proper penetration and
enough deposit of rod, the arc must be moved slowly and evenly along the weld seam.

SNOITCURTSNI GNITAREPO
SNOITCURTSNI GNITAREPO
It is important that the gap be maintained during the welding process and it should be neither too
wide nor too narrow. If too narrow, the rod will stick to the workpiece. If too wide, the arc will
be extinguished. It needs much practice to maintain the gap. Beginners may usually get sticking
or arc extinguishing. When the rod sticks to the workpiece, gently rock it back and forth to make
it release. If not, the circuit will be shorted, and it will overload the welder. A good arc is
accompanied by a crisp, crackling sound. The sound is similar to that made by eggs frying. To
lay a weld bead, only 2 movements are required; downward and in the direction the weld is to be
laid, as in the following figure:
2.3 Types of weld bead
The following paragraphs discuss the most commonly used arc welding beads. The stringer bead
is formed by travelling with the electrode in a straight line while keeping it
centred over the weld joint.
The weave bead is used when you want to deposit metal over a wider space than would be
possible with a stringer bead. It is made by weaving from side to side while moving with the
electrode. It is best to hesitate momentarily at each side before weaving back the other way to
improve penetration.
2.4 Welding position
The flat position is the easiest of the welding positions and is most commonly used. It is best if you can
weld in the flat position if at all possible as good results are easier to achieve.
The horizontal position is performed very much the same as the flat weld except that the angle is different
such that the electrode, and therefore the arc force, is directed more toward the metal above the weld joint.
This more direct angle helps prevent the weld puddle from running downward while still allowing slow
enough travel speed to achieve good penetration. A good starting point for your electrode angle is about 30
degrees DOWN from being perpendicular to the workpiece.
2.5 Judge a good weld bead
When the trick of establishing and holding an arc has been learned, the next step is learning how to run a
good bead. The first attempts in practice will probably fall short of acceptable weld beads. Too long an arc
will be held or the travel speed will vary from slow to fast. See the following picture:
A. Weld speed is too fast.
B. Weld speed is too slow.
C. Arc is too long.
D. Ideal weld.

OPERATING INSTRUCTIONS
A solid weld bead requires that the electrode be moved slowly and steadily along the weld seam.
Moving the electrode rapidly or erratically will prevent proper fusion or create a lumpy, uneven
bead. To prevent ELECTRIC SHOCK, do not perform any welding while standing, kneeling, or lying
directly on the grounded work.
2.6 Finish the bead
As the coating on the outside of the electrode burns off, it forms an envelope of protective gasses
around
the weld. This prevents air from reaching the molten metal and
creates an undesirable
chemical reaction. The burning coating, however, forms slag. The slag formation appears as an
accumulation of dirty metal scale on the finished weld. Slag should be removed by striking the
joined by welding. Peening the weld not
only removes the scale left behind in the welding but
relieves
the internal strains developed by the heating and cooling process. Use a hammer or brush
after the workpiece has cooled.
MAINTENANCE
The welder needs regular maintenance:
• Periodically clean dust, dirt, grease, etc. from your welder. Every six months, or as necessary,
remove the cover panel from the welder and air-blow any dust and dirt that may have accumulated
inside the welder.
• Replace power cord, ground cable, ground clamp, or electrode assembly when damaged or worn.
• Store in a clean dry facility, free from corrosive gas, excess dust and high humidity. Store in a
temperature range from -12 to 49ºC (10 to 120ºF) and relative humidity not more than 90%.
• When transporting or storing the welder after use, it is recommended to repack the product as it
was received for protection. Cleaning is required before storage and you must seal the plastic bag
in the box for storage.
