1. When proper rod is used:
a. The 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
2. When a rod too small is used
a. The bead will be high and irregular b. The arc will be difficult to maintain
3. 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. Rod may be freeze or stick to work piece
Note: Rate of travel over the work also affects the weld. To ensure proper pe-
netration and enough deposit of rod, the arc must be moved
slowly and evenly along the weld seam.
Operation
1.Setting the amperage control
The welder has an infinite output current control. It is capable of welding
with 1/16" and 5/64" and 3/32" electrodes.
here is no golden rule that determines the exact amperage required for eve-
ry situation. It is best to practice 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 work piece 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).
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 appea-
rance and free of slag or gas inclusions.
Holding the electrode
The best way to grip the electrode holder is the way that feels most comfor-
table to you. To Position the Electrode to the work piece when striking the
initial arc it may be necessary to hold the electrode perpendicular to the
work piece. Once the arc is started the angle of the electrode in relation to
the work piece should be between 10 and 30 degrees. This will allow for good
penetration, with minimal spatter.
