4.3b. The bead will undercut the work
4.3c. The bead will be flat and porous
4.3d. Rod may freeze or stick to work piece
Note: 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.
5. SETTING THE AMPERAGE CONTROL
The welder has current control that is infinitely adjustable within its range. It is capable of welding
with electrodes up to 3/32ʺ diameter. There is no golden rule that determines the exact amperage
required for every 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). Consult the welding electrode packaging for recommended
welding amperage range.
6. 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 are satisfied that the appearance of your practice welds is of
good appearance and free of slag or gas inclusions.
6.1 Holding the electrode:
The best way to grip the electrode holder is the way that feels most comfortable to you.
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.
6.2 Striking the arc
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc or
begin welding until you are adequately protected. Wear flame-proof welding gloves, a heavy
long-sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved welding
helmet.
Scratch the work piece with the end of electrode to start arc and then raise it quickly about
