3. ELECTRODE
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 work piece. The intense heat of the arc
between the rod and the grounded metal melts the electrode and the flux.
4. 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 work piece 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 metals which match 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 a correct electrode.
a. When the proper rod is used:
i. The bead will lay smoothly over the work without ragged edges.
ii. The base metal puddle will be as deep as the bead that rises above it.
iii. The welding operation will make a crackling sound similar to the sound of eggs
frying.
b. When a rod is too small is used:
i. The bead will be high and irregular.
ii. The arc will be difficult to maintain.
c. When the rod is too large:
i. The arc will burn through light metals.
ii. The bead will undercut the work.
iii. The bead will be flat and porous.
iv. The rod may freeze or stick to the work piece.
Note: The 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 an infinite current control. It is capable of welding with electrodes up to 3/32”
diameter. It is best to practice your welds on scrap metals which match 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.
