All-State®
Chamfer Rod Electrode
for Chamfering, Gouging, Veeing Out, and Beveling of All Metals
AC or DC Straight Polarity (Electrode
–) All Position General
Characteristics A
specially designed electrode with a heavier flux than that used on All-State®
Cutting Electrodes. This flux serves two
purposes: 1) protects the core wire from overheating due to high amperages; 2)
produces large volumes of gas
to remove more material per electrode. Any AC or DC welding machine with sufficient
capacity will operate this
electrode thus eliminating the use of an air compressor, special equipment, or
expensive gases. Typical
Applications Chamfering
and gouging of both ferrous and nonferrous metals. When chamfering and beveling
cast iron, it not only
produces a clean groove but the arc “sears” the base metal and burns
out grease, oil, moisture and some of
the excess carbon. On stainless steel, this electrode is superior to oxygen/fuel
torches that use mild steel rods
or powders because: 1)
there is less oxidation of the weld zone since it is surrounded with ionized metal
instead of oxygen; 2)
less carbide precipitation because the chamfering speed is so fast, the weld area
is held at the critical heat range
for a shorter time. Procedures
The use of DC straight polarity will
produce the cleanest, fastest grooves, but AC may be used. Hold electrode
at a low angle to the work (between
7 and 15 degrees). Strike the arc, point electrode in the direction of travel,
and push the
electrode along the line to be cut. Keep the electrode in contact with the work
and move as fast as possible.
If a deeper cut is required, repeat in the same groove until desired depth is
reached.
