ARC® Iron Powder Low Hydrogen Electrodes
The introduction of iron powder into
low hydrogen electrodes greatly increased productivity, making the use
of Atom Arc for most welding operations
more than competitive with common mild steel electrodes in overall
cost. The real advantage of course
is that by improving the efficiency of welding operations, fabricators
have a means of equalizing increasing
overhead and labor costs. Moisture
Resistant Coating Atom
Arc electrodes are manufactured with a flux coating that effectively resists
moisture pick-up for many hours
after the container is opened. This improved coating provides an extra degree
of reliability, especially for
electrodes exposed to high temperature, high humidity working conditions.
Typical % Moisture in Atom Arc Coatings
It should be noted that even though
Atom Arc electrodes resist moisture pick-up longer than ever before, no
moisture resistant electrode will eliminate
the need for storage and rebake ovens or the necessity to follow
code requirements for allowable exposure
times. The graph
above shows the rate of moisture pick-up of Atom Arc electrodes.
