e penetration of your weld spot depends on many different factors. However, as a rule of
thumb you can expect the penetration of the weld spot to be approximately ¼ of the diameter of
the weld spot. Factors like electrode shape and condition also effect the weld penetration and will
be discussed in more detail later.
PULSE ARC VS. LASER
Laser welding and pulse arc welding technologies are designed to create high quality welds in
precious and non precious metals. Laser welding uses collimated or focused light to add energy
to the metal and melt it at a single location. Pulse Arc welding uses electricity (specifically
electrons) to add energy to the work piece and melt the metal in a spot. Although laser welding
devices are good welding tools, the Orion can perform many of the same functions of a laser
and in some cases can even perform actions that lasers cannot. For example, welding silver is
difficult for laser light because of silver’s highly reflective properties. However, the Orion does
not have this limitation because electrons are electrically attracted to the surface of silver. e
Orion also has the advantage of only welding on metal. Lasers can strike precious stones or other
nonmetals and can even crack or evaporate the target. Because the Orion is electrically driven it
requires a conductor, such as a metal, to allow the welding process to take place.
e Orion welder uses the same high temperature plasma that can be
found on the surface of the sun. e sun creates this plasma via internal
fusion reactions and the plasma temperature measures about 5,500
deg C at the sun’s surface. e Orion creates it’s plasma via electrical
discharge and can generate temperatures of 5,500 – 8,000 deg C in very
controlled, small bursts.

To become an expert and to really learn how to maximize the capabilities of the Orion, we
recommend that you dedicate time for real hands on experience. We recommend that you read
and complete the following sections while you are in front of the Orion. e Orion is very easy-to-
use and many users will be making quality welds within minutes. e purpose of this section is to
help the user to better understand some of the fundamental welding principles, to utilize all of the
