WILL I CONTAMINATE MY BASE MATERIAL WITH THE TUNGSTEN ELECTRODE?
ere is a possibility of tungsten contamination when the Orion user forces the welding electrode into the weld material.
However, with proper practice using the pulse-arc welding stylus contamination is very unlikely.
DO I NEED TO USE ARGON TO WELD?
Argon is necessary to produce a clean and repeatable pulse-arc weld. Without protective argon, oxygen may combine
with the weld metal to produce brittle and porous welds. In Tack Mode, however, protective argon is not necessary. Other
protective gases can also be used, such as pure nitrogen. However Orion recommends high purity argon. is can be
purchased at your local welding supply shop.
HOW DO I CONTROL WELD SPOT SIZE AND WELD DEPTH?
Simplified answer: Energy adjusts your spot size while your weld time controls penetration. In reality both of these factors
(energy and time) influence both welding characteristics (spot size and weld depth). However, the above rule-of-thumb will
allow good and intuitive control of your welding parameters. It is also important to keep your tungsten electrode sharp to
maintain precise control over the characteristics of the weld spot size and weld depth.
HOW MUCH HEAT IS ADDED TO MY WORKPIECE?
e Orion is capable of extremely fine welds. In low energy settings, small amounts of energy are added and cause virtually
no heat to be added to the workpiece. During small welds involving little energy it is possible to hold the workpiece in hand.
For applications that require higher energy, your Orion (depending on the model) is capable of adding up to 250 Joules (Ws)
of energy to a weld. Until the user is familiar with the welding characteristics of the Orion, we recommend holding all parts
with the pulse-arc attachments (e.g. alligator clip) and not with your fingers.
WHAT IS THE SMALLEST AND LARGEST SPOT SIZE ACHIEVABLE?
e answer to this question depends greatly on the material being welded. However, spot sizes of down to 0.75 mm and up
to 3.5 mm are typical and simple to implement.
HOW DEEP CAN MY PULSEARC WELD PENETRATE?
Depends on the material being welded, however, spot depth of down to 1 mm can be achieved.
HOW LONG WILL ELECTRODES LAST?
Under normal use electrodes will last for approximately 8,000 welds. To ensure that you get the most life out of your
electrodes use argon gas for pulse-arc welding and maintain a sharpened electrode tip during the welding process.
ARE THERE SPECIAL JOINT PREPARATIONS NEEDED WHEN PULSEARC WELDING?
Pulse-arc joint preparation is very similar to that of general “tungsten inert gas” – TIG welding. Some different types of
weld preparation include the simple “I” seam (but joint), X, Y and V joints (named for the way they look). e “I” seam may
require no filler material, while the X, Y and V require filler material and may require successive layers of material to be
added to the joint. For joints were the Orion can penetrate approximately ½ to ¾ of the way through the material an “I”
seam may be appropriate. e weld location should be cleared of solder as this will reduce weld quality.
ARE THERE SPECIAL JOINT PREPARATIONS NEEDED WITH TACK/FUSION WELDING?
Just as in pulse-arc welding, all solder should be removed if a strong metal to metal tack/fusion weld is desired. Tacking
can be used to weld solder in place, or to temporarily tack a workpiece to a solder layer.
CAN I USE TACK MODE TO PLACE SOLDER GRANULES OR PIECES BEFORE A SOLDERING TORCH IS USED?
Yes, this is a very simple process. A variety of hand pieces are available.
