The plasma welding process offers two prime benefits:
Improved weld quality and increased weld output. Plasma welding offers
advanced levels of
control, arc stability and weld consistency for high quality welds
either in miniature or precision applications.
The plasma process is equally suited to manual and automatic applications.
It has been used in a variety of operations ranging from high volume
welding of micro components, to precision welding of surgical instruments,
to automatic repair of jet engine blades to the manual welding for repair
of components in the tool, die and mold industry.
The system requires a power supply and welding torch. In the plasma welding
torch a Tungsten electrode is located within a copper nozzle having a
small opening at the tip. A pilot arc is initiated between the torch
electrode and nozzle tip. This arc is then transferred to the metal to
be welded.
By forcing the plasma gas and arc through a constricted orifice, the
torch delivers a high concentration of heat to a small area. With high
performance welding equipment, the plasma process produces exceptionally
high quality welds on a variety of materials.
• |
Protected electrode,
offers long times before electrode maintenance
(usually one 8
hour shift) |
• |
Low amperage welding capability
(as low as 0.1 amp) |
• |
Arc consistency and gentle
arc starting produce consistent welds, time after time |
• |
Stable arc in arc starting
and low amperage welding |
• |
Minimal high frequency noise
issues, HF only in pilot arc start, not for each weld |
• |
Arc energy density reaches
3 times that of GTWA. Higher weld speeds possible |
• |
Weld times as short as .1
secs |
• |
Energy density reduces heat
affected zone, improves weld quality |
• |
Length of arc benefits due
to arc shape and even heat distribution |
• |
Diameter of arc chosen via
nozzle orifice |
|

A self-contained
plasma welding power supply interfaced to DT-100 Weld Programmer and Secheron
Plasma Torch offers complete control of weld parameters for consistent
high quality welds, increased productivity and reduced down time. Accurate
at low amperages, this plasma welding system provides a unique alternative
to more costly processes.
