Improved Thermal Arc 186 AC/DC TIG Welder
Features Operator-friendly Interface, 15 Amps More TIG Welding Power
For fabricators looking to weld ferrous and non-ferrous metals in the
field and the shop, Victor Technologies has redesigned its Thermal Arc 186 AC/DC inverter for HF TIG, Lift TIG and Stick welding. When
compared to its predecessor, the Thermal Arc 185, the Thermal Arc 186
features 15 amps more TIG welding power, sports a new digital
operator interface that makes setting weld parameters more intuitive
and delivers it all at a lower price of $1,899.
Thermal Arc 186 AC/DC provides a welding output of 10 to 200 amps
with a duty cycle of 20% when TIG welding 200 amps/18 volts. Stick
welding duty cycle is 16% when welding at 120 amps/26.6 volts and is
suitable for welding with 6011, 6013, 7014, 7018 and other electrodes
up to 5/32” diameter.
unit weighs 48.4 lbs., uses 208-230V input power and provides
advanced AC wave shaping and pulsed DC TIG controls that enable
operators to improve weld puddle control, control the weld bead
profile, reduce heat input and increase travel speeds. The Thermal
Arc 186 AC/DC is designed for mobile contractors and fabricators, as
well as applications in the aircraft/aerospace, appliance,
maintenance/repair, automotive, boat and trailer industries.
to conventional technology TIG welders and inverters with fixed
parameters settings, the Thermal Arc 186 AC/DC enables tailoring the
TIG welding arc to the application or for operator preferences,”
Wilton, Vice President, Global Welding Products, Victor Technologies.
“Further, with a list price of $1,899, the Thermal Arc 186 AC/DC
inverter offers more features than any other welder in its price
Thermal Arc 186 AC/DC’s advanced TIG controls can improve results
when welding aluminum, stainless steel, chrome-moly and thin metal.
wave balance control,
adjustable between 10 and 65% electrode negative (EN). Lesser
amounts of EN increase “cleaning action” to remove aluminum
oxide, while greater amounts increase penetration.
adjustable between 15 and 150 Hz. Higher frequencies produce a
narrower, more forceful arc cone that helps direct the arc at the
root of the joint in fillet welds and increase penetration and
travel speeds. Frequency control especially improves aluminum
TIG welding controls,
with a pulse frequency adjustable between 0.5 and 200 pulses per
second (PPS) and a peak pulse width (pulse duration) adjustable
between 15 and 80%. Stainless steel fabricators and those working
thin metals or other heat-sensitive applications use pulsed TIG to
reduce heat input, narrow the weld bead profile and increase travel
speed. A slow frequency, such as 1 PPS, acts as a “metronome” so
that beginners can establish a good cadence for adding filler rod.
and downslope/crater control,
which respectively provide more control during arc starts to prevent
excessive heat input and ramp down the current at the end of the
weld to help prevent crater cracking.

positive arc starts without HF.
that operators can take full advantage of the Thermal Arc 186’s
features, we included a set-up guide on top of the unit with
recommend parameters,” says Wilton. “Push buttons, LED displays
and a multi-function control knob make setting parameters much
easier. We completely overhauled the operator interface to create a
Thermal Arc family look similar to our new 3-in-1 series of welders.”
Thermal Arc 186 AC/DC also provides advanced Stick welding controls,
including adjustable Stick
Arc Force and Hot Start Control. These features allow end users to
adjust arc characteristics to optimize performance for different
electrodes and help prevent the electrode from sticking.
