PRODUCT DESCRIPTION
The PRECISION TIG 185 is a member of our field
acclaimed Precision TIG family of industrial arc weld -
ing power sources. Premium features include:
1. Precise constant current output.
2. Full range square wave AC/DC TIG (GTAW) weld--
ing.
3. Enhanced version of the patented Micro-
Start™Technology for its lower Minimum(5 amps)
to higher Maximum (185 amps) output control
range.
4. Built-in high frequency stabilization for DC TIG
starting and continuous AC TIG welding.
5. AC/DC Stick (SMAW capability.) A new undercar-
riage (with gas bottle rack) is available for field
installation, or is included with an available Ready-
Pak TIG Welding Package. The Precision TIG
patented convenient built-in storage provisions for
welding components and cable management.
The PRECISION TIG 185 also provides advanced
features such as:
• Digital Meter
• Presettable control, adjustable Auto Balance™
• Fan As Needed (F.A.N.)
• Timers for fixed Preflow and variable Postflow
shielding gas.
• Built-in, easy to set single knob Pulse TIG control
with a "blinking" light to indicate the pulse frequency
setting.
• Auto-Sense remote control selection.
• Tool-less Twist-Mate electrode cable connection.
• Built-in work clamp cable permanently attached.
Four models are available for 60Hz. with Domestic
and Canadian input voltages, as well as an
International model with 50/60Hz voltages.
RECOMMENDED PROCESSES AND
EQUIPMENT
RECOMMENDED PROCESSES
The PRECISION TIG 185 is recommended for the
TIG (GTAW) and Stick (SMAW) welding processes
within its output capacity range of 5 amps DC,or 7
amps AC, to 185 amps AC/DC. It is compatible with
most Magnum TIG accessories, as well as many
industry standard items, such as TIG torches (adapted
for Twist-Mate), hoses, and water coolers.
PROCESS LIMITATIONS
The PRECISION TIG machines are not recommended
for arc gouging due to it's limited output capacity, and
are also not recommended for pipe thawing.

EQUIPMENT LIMITATIONS
The PRECISION TIG machines are protected from
over loads beyond the output ratings and duty cycles,
per the Specifications in the Installation Section, with
Thermostat protection of the output power coils and
rectifiers.
The PRECISION TIG 185 machine uses Twist-Mate
output terminals, therefore stud connection adapters
(such as LECO. S19257-series) cannot be used for
torch connection.
If a PRECISION Tig 185 is powered from an engine
generator which doesnʼt have sufficient capacity, the
AC Balance control and the Output control will not
provide full range of control.
WELDING CAPABILITY(Duty Cycle)
The PRECISION TIG 185 is rated at 185 amps, 27
volts, at 15% duty cycle on a ten minute basis. It is
capable of higher duty cycles at lower output currents.
See rated output graph, on specification sheet located
in the Installation Section. If the duty cycle is exceed-
ed, a thermal protector will shut off the output until the
machine cools.
