The Power to Perform!SM
Professional features, like the most
auxiliary power and the widest output range
in its class, make the Precision TIG®225 a
great value.
FEATURES
5-230 amps is the widest welding range
in its class.
Patented Micro-Start™II Technology
delivers extremely stable low amperage
starting, welding and cratering for AC and
DC welding.
FREE TIG Pulser – Optimal heat input
control results in reduced warping and
burnthrough on thin materials and
improved appearance.
Excellent Stick Welder – even with
Fleetweld®5P (E6010).
AC Auto Balance®automatically sets the
optimal cleaning vs. penetration levels for
great looking aluminum welds.
115 volt auxiliary power receptacles
with 20 amp service reliably powers
water coolers or other tools (208/230V
model only, all other models 6 amps).
Standard torch parts storage
compartment and cable hanger keeps
you organized.
Fan-As-Needed™(F.A.N.) prevents
overheating. F.A.N. reduces power
consumption noise, motor wear and dust
in the machine.
CSA C/US certified.

Precision TIG®225 | [ 3]
“Set It/See It” Pulse Control —
Make attractive and consistent welds!
What Is It?
Pulse welding systems vary weld current between peak (high heat) and
background current (low heat) levels. Adjusting the pulse frequency
controls the level of heat input applied to the weld relative to the weld
travel speed. For the Precision TIG®225, pulse frequency can be varied
from 0.1 to 20 pulses per second.
Results
Better control of heat input in the weld, resulting in:
•Reduced warping and burnthrough on thin materials.
•Smaller heat-affected zone.
• Smaller bead profile without compromising proper penetration.
Great For
•Thin materials – Faster pulse settings help to narrow the bead
profile and minimize the heat-affected zone and resulting warping
or burnthrough.
• Consistent appearance – Slower pulse settings aid in timing the
application of filler metal to produce the consistent stacked bead
appearance associated with high quality TIG
welding.
•Maintaining a steady welding rhythm.
Easy Operation:
• Flashing indicator light lets you see the
pulse rate before you strike an arc.

AC Auto Balance®Controls —
Automatically sets the optimal cleaning vs. penetration
level for aluminum welding!
What Is It?
When aluminum welding, the positive (+) portion of the AC welding
amperage cleans the oxides from the aluminum surface. The negative (-)
portion delivers more heat input, increasing penetration level.
Patented AC Auto Balance®automatically sets the ratio of
cleaning action (+) versus penetration (-) based on amperage.
Manual balance control provides the flexibility to customize
the arc to your preference.
Easy Operation:
• Set it and forget it or override when you choose to customize
the settings.
