Environmental Rating
The PRECISION TIG® 225 power source carries an
IP21S environmental rating. It may be used in normal
industrial and commercial environments. Avoid using it
in environments which have falling water such as rain.
Read and follow "Electric Shock Warnings" in the
Safety section if welding must be performed under
electrically hazardous conditions such as welding in
wet areas or on or in the workpiece.
• The PRECISION TIG® 225 must be located where
there is free circulation of clean air such that air
movement in and out the back air vents will not be
restricted.
• Dirt and dust that can be drawn into the PRECISION
TIG® 225 should be kept to a minimum. Failure to
observe these precautions can result in excessive
operating temperatures and nuisance shutdown.
GRINDING
Do not direct grinding particles towards the welder. An
abundance of conductive material can cause mainte-
nance problems.
STACKING
PRECISION TIG® 225 cannot
be stacked.
LIFTING AND MOVING
The PRECISION TIG® 225 models are provided with
an Eyebolt used for lifting the unit with a hoist.
To install; remove the plug button from the case top
and screw the Eyebolt securely into the threaded
bracket beneath the case top per the below instruc-
tions and warnings provided on the case top decal.
Save the removed plug button (LE part No.T10397-2)
to cover the hole when the lift Eyebolt is removed.
An undercarriage, provided on the Ready-Pak™
w/Cart model, is also available to easily move the unit.
Refer to the Accessories section of this manual.
Do not attempt to lift the power
source with an undercarriage
attached.
The undercarriage is designed for hand moving only;
mechanized movement can lead to personal injury
and/or damage to the PRECISION TIG® 225.
TILTING
Each machine must be placed on a secure, level sur-
face, either directly or on a recommended undercar-
riage. The machine may topple over if this procedure is
not followed.
ELECTRIC SHOCK can kill.
