SAFETY PRECAUTIONS
SELECT SUITABLE LOCATION
Place the welder where clean cooling air can freely cir-
culate in and out through the rear louvers. Dirt, dust or
any foreign material that can be drawn into the welder
should be kept at a minimum. Failure to observe these
precautions can result in excessive operating temper-
atures and nuisance shut-downs.
GRINDING
Do not direct grinding particles towards the welder. An
abundance of conductive material can cause mainte-
nance problems.
STACKING
Square Wave TIG 185 cannot be stacked.

Eyebolt used for lifting the unit with a hoist. To install;
remove the plug button from the case top and screw
