SELECT SUITABLE LOCATION

Locate the welder in a dry location where there is free
circulation of clean air into the louvers in the back and
out the front of the unit. A location that minimizes the
amount of smoke and dirt drawn into the rear louvers
reduces the chance of dirt accumulation that can block
air passages and cause overheating.
STACKING

TILTING
Each machine must be placed on a secure, level sur-
face, directly or on recommended cart. The machine
may topple over if this procedure is not followed.
