Tool Set Up
TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION:
Turn the switch to its off
position before performing
any inspection, maintenance,
or cleaning procedures.
IMPORTANT: This Welder requires 1.
the attachment and use of a UL
®
listed, 240 volt, grounded, 3-prong,
electrical Power Cord Plug (not
included). Only a qualied electrician
should install the Power Cord Plug.
Never remove the grounding prong or
modify the Plug in any way. Do not
use adapter plugs with this Welder.

Work Piece and Work Area Set Up
Designate a work area that is clean 1.
and well-lit. The work area must not
allow access by children or pets to
prevent injury and distraction.
Route the Power Cord (17) along a 2.
safe route to reach the work area
without creating a tripping hazard
or exposing the Power Cord to pos-
sible damage. The Power Cord must
reach the work area with enough
extra length to allow free movement
while working.
Secure loose work pieces using a 3.
vise or clamps (not included) to pre-
vent movement while working. The
work pieces should be rmly held to-
gether and in position while welding.
The distance (if any) between the
two work pieces must be controlled
properly to allow the weld to hold
both sides securely while allowing the
weld to penetrate fully into the joint.
There must not be hazardous ob-4.
jects, such as utility lines or foreign
objects, nearby that will present a
hazard while working.
A barrier, such as a welding curtain 5.
or welding shroud should be put up
to protect others in the work area and
limit the spray of sparks.
