General Operating Instructions
Protective gear
must be worn when using the
Arc Welder; ANSI-approved,
arc shaded, eye protection,
a full face shield, heavy-duty
work gloves, a welding apron,
NIOSH-approved respirator,
and heavy-duty work clothes
without pockets should be
worn when using this product.
Do not look at the ignited
arc without eye protection.
Light from the arc can cause
permanent damage to the
eyes. Light from the arc can
burn the skin. Do not breathe
arc fumes.
The duty cycle denes the number of 1.
minutes, within a 10 minute period,
during which a given Welder can
safely produce a particular welding
current. For example:
At a • 10% duty cycle (at 130 Amps
AC), actual welding can occur for
one minute and then the welder
must cool for nine minutes.
At a • 15% duty cycle (at 100 Amps
DC), welding can occur for 1.5
minutes and then the welder must
cool for 8.5 minutes.
Failure to carefully observe duty cy-•
cle limitations can stress a Welder’s
power generation system, contribut-
ing to premature Welder failure.
This Welder is equipped with an inter-2.
nal thermal protection system to help
prevent damage to the unit. When
the Arc Welder overheats the Yellow
Lamp (24) is illuminated on the con-
trol panel and the unit automatically
shuts down. Then the unit returns to
service when it cools down and the
Yellow Lamp turns off automatically.
(See Figure B.)
Once the unit returns to service, •
follow a more conservative duty
cycle routine to help prevent excess
wear to the Welder.
Determine whether AC or DC welding 3.
is to be used.
Connect the Grounding Cable with 4.
Clamp (34) and Welding Cable with
Electrode Holder (33) for either AC or
DC operation. (See Figure B.)
