<Note>

Securely crimp the crimped terminals and securely connect the welding cables. Using
insufficiently crimped terminals or loosely connected cables can result in heat
generation from poor connection, thereby causing burnout of the weld output
terminals.

Be sure to always securely crimp the crimped terminals on the cables connected to
the Weld output terminals. Not using crimped terminals and simply wrapping stripped
cable around the weld output terminal can result in heat generation from poor
connection, thereby causing burnout of the weld output terminals and a short circuit
due to contact of the cable core with the equipment body.

Keep your welding cable and electrode holder in good condition. Repair or replace
any damaged insulation.
9-4. Duty Cycle
The duty cycle is the percentage of time the load is being applied in a 10-minute period.
For example a 60% duty cycle, represents 6 minutes of load and 4 minutes of no-load
in a 10-minute period.
<Note>

Continuing to weld beyond the rated duty cycle with the rated output can result in
equipment overheating and corresponding malfunctions.
9-5. Welding Work
Warning: Suffocation from Welding Fume

Always be sure to wear a fume-proof mask when welding as the fumes generated
during welding include harmful gases and dust. Also be careful that the wind
direction is not such that it will cause fumes to be inhaled and always operate the
equipment in a well-ventilated area.
Warning: Fire

Keep any ignitable items (such as fuel, gas and paint) or inflammable items away
from the work area due to the scattering of weld spatter that occurs during welding.
Warning: Electromagnetic Interference

Persons using a heart pacemaker are not allowed near the welder or welding work
area while welding is being performed without the permission of a doctor. The
welder generates a magnetic field while energized that can negatively affect
pacemaker operation.
Caution: Injury to Eyes and Skin

Always be sure to wear leather gloves, apron, shoe covers, arc-proof glasses (face
shield), safety shoes, hard hat and long-sleeve clothing to protect against the
scattering of weld spatter that occurs during welding.
