Additional Hazards For Installation, Operation, And Maintenance - Miller Dynasty 280 Series Owner's Manual

CYLINDERS can explode if
damaged.
Compressed gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the wel-
ding process, be sure to treat them carefully.
� Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, physical damage, slag, open flames, sparks, and arcs.
� Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
� Keep cylinders away from any welding or other electrical circuits.
� Never drape a welding torch over a gas cylinder.
� Never allow a welding electrode to touch any cylinder.

Additional Hazards For Installation, Operation, And Maintenance

FIRE OR EXPLOSION hazard.
� Do not install or place unit on, over, or near com-
bustible surfaces.
� Do not install unit near flammables.
� Do not overload building wiring - be sure power
supply system is properly sized, rated, and protected to handle
this unit.
FALLING EQUIPMENT can injure.
� Use lifting eye to lift unit and properly installed ac-
cessories only, NOT gas cylinders. Do not exceed
maximum
Specifications).
� Use correct procedures and equipment of adequate capacity to lift
and support unit.
� If using lift forks to move unit, be sure forks are long enough to ex-
tend beyond opposite side of unit.
� Keep equipment (cables and cords) away from moving vehicles
when working from an aerial location.
� Follow the guidelines in the Applications Manual for the Revised
NIOSH Lifting Equation (Publication No. 94-110) when manually
lifting heavy parts or equipment.
OVERUSE can cause
OVERHEATING.
� Allow cooling period; follow rated duty cycle.
� Reduce current or reduce duty cycle before start-
ing to weld again.
� Do not block or filter airflow to unit.
FLYING SPARKS can injure.
� Wear a face shield to protect eyes and face.
� Shape tungsten electrode only on grinder with
proper guards in a safe location wearing proper
face, hand, and body protection.
� Sparks can cause fires — keep flammables away.
STATIC (ESD) can damage PC
boards.
� Put on grounded wrist strap BEFORE handling

ciated equipment, and Compressed Gas Association (CGA) publi-
cation P-1 listed in Safety Standards.
MOVING PARTS can injure.
� Keep away from moving parts.
� Keep away from pinch points such as drive rolls.
WELDING WIRE can injure.
� Do not press gun trigger until instructed to do so.
� Do not point gun toward any part of the body, other
people, or any metal when threading welding wire.
BATTERY EXPLOSION can injure.
(see
� Do not use welder to charge batteries or jump start

designed for this purpose.
MOVING PARTS can injure.
� Keep away from moving parts such as fans.
� Keep all doors, panels, covers, and guards closed
