When using power equipment, basic safety precautions should
always be followed to reduce the risk of fire, electric shock and
personal injury, including the following. If used correctly, weld-
ers pose little risk to the operator; however, care should always
be taken to ensure safety and proper performance. Read all
owner’s operating instructions before attempting to operate any
product.
FOR SAFE OPERATION:
KEEP THE WORK AREA CLEAN: Cluttered working areas
(indoor and outdoor) invite injuries.
CONSIDER THE WORK ENVIRONMENT: Don’t expose power
equipment to rain. Don’t use welding equipment in damp or
wet locations. Keep the work area well lit. Don’t use welding
equipment in the presence of flammable liquids or gases.
GUARD AGAINST ELECTRIC SHOCK: Avoid body contact the
grounded surfaces (e.g. pipes, radiator, and electrical appli-
ances).
KEEP CHILDREN AND VISITORS AWAY: Keep children, infirmed
persons and visitors away from the area of operation. Do not
let children, infirmed persons or visitors touch equipment or
extension cables.
STORE IDLE TOOLS: When power equipment is not in use,
keep them in a dry, high or locked area, out of reach of chil-
dren.
WEAR SAFETY GLASSES: Always wear safety goggles or other
suitable eye protection when using welding equipment.
SECURE WORK: Use clamps or a vice whenever possible to
secure work.
DON’T OVERREACH: Keep proper footing and balance at all
times.

lery. They can be caught in moving parts. Wear protective
hair covering to cover long hair, and gloves and non-slip
footwear is recommended when working outdoors.
TAKE CARE OF CABLES: Never carry welding equipment by
the cable and never pull the cable to disconnect it from a
socket. Keep cables away from heat, oil and sharp edges.
Replace damaged cables.
DISCONNECT TOOLS: Disconnect welding equipment when
not in use, before servicing, and when changing accesso-
ries such as blades, bits and cutters.
AVOID UNINTENTIONAL OPERATION: Don’t carry plugged in
welding equipment with a finger on the switch. Be sure
that the switch is off when plugging in.
OUTDOOR USE EXTENSION CABLES: When electric power
equipment is used outdoors, only use extension cables
marked as suitable for outdoor use.
STAY ALERT: Watch what you are doing. Use common
sense. Do not operate welders when you are tired or under
the influence of alcohol or drugs.
CHECK DAMAGED PARTS: Before using welding equipment,
parts that are damaged should be carefully checked to de-
termine that they will operate properly and perform their
intended function. Any part that is damaged should be
properly repaired or replaced by an authorized service
agent. Have defect switches replaced by an authorized re-
pair agent. Do not operate power equipment if it cannot be
turned off and on by the switch.
REPAIR OF POWER EQUIPMENT BY EXPERTS: Power equip-
ment is built in accordance with relevant safety authority
requirements. The repair of power equipment must only be
carried out by experts; non-expert repairs may cause con-
siderable danger for the user and void warranty.
