1. Special Precautions
1-2
Do not put your hands between the electrodes
When welding, keep your fingers and hands away from the electrodes.
Do not touch any welded part or electrodes during welding and just after
welding finished
The welded part of a workpiece, electrodes and arm are very hot.
Do not touch them; otherwise you may be burnt.
Do not splash water on the Equipment
Water splashed over the electric parts can cause electric shock and short
circuits.
Connect the specified cables securely
Cables of insufficient current capacities and loose connections can cause fire
and electric shock.
Do not damage the connecting cables
Do not tread on, twist or tense any cable. The connecting cables may be
broken, and that can cause electric
shock and fire. When repair or
replacement is needed, consult us.
Stop the operation if any trouble occurs
Continuous operation after occurrence of a trouble such as burning smell,
abnormal sound, abnormal heat, smoke, etc. can cause electric shock and
fire. If such a trouble occurs, immediately consult us or your distributor.
Persons with pacemakers must stay clear of the welding machine
A person who uses a pacemaker must not approach the welding machine or
walk around the welding shop while the welding machine is in operation,
without being permitted by his/her doctor. The welding machine generates a
magnetic field and has effects on the operation of the pacemaker while it is
turned on.
Protective gear must be worn
Put on protective gear such as protective gloves, long-sleeve jacket, leather
apron, etc. Surface flash and expulsion can burn the skin if they touch the
skin.
Wear protective glasses
If you look at the flash and expulsion directly during welding, your eyes may
be damaged. If any surface flash and expulsion gets in your eye, you may
lose your eyesight.

to remove all combustible matter, cover them with non-combustible material.
Do not cover the Equipment with a blanket, cloth, etc.
If such a cover is used, it may be overheated and burn.
Do not use this Equipment for purposes other than welding
Use of this Equipment in a manner other than specified can cause electric
shock and fire.
Use ear protectors
Loud noises can damage hearing.
Keep a fire extinguisher nearby
Keep a fire extinguisher in the welding shop in case of fire.

・damp places (where humidity is higher than 90%),
・hot or cold places (where temperatures is above 40°C or below 5°C),
・places near a high noise source,
・places where chemicals are handled,
・places where water will be condensed,
・dusty places, and
・places at an altitude above 1000 meters.
■Clean the outside of the Equipment with a soft, dry cloth or one wet with a little
water. If it is very dirty, use diluted neutral detergent or alcohol. Do not use paint
thinner, benzine, etc., since they can discolor or deform the Equipment.
