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 electrode holder are very hot.
Do not touch them; otherwise you may be burnt.
Apply the specified power supply
Application of a voltage out of the specified range can cause fire and electric
shock.
Stop the operation if any trouble occurs
Continuous operation after occurrence of a trouble suc
h 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.
Wear protective glasses
If you look at the surface flash and expulsion directly during welding, your eyes

Do not splash water on the Unit
Water splashed over the electric parts can cause electric shock and short
circuits.
Use proper tools (
wire strippers, pressure wire connectors, etc) for
termination of the connecting cables
Do not cut the conductor of wire. A flaw on it can cause fire and electric shock.
Do not damage the power cable and connecting cables
Do not tread on, twist or tense any cable. The power cable and connecting
cables may be broken, and that can cause electric shock and fire.
When you need any repair or replacement, consult us or your distributor.
Connect the specified cables securely
Cables of insufficient current-
carrying capacities and loose connections can
cause fire and electric shock.
Install the Unit on firm, level surface.
If the Unit falls or drops, injury may result.
Keep combustible matter away from the welding machine.
Surface flash and expulsion can ignite combustible matter. If it is impossible to
remove all combustible matter, cover them with non-combustible material.
Do not cover the Unit with a blanket, cloth, etc.
If such a cover is used, it may be overheated and burn.
Keep a fire extinguisher nearby.
