10. Simultaneous Use of Welding and Generating The circuit breakers (3-P and 1-P) react on the AC power supply circuit only. In the
simultaneous use of welding and generating, there sometimes happens overload to the
engine. Refer to the following table and limit the AC power use.

φ6.0mm/300A Single 2.0kVA 2.5kVA
φ8.0mm/380A Single 0kVA 0kVA
In order to secure stable AC output, the output selector switch should be positioned
to DUAL in operation as long as possible.
The 1-Phase output is the total of 1-Phase from the receptacle and 1-Phase from
terminals.
<Caution>
z The simultaneous use of Eco welding and AC power is NOT available.
z Avoid the simultaneous use in the case high quality result in welding is
required.
Danger : Electric Shock Injuries
z Before performing any equipment check or maintenance, stop the engine, and
remove engine key. A person performing the maintenance should always keep
the key.
Caution: Fire Burns
z Keep the equipment far away from fire.
z When checking engine, always stop the engine, and keep away from fire. Wait
until the engine cools down, before performing any checks.
<Caution>
z The authorized technicians should perform all checking and maintenance work,
except for the pre-startup checks.
z Request for the maintenance item with ● mark to the authorized distributor or
our engineering section.
z Always use our genuine parts of replacement.
To optimize the use of this generator/welder, we recommend the periodical equipment
checks and maintenance based on the following matrix.
Use the hour meter as a guide for the operating time.
