5.3.2 Generator Quality & Warranty Limitations

Avoid using poor, low quality generators as these have the greatest risk of power spikes etc. A

suitable quality generator should have a THD (total harmonic distortion) rating of no more than 6%.

Most reputable generator suppliers will be able to specify the THD ratings on their product.

Any damage caused by poor quality generator power supply or incorrect use is not covered under

warranty.

When running an inverter welder off a generator there are 3 VERY IMPORTANT Golden Rules that

MUST be followed:

1. Do NOT plug welder into generator until AFTER generator has been started up and is running

smoothly

2. UNPLUG welder from generator BEFORE shutting generator down/turning generator off

3. NEVER let your generator run out of fuel whilst the welder is plugged in.

Following these Golden Rules will significantly reduce the risk of any damage resulting from

generator power supply.

6.1

The machine has electrical components and control circuit boards which may be damaged by excessive

moisture, dust and dirt, so a clean and dry operating environment is important for reliable product life.

The enclosure design of this power source meets the requirements of IP23S as outlined in AS60529.

This provides adequate protection against solid objects (greater than 12mm), and direct protection

from vertical drops. Under no circumstances should the unit be operated or connected in a micro

environment that will exceed the stated conditions. For further information please refer to AS 60529.

6.2

Adequate ventilation is required to provide proper cooling for the machine. Ensure that the machine

is placed on a stable level surface where clean cool air can easily flow through the unit.
