5.3
Generator Use
This machine is designed with generator use in mind and incorporates wide voltage tolerance and
intelligent voltage sensing technology to provide maximum protection from power fluctuations that
can occur with motor generators.
5.3.1
Generator Size
Generator size should be not less than 13kva. A 13kVa generator will not provide enough power to
enable full output and duty of this welder. However, it should provide sufficient power to enable
MIG welding up to approximately 200A.
To enable full output and duty cycle of this welder, minimum recommended generator size is 15kVa
or larger.
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.
5.3.3
3 Golden Rules of Generator use
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.
