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
Weldforce 210MST:
Generator size should be not less than 7kva, preferably 8kva or more. A 7kVa
generator will not provide enough power to enable full output and duty cycle, however it should
provide sufficient power to enable MIG welding up to approximately 150A. This means it should
successfully weld with 0.9mm gasless wire and material thickness of up to approximately 4-5mm
steel.
To enable full output and duty cycle, minimum recommended generator size is 10kVa.
Weldforce 250MST:
Generator size should be not less than 13kva. A 13kVa generator will not
provide enough power to enable full output and duty cycle 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.
