While mig welding I personally use 10 or 11, but it depends on the individual. You want it dark enough (higher no. darker) to protect your eyes from flash burn but light enough to see the weld. Start at the highest setting and go lighter until you can see good enough. No lighter than necessary. I hope this helps you out.

The generator does not operate in accordance with the specified technical conditions, such as too high stator voltage, iron loss increases; if the load current is too large, the copper loss of the stator winding increases; if the frequency is too low, the cooling fan speed becomes slow, affecting the heat dissipation of generator; the power factor is too low, so that the rotor excitation current increases, resulting in the rotor heating. Check whether the indication of monitoring instrument is normal. If it is abnormal, necessary adjustment and treatment must be carried out to operate the generator in accordance with the specified technical conditions.

Exhaust black smoke
The main causes of exhaust pipe blackening are less air in the cylinder, more fuel, incomplete or untimely combustion of fuel. Therefore, when checking and analyzing faults, look closely around this point to find out reasons. Check cylinder by using the method of oil cut, the first distinction is that the individual cylinder is not working well or all cylinders are not working well. If the black smoke disappears when a cylinder stops working, then the black smoke is caused by the bad work of individual cylinders. The reasons can be found from the bad work of individual cylinders.

The main reasons are:

A. Poor nozzle operation

The injection pressure of the injector is too low, the nozzle drips oil, the spray quality is not good and the oil droplet is too strong, all of which will cause the diesel fuel to burn incompletely. Therefore, in the detection of diesel engine cylinder knocking sound, exhaust sound uneven, that is, fuel injection problems, should be immediately checked and adjusted injection nozzle.

B. The fuel injection pump adjusts the tooth rod or the adjustment rod stroke is too large, resulting in too much fuel supply.

C. Valve clearance does not meet requirements, resulting in insufficient air intake.

D. The contact surface between the plunger sleeve of the injection pump and the valve seat is not sealed, or the locking screw of the regulating ring of the fuel injection pump or the loosening of the plunger adjusting arm cause the imbalance of the fuel supply and lead to intermittent black smoke emission.

Do normal maintenance first, like oil, oil filter and air filter and then let it firts warm up before applying a load.

If the saw is brushless the a Trailing Edge light dimmer is required to avoid hunting.
It is not recommended but wire as you would a light dimmer.

You have posed a very vague question with no details about the application and have even omitted to tell us whether you have a generator set or whether you have the alternator and wish to build your own generator set?

In the case of a generator set the requirements and precautions will be found in the owner's instruction handbook.

There isn't much you can do with servicing the generator set or transfer switch unless you've got lots of experience in diagnoising semi-conductors and electronic components.

Depending on the age of the system, it would be benificial to have a qualified service tech take a look at it.

As an electrician, I've installed several back up generator sets in homes for customers and have had a few of these automatic transfer switches with intermittent operation issues. Sometimes it's the switch and other times it's the Generator that is causing the problems.

Hope this helps, and best regards!

Does your generator is single phase generator set or three phase four wire generator? Why your generator set is 110V at full load, it should be 220V or 240V to generator electricity. If it is used for industrial equipment, it should be 380V, 400V, 440V, etc.

Check all fuses.

Try the lamp test and make sure all panel lamps light.

Check battery voltage is 12.3VDC or greater.
