A dc series motor can work on dc and ac because dc motors are totally reversible.
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.

It can, but if you're wanting to run a 120v light bulb on DC, you'll need 120v DC to get the rated output. That's a lot of batteries. It's easier, and more sensible, to find a DC rated light bulb, such as an RV bulb.
Both are shielded metal welders but differ in the electricity they use. Ac welders can weld heavier metal while dc welders are better for thinner metals. Ac welders can weld magnetized metals. Dc welders can not. The arc in an ac welder is harder to control because of the pulsating current. Dc welders are more expensive. Some welding machines offer both options.
GMAW welders work in production shops.
I am not sure that it is more common. The large welding rigs that are mounted on trucks mostly use DC, but they can be set for AC. If the question is based on a survey of the cheap welders at a retail outlet, the answer would be that AC welders are simpler to make, since only a transformer is required to change the voltage. A DC welder needs to convert the power from AC to DC, which is more complicated and therefore more expensive. Cheap welders may be easier to sell to a beginner, therefore more of the welders would be AC.
DC WELDING:We gain a smoother welding because of constant and linear direction of current.The arc will be more stable and easier to handle.DC welder can use both AC and DC welding rods.AC WELDING:The arc is not stable here and needs to be stuck again because of the fluctuating nature of AC.It is not as smooch as DC welding.These welders cost less when compared to DC welders.
The difference in the ac/ dc , or polarity of welding rods is in the makeup of the flux coating , or the alloy of the metal, and in the case of SMAW ( Shielded metal arc welding ) rods , which have a flux coating, are usually marked on the base of the rod.
Welders in Manitoba earn an average of $22 an hour. This varies depending on experience and who they work for.
The 6013 Rod can be used on either ac or dc arc welders, at around 90-120 amps depending on your settingsTucson Direct
Welders earn between 20 and 30 dollars an hour. This depends on experience and whether they have their own business or not. Welders also usually have the opportunity to work overtime.
You can try TRUREMOTE, they work for a wide range of lincoln engine driven welders, we have 14 305G model welders with the remotes attached, and consider them a huge asset.

Steelworkers and welders
Welders make between 40,000 and $51,000 per year. Salaries for experienced welders range from $50,000 to $67,000. Welders can also make overtime which adds to their pay.
