What settings do i use to arc weld.


Not sure what machine you have, but it should be DC straight (electrode negative or DCEN) and DC reverse (electrode positive or DCEP). The polarities have different characteristics. For example, if you're planning to TIG weld, you would either use DCEN or AC (if welding aluminum). For the general stick welding process, DCEP tends to give you a deeper weld. The welding rod you buy will have recommended machine polarity and amperage range settings, you should use the recommended polarity for whichever rod you're using because different rods are designed to weld under different circumstances. But, generally speaking, most welding rods for steel will work on DCEP without much trouble.

How do I remove electrical interference on my dvd recorder?


Hi David
You need to figure out how the interference is getting inside.
Look at the external connections.
HDMI Cable or Perhaps the Power Connector.
Noise from the power cable would be most likely.
A Ferrite Bead can often be clipped onto power lead to dampen electrical noise. Electronics supply stores have these.
If an AC to DC external box is used. What is the required DC input to your DVD ?
For example if the AC is dropped to 12v DC and then plugged into player via a small connector. You could get your own connector and supply from a 12v vehicle battery. Be careful to maintain correct polarity to tip of connector.
Use a cheap multimeter to check voltage & polarity.
Substitution....This would prove that the noise source is from the Power Supply.
Cheers

What voltage and polarity do the ACS-5 speakers require?


Computers always use DC voltage. Computer speakers receive DC voltage from the computer.
DC voltage has a Positive and Negative polarity.

In the power jack of the speaker, the Center pin is the Positive connection. The outer shell is the Negative connection.

Center hole of the DC adapter plug - Positive.
Outer shell of the DC adapter plug - Negative

Voltage 5 Volts DC.

Dear Sir/ Madam, I have TWO Western Digital USB


first of all , you are looking at the wrong voltages. The important voltage is the DC OUTPUT, which is the voltage the external harddrives use AND the polarity of the plug attached to the harddrive end of the cable.
if both the harddrives have say 12v dc output and both have the insignia of the center conductor being + (posative) then you can interchange them. and you CAN run a 9volt unit with 12volt DC power, but not the other way around.
Look at your power adaptors again for the OUTPUT and polarity.
should be a half-circle with lines depicting the polarity(+,-) of the center and sheild connections to the hard drives printed on both the harddrives and the power adaptors . This can also be tested with a dc volt meter while the adaptors are plugged into the wall.
DO NOT try to test the AC end while plugged in!!
Regards

I just bought a AC225 stick welder, there are two cables coming out of the machine, I don't know which one is the work cable and which one is the holder cable?


it doesn't matter which one you use because it's alternating current, normally the longer one is your electrode holder cable so you have more cable to move around with,but either way it will work, if it's a D.C. welder then all your doing is using reverse polarity and in some cases welding this type of welding is superior to straight polarity

BEFSR41 power supply?


Both the voltage and the polarity should be printed on the case of the router. The polarity should be right next to where the power plugs in.

The polarity information will look something like this:
--(-(+))--

If you take the router into a local Radio Shack, the clerk will probably be able to tell you which power supply you need.
