Here are some more information for Electrode Holder:
When you see the letters AC/DC on your welder, do you think of one of your favorite rock and roll bands? Seriously though, the difference is quite important to the final quality of your welds.
AC (Alternating Current) and DC (Direct Current) is used to describe the polarity of the electric current that the welder generates and in what direction it travels. If you use the wrong polarity for a certain welding rod, your weld strength will not be very good.
The general terms associated with polarity are reverse polarity and straight polarity. These are common to the welding trade. Another way to describe the two terms are electrode positive and electrode negative. Electrode positive is the same as reverse polarity. Electrode negative is the same as straight polarity. Hence the + and the - written on your welder where the cables connect to it.
Any type of welding rod you buy will be labeled as to what polarity should be used for welding with it. Using the correct polarity will ensure the proper penetration and the over all look of the final bead.
If you use the wrong polarity you can tell by the signs. There will be an excessive amount of spatter, you will have bad penetration, and you will have less control of your arc.
Some welding machines have a switch to adjust the polarity. If your welder doesn't have one you will need to switch the welding cables around where they plug into the machine. If you want reverse polarity, you need to make sure the electrode holder is plugged into the + terminal.
The easiest way to tell if you are using the wrong polarity is by the sound and the feel of the weld you are laying down. If you don't have much experience with stick welding you will have a little more trouble determining the difference. I have seen guys weld all day long with the wrong polarity. Then I would grab their welder to use for couple of minutes and I could tell right away. It all comes down to experience.
If you don't have much experience stick welding, you will need to double check the way the machine is set up. Follow what the welding rod package tells you to do and do it. If you are using 7018 rods, you will want to make sure it is set up for reverse polarity. Also visit http://weldwithavengeance.com/ for many more welding tips and tricks.

Cefaly – A Novel design Electrotherapy Device for Prevention and Treatment of Headache
About Cefaly Treatment
Cefaly is the first cranial analgesic electrotherapy device to have advanced Transcutaneous Electrical Nerve Stimulation treatment and an ISO medical certification. Cefaly can also help people experiencing painful discomfort of trigeminal neuralgia and frontal sinusitis.
Headache are not specific to a particular age group but a more generalized problem. Cefaly is known to acts on the physiological mechanisms that are not age reliant. Therefore, Cefaly aids in alleviating symptoms and preventing them regardless of your age. Moreover, Cefaly is suitable for children also from age 8 and above, provided it is used under adult supervision.
Cefaly employs sophisticated state of art technology using Transcutaneous Electrical Nerve Stimulation therapy in a patented device that is lightweight, easy to use and effective.
Cefaly creates gentle electric impulses that act on the nerve cells. It works on nerves responsible for the pain and various other sensations in the area that is most associated with migraine and headache.
Cefaly is beneficial, when the pain is located in the front half or the skull. Through its skin electrode, Cefaly transmits detailed electrical impulses intended to manipulate the trigeminal nerve utilizing Transcutaneous Electrical Nerve Stimulation to prevent pain signals from being realized in the brain and thus hampering the stimulation of endogenous endorphin production.
Worn like a pair of spectacles, Cefaly is designed to prevent and treat chronic and recurrent headache and substantially reduce or prevent stress and stress related anxiety. During the 20 minute Cefaly treatment session, a pleasant tingling sensation is felt. The intensity of the sensation can be adjusted to personal preferences. The treatment can be repeated immediately, if required. However, there are no known benefits when the pain is located at the back of the skull or in the lower part of the face below the eyes.
Cefaly should not be used:
• After a recent brain or facial trauma
• If suffering from Meniere's disease
• If having broken or damaged skin on the forehead, in the area of electrode application
• While driving or operating heavy industrial machinery
Why Cefaly?
Cefaly utilizes Transcutaneous Electrical Nerve Stimulation therapy and is well recognized for its efficacy, safety and absence of side effects. It is not only harmless but very safe to use. Its safety standards have been demonstrated in tests as well as in clinical studies. No adverse side effects were evident during clinical trials.
Cefaly generates very precise electrical impulses which stimulate the nerve fibres selectively. As the impulses are generated very gradually, they are barely visible at the start of the treatment session. Because of advanced technology, Cefaly enables the electronic feedback mechanism to adjust the electrical impulses to specific requirements tailored for efficacy and comfort.
Cefaly user statistics reveal that:
• 95% of users find Cefaly very simple to use
• 87% of users describe a definite improvement
• 79% of users saw a drastic reduction in their consumption of drugs
• 2 out of 3 tension headache are relieved with the use of Cefaly
• 65% reduction in headache with only 20 minutes of Cefaly use
• 66% reduction in severe pain after only 20 – 40 minutes of Cefaly use
• 59% reduction in recurrence and duration of painful headache
• 1 in 4 migraine attacks are controlled by Cefaly use
Cefaly Technical Guide
Cefaly is supplied with:
• A carry case
• Fitted batteries (2 x 1.5V AAA alkaline batteries)
• Skin electrode
• Cleansing wipes
• Easy to follow User Manual
Use of Cefaly is uncomplicated to easy. It is worn like a pair of spectacles or a forehead band. Its technical guide includes:
• Firstly place the self adhesive reusable Cefaly electrode on the forehead.
• Then the Cefaly unit is positioned over the electrode to form an electrical connection.
• The button on the device is pressed and Cefaly starts delivering the 20 minute treatment automatically. For the extent of the treatment, the individual can either relax or carry on with the task in hand.
• But use of Cefaly is prohibited while driving.
• When the treatment is concluded, Cefaly unit is first removed from your forehead, followed by the skin electrode.
• During the session, a pleasant tingling sensation may be felt and the intensity of the sensation can be adjusted to suit personal preferences.
• After the completion of one treatment session, Cefaly and the electrode can be stored away in its holder or another session can be started immediately, if needed.
• After conclusion of the session, a localized tickling sensation may be felt on the forehead.
• This pleasant sensation of lightness and coolness may be felt all over the forehead and may extend to the whole of face, lasting for several hours at a stretch.
• On the other hand, a deep feeling of rest and relaxation is felt with this anti-stress effect and a very strong sense of wellbeing envelopes the body.
• Cefaly treatment is found to be the most viable way of increasing the production of endorphins naturally, giving the individual a profound sense of general wellbeing.

electrical, electrode holder & earthing diagram for arc welding?
electrical wiring diagram and the distace placement of earthing clamp from arc for better welding result
Simple circuit. AC, DC+ and DC-. 100 to 150 Amps use 0 cable out to the first 200 ft and drop to a comfortable gage at the stinger end with a whip of maybe 20 feet will give favorable performance with no noticeable drop in amperage. The most important area to be careful of is the splice ground clamp and stinger connections.
