The CD mandrill is used to hold the stud within your CD studwelding handtool.

People have different names... Collets is a common one, so it's chucks you'll hear mostly. Chucks are the most common used terms, but you might also hear:

1. Mandrills
2. Collars
3. Arbours
4. Stud Holder
5. Discharge collars
6. CD Chuck
7. Chuck Collet
8. Chuck CD

All these terms are used to describe the (usually soft copper) holder inside the hand tool, essential for maintaining good quality welds. We will explain how to keep good quality welds in the video below

Ok the crucial thing is to set up the Chuck correctly. Right? the best way to ensure good collet life is as follows. You have to have a 1 millimeter gap from the front of the mandrill to the back of the flange. The easiest way to set it up is to have the stud sticking all the way out. You back off the back stop. Press the third all the way in and then move it out. So you've got 1 millimeter . That will give you the correct protrusion and the correct spring pressure to ensure satisfactory world.

Now you'll notice the little rubber rings, the little rubber rings are there to keep the whole thing tight. If the weld collet or the cd chuck gets loose and the stud falls out, you're going to have a lot of issues with poor welds. This can happen when the operator removes the hand tool off the stud at an angle. What happens is. The lines on the collet, on the chuck open out and they stud becomes loose. What then happens is arcing will appear inside the collet. This is where you lose energy, you get a bad weld. And this will burn out virtually straight away. You can tighten them up, by squeezing them in with a pair of pliers.

So if you just had one of the team know the diameter of the stud using maybe the application and the sheet of metal that you are also using. We can determine the type of stud that's most ideal for your job. But in terms of the chucks, the collars, the arbors, we just need to know the diameter. So say, for example, here we've got Capacitor discharge (CD) M5 stud you're going to need an M5 Chuck. So each diameter stud has a matching chuck. The only time you need to change your arbour is when you change in the diameter of your stud.

An example of a chuck. You can see it's a lot wider. Give yourself 1 mil and tie it up. That goes straight into your hand tool and away you go. You ready to weld to make.

The CD collet, the chucks, the arbors, the mandarins are consumables. They do burn out. You must ensure that you replace them on a regular basis to ensure a good quality weld. If you want to learn more about it, there's other videos on our website, which is www.studfast-studwelding.com, where you can interact with us. Ask us any other questions you might have, and we'll be on to them straight away.

Some commons problems with chucks cd can be not securing the chuck nut in the gun. If you find, the chuck collet just keeps coming out of the gun then there is no power in the weld.

Some customers have got in touch with us to say the chuck collet looks like it is threaded inside. We will always send a free chuck nut key when you buy a new machine from Studfast Studwelding. In order to rectify this problem you will require a chuck securing key to tighten up the nut and this will secure your chuck and prevent it from falling out. The weld will not go through unless the chuck is secure as has to complete the connection.
