We felt that this would be the best approach, as it is practical and hands on. Our advice is to begin with the frst and easiest of these projects and then work your way through all of them. This will ensure you will cover all of what you need to know to get started.Denise Palmer, Marketing DirectorIssue number 109Date of issue; 15/7/11Welcome to...... ...and the exciting worldof br ush pl at i ngThi s manual i s t he pr oduct of over t went y year s of our exper i ence and exper t i se i n t he f i el d of el ect r opl at i ng.

It will help you to familiarise yourself with the most important items in your kit, giving you the practical knowledge to get started on the frst plating projects, which are introduced later in this manual.The Power Plating RectiferMain features;compact and lightweight -used as easily for on-site jobs as in your workshop.Variable voltage (from 3v to 15v), max 25 amps - youre in full control of the power level, letting you tackle the smallest to the largest of jobs with confdence.Safety - the overload and radio frequency interference protection means you can use the rectifer in any environment.Digital display (volts and amps) Power indicatorVoltage adjustment (3v - 15v, max 25 amps)Output socket - negativeOutput socket - positiveOn/Off switchFRONT VIEWBACK VIEWPower inputsocketCooling fan intake grilleThe electrodes, swabs and leadsMain features;The electrode handles have been spe-cially designed to be comfortable to hold in the hand. Because the electrodes are made from top quality materials, they plate excel-lently, are hard-wearing and present no risk of contamination.The swabs have been specifcally designed to hold the plating solution effciently and to be re-usable. Once you have fnished plating, you simply rinse them out in tap water and allow them to dry. SwabElectrodeHandleRed lead (this end to be plugged into red socket on rectifer)This end of red lead plugs into end of electrode handleBlack lead with crocodile clip grips work to be platedThis end of black lead plugs into black socket on rectiferLarge electrode with swab and leadMain featuresThis electrode is much broader and fatter than the normal elec-trodes and allows you to proc-ess large, fat areas more even-ly and quickly. This electrode should only be used for plating very thin, or fash, layers of gold and not for normal gold plating.Electrode3The Pen Plating KitMain features;The pen plating rectifer is ideal for supplying power for smaller, precision plating jobs. The digital display is brightly lit and clear and the red and black leads plug into the red and black sockets on the front, similar to the Power Plating Rectifer. The other end of the red leads plug into the ends of the plating pens.The mini contact probe connects to one end of the black lead, while the other end of the lead plugs into the black socket on the rectifer. By touching the end of the contact probe to the surface of your work, you complete the electric circuit and plating takes place.The clear perspex stand provides a handy docking area to keep your plating pens organised.The plating pens come with two types of tips. Use the felt tips for rough surfaces and spot repairs where precision is impor-tant. The cotton tips deposit a solid layer of plate quickly and effciently.This end of red lead plugged into end of plating penPlating pens and perspex stand (design unique to Spa Plating)Ultrasonic cleanerFront viewBack viewBack-lit digital displayKnob for controlling voltageThis end of black lead plugged into end of mini contact probeRed leads (positive) stacked and plugged into red socketThis end of black lead (negative) plugged into black socketPower lead plugged into socketOn/Off switch Technical data about rectiferDigital display (counts down time of cleanin seconds)Conductivity testerSet button (controls length of cleaning time)Main features;Effcient cleaning - this piece of equipment is very useful for cleaning smaller, delicate items that have areas that are more diffcult to get at, such as jewellery and cutlery.Sonic action - it works by bombarding the object with air bubbles and ultrasonic, which dissolve the dirt into the water.Variable settings - you can control the intensity of clean by varying the time, from 90 - 480 seconds. Main features;Time saver - this is used to test whether the surface you want to plate is conductive or not. Sometimes metal can be fnished with a thin, invisible layer of lacquer to stop corrosion. If you dont know its there, it could mean you waste a lot of time trying to plate something, when it cant be plated.Multi-functional - not only can the tester be used to establish conductivity, it can also be used for diagnostic tests on your electrodes, leads and rectifer.Power inputsocket4SOLUTIONS AND POLISHESAll of Spa Platings solutions have been specifcally developed for the process of brush plating. Over the past twenty years, we have concentrated our efforts into researching and developing formu-lations that offer optimal performance especially for this process.Polishes and solutions used for the preparation of metal surfaces for platingIt is perfectly possible to replace the electrocleaning and ac-tivating stage with MPU, when preparing nickel containing alloys such as stainless steel.Cleaner - this solution is a very effective de-greaser and also removes the oxide layers which build up on metals, such as silver and copper.Activator - this is particularly useful for removing the strong oxide
