Hello Shawn, I have been welding as an engineer for around 50 + years. My favourite method is oxy/acet for very fine work, however for everyday convenience I use a gasless mig welder no problem, or if I really need to lay it on I use the Oxford in house, or the switchmode Kemppi 151 if the h&s...
Hello Mini, if the transformer is semi sealed,i.e. covered with insulation/tape etc, is there a slight bulge on one side of the transformer?, if so it is probably a thermal fuse. If you very,very carefully cut/strip the covering away it will reveal a small plastic block with a wire at each end...
Ali' versus copper
There is no contest, ali will lose everytime electrically. They make cheap heatsinks if big enough, but poor conductors no matter how big. Try to find 2 pieces of wire i.e. 1.5 mm, 1 made of copper 1 of ali'. Connect to a power supply and screw up the current, the copper wire...
If ignition timing is near enough correct, and you are getting a decent spark at the plug, then it should run, otherwise try a squirt of "Easy Start" down the carb' if it does'nt fire up you really do have problems. Get back to me if you need more help, Bob.
There is so much non info' made available to end users by the manufactures about transformers it makes me laugh. Its probably the next biggest con' to beauty products.
I.e take a tiny transformer used to charge your mobile phone,(around 4.5 to 6.0 volt at 200 M.a.) Strip the outer, low voltage...
ALI verses copper
take 3mm of copper wire and shove enough current through it to melt it, try the same with aluminium and then try and tell me theres no difference. I remember watching the pool of ali' running out the bottom of a 24 volt starter charger seconds before the main fuse ruptured on...
To all those who noted the mistake imperial verses metric, it makes no real difference other than cost and speed of rust removal. I have stated that it is a very aggressive remover of rusty or good metal as opposed to soda. If you want to try it out without any hassle first. Put a tablespoon...
Carbon Arc brazing unit
Hello Mike, a couple of not very good pics (my son has my proper camera). You are free to publish/copy or do as you please with them as you requested. I do not have M$ outlook so could not send to the site you listed, kind regards, Bob (deltabravo).
Carbon Arc brazing
Hi all, I own a carbon arc brazer which I use for all manner of brazing. I made the transformer out of an old 35 amp welder. I unwound the secondary coil and tapped it off at 4 different places to get a variable current choice,I also fitted a fan to it. It works fine for me...
Hello fellow members, this ancient retiree offers those who will observe the time /mixture/current limits, a very, very, easy way to remove rust on steel and iron parts. Parts required are-: 5 amp minimum power supply at 12 to 24 volts D.C. i.e. battery, or charger.
1 cupfull of household salt...
FAN for welder?
I was just browsing the forum and came upon this entry. If you need to fit a fan on one of these machines, my advice is, guess what you need and double it! you can never under cool a psu on a welder, thats why Oxfords are so succesful and reliable even after years of abuse. A...
Need a Lock ?
Hello again, like I said in my last post, go to poundland, at least you know the cost. As for all the other 'hi tech' locks ? do you know of any that I cannot cut through with a 12volt grinder I made using a cheapo' motor from a kids model car? Easy, just attach a 1 mm thick x...
I am of the opinion that if the health and safety brigade and been around a 100 years ago we would still be rubbing sticks together to get a fire started today. There would'nt be any gas or electricity available too dangerous, all dwellings would be ground floor only (can't climb stairs without...
Hello, just go to your local welding supplier and ask him for a carbon brazing attachment, it looks a bit like a set of spot welding arms. There are two carbon electrodes that when attached to the welder makes an arc that you feed a flux coated brazing rod into whilst touching the part to be...
Hello Simon, as a retired engineer I reckon Aeros advice is sound enough, in fact that is what I would do if a friend made the same unforgivable? mistake you did. Diesels do not like petrol being dumped in them, the seals in the pump and the fact that they are very high compression engines does...
Hello Future Jack, forget the locks and chains, they cost a fortune and are easily cut by the welder you want to protect. Go to poundland or your local hobbyshop and buy a p.i.r. operated sounder and fit it to the shed. There are some really cheap, very loud, units around nowadays, with a coded...
Hello, you should really be using oxy-acet' for a car in that condition, considering you say you are a novice. Mig or stick welding is fine when you have a bit more experience under your belt. I know how hard it is to try not to blow away the welds when you are learning the trade, I remember how...
wiring up the Oxford
Hello, connect the mains as follows-: Neutral=0, Live=any of the terminals marked 400+volts (preferably the lowest number), Earth as shown on welder. Use a seperate 25 Amp mcb (circuit breaker) for the mains supply, and wire it to the elcb side of the fusebox if one is...
