This welder welds just about anything you can think of. The inspiration for buying it was the irritation of having everything welded elsewhere by someone else, and of course the price of the work done. For some reason I get more and more things to weld together than ever before, it comes and it goes, so don't think this is what I do all the time.

The guy who did my welding before asked me if I could build him a rotation table that has a constant rotation speed. The idea is if you weld a round item that it turns through 360 degrees while you weld it non stop. It saves time and you don't have to stop/start the weld all the time. They had a wiper motor with a chain drive turn table, but it was a real backyard job and the speed control was really rough. If the mains changed (like when you weld) the motor speed changed also.

Very early on I discovered it's not so easy to hand feed the thin welding rods into the welding area. While one can probably learn to do the feeding constantly, I was thinking of a better way to do this. The rods are also usually up before the weld is finished and there are always short pieces left you cannot do much with. Now if you know me, I'm lazy, I don't want to get up every minute to get a new welding rod... so a cintinuous feeder was important - and this is what I came up with.

Oh yes, when I ordered the machine, the manufacturer was nice enough to add a 'low range' switch as well. I have welded sheet metal parts down to 0.2mm together.

I appologise for all the stuff around cluttering the table some, there are usually time to use stuff, but not enough time to put everything away, so in many cases the temporary kind of becomes permanent. You should be able to see the rotating disk and the basic structure to hold the lot together. Really simple, I used 38mm square tubing and welded it together with you-know-what.

What you see here is the turn table disk on top, a plumber block to carry the weight and a stepper motor with a 50:1 gearbox. The earth clamp of the machine clamps on the rotation shaft (30mm) so that the welding current does not pass through the bearings or the stepper motor's bearings.

This is a swivel arm rest I added. The arm rest also has a few slots in it so you can hang the torch in it as you see there. I made the hinges with caps (short pieces of pipe) with bearings in them. The arm rest can be adjusted up and down as well and the pin you see there is the stopper. The inside pipe has a series of holes where the pin goes through. I did try to motorise it as well to make it a bit fancy, but this didn't work out too well. The electronics worked ok, but the threaded rod and nut I used as well as the connection to the motor part wasn't up to scratch, so I decided to leave the heigh adjustment as you see there. There is a small neo magnet to hold the arm folded as you see, otherwise the arm rest tends to swing around a bit.

This is the electronics control box. The big transformer is to supply 80V to the Gecko drive driving the stepper motor as well as 12V for the wire feeder(s). The PCB you see above the transformer has a 16F684 pic that does the speed control and direction of the stepper motor. There is also a digital meter indicating the speed setting for the turntable. Needless to say the speed is absolutely constant and is set with a pot.

The two boards on the left is the wire feeder control(s). I was going to put in two wire feeders, one for stainless and one for steel (ferrous) wire, but haven't finished the second wire feeder yet. I will one day. No really... These boards both have pic 16F684's that control two relays each for the wire feeder motor's direction as well as PWM to a FET that does the speed control, also adjustable with a pot.

What you see just above the reel of stainless wire is the wire feeder and a spiral tube leading to a hand set. This spiral tube is a standard off the shelf item used for welders.

and this is the hand set. The hand set is a PE round bar with a slot through it where the spiral tube runs through. Also in the handle I milled cavities for tactile switches, the foreward one is for feeding the wire out, and the less foreward one is for reeling the wire back in. You cannot see the switches because of the black crimp sleeving over it.

Here you can see the steel wire coming off the reel, through the 'feeder block', into the spiral tube and it comes out the hand set as you saw in the previous picture. Thr drive mechanism feeding the wire is fairly simple. It consists of two bearings, the groove formed by the two bearings keeps the wire guided through the same place, on the other side of the wire is the nissan wiper motor shaft and it is only the pressure of the shaft on the wire that feeds it.

If you look carefully you will see a black Ertalite block with some steps cut in it. The work of this block is also to feed the wire through, hold the spiral tube's end (you can see the small clamp screw on the left of the block) and lastly but very important, the block supports the motor's shaft. Wiper motors cannot carry much load on their shafts, they are strong and faithfull turners though. The center step cut in the block is an 8 x 8mm slot and the wiper motor shaft snugly fits in there. Any side pressure from the bearings, which is the tentioner side, gets taken up by the block and not the wiper motor bushes. You can see a support plate welded in place behind the Ertalite block.

The thin red, pink and green wires goes to the tactile switches and a silicone sleeve covers the lot. The bottom red and green wires is the wiper motor's. One day I may decide to make it neater also. One day a LOT of things will be done around here.

A closer view. The bottom cap screw is the hinge, and just left of the red.... something... you can see the tensioner cap screw.

Once the feeder speed is set, you can weld continuously and non stop any length of weld you want to make.

Some of the welds made, this is a small 25mm weld in 1.6mm rectangular tubing onto a 12mm hollow tube (pipe). I just grabbed one to take the picture.

and this is a bit heavier weld job, one of the 16kg anchors I made for the boat from 10mm iron sheet. I have to date welded hundreds of welds and on a veriety of things.

Finally the argon gas. This is a pure gas that pushes the air away thus prevents corrosion. Any corrosion can only be from the outside, and not on the inside of the weld as is the case with the old transformer stick welding.
