CIG Transtig 150 TIG Welder

The Cigweld Transtig 150 is an AC DC Tig Welding Machine that is based on a transformer, the old school type unlike the modern inverter welding machines. AC DC Tig Welding or DC TIG welding is achieved by swapping the orange leads polarity by either allowing them to go straight through or criss cross each other.

The welder can handle the following duty cycles. 60 Amps at 100%, 120 Amps at 25%, 150 Amps at 17%. Duty cycle is calculated at % of time in a ten minute repeating period. 100% weld all day at that setting, 70% weld for 7 minutes at that setting then rest for 3 minutes, 40% weld for 4 minutes rest for 6 minutes etc.So at 120 Amps, the welder could run for 150 seconds, rest for 450 seconds then repeat.

Straight off the trusty trailer. It weighs about 90 kilos.

This gives me pleasure. Involving kids in the active participation of pulling stuff apart. Alek(6) is turning into me ever so slowly. He just needs to grow taller and lose his hair.

The ratchet was too boring, apprentice needs some action. In comes the power assisted ratchet.

No mouse wheels in here, just hard core copper with a lot of electrical things.

A close up the heatsinks reveals a lot of built up dust. I quick blow out with the compressor and we are clean.

This is the electronic control board that sits behind the front panel. It was clean as it is sealed in it’s own box.

Finished with the clean up. The front panel has pre and post gas control timers, Current selector, arc force selector, TIG or manual ARC switch. The AC / DC is selected by crossing over the orange leads.

Alek and Marcus(4) pleased with the result. They then set about like a couple of raptors insisting I power it up and start welding. Look at ’em, anyone would think it was theirs the way they pose.

Here is a shot of the foot controller and TIG gun. The foot controller also varies the current.

Here is a shot of the unit with the argon attached. The power source is clean and shiny. Almost like new.

Spare collets, electrodes, gas shrouds and a “feed wire holder” on the right.

Here is the manual arc electrode holder. Note the small hand held push button.

Welding Stainless Steel   by Vito Garza

There are such a lot of different grades that things are made of and it is not necessarily clear which one you are about to weld.

There are ways of telling, like spark testing but I have yet to see anyone that could tell one type of iron casting from another by spark testing.

Come visit us right here for more Welder and Welding Info and get two Welding Ebooks Tig Welding Stainless Steel.

Think about this for a minute…Tool steels contain around one % carbon and are thought to be difficult to weld because of excessive toughening and even cracking problems.

It turns into graphite and that actually serves a purpose as a lubricator on cylinder walls of a combustion engine.

But for welding, all that carbon and graphite is hideous. Carbon in those percentages cause toughening of the weld metal and surrounding heat area affected. To make things worse, cast iron is very brittle.

But tests have shown that for tig welding cast iron, aluminum Bronze is a very good choice.

Lets look at why…


2. The solidifying weld metal does not have high shrinkage stresses to cause the metal to break next to welded areas.

3. Aluminum bronze tig welding rods are virtually as powerful as steel

4. When welded on A/C, these Al bronze tig welding rods flow and wet easily and achieve a minimum amount of dilution from the cast-iron base metal. That’s usually a good thing.

5. Aluminum bronze tig welding rods are much cheaper than nickel rods.

A good tip for using this rod on welding iron castings is to set the gtaw machine on A/C just like you would weld aluminum. That may let the bronze filler metal flow without mixing too a lot of the iron and carbon into the weld.

Gasless Mig Welders – What Are They?   by Vova Finkelshteyn

One of the things you learn for those who have a small Miller Dynasty 200 a/c d/c inverter Tig welder is tips on how to do welding on dense aluminum castings with much less amperage. I have had the opportunity to weld with a few really popular Tig welding inverters that can handle Tig welding aluminum utilizing 115v or 230v vitality; the Miller Dynasty 200dx and also the Lincoln Invertec v205t. Both machines are good quality power sources but those two welding machines are restricted to around 200 amps expenditure. Being limited to 200 amps enables you to weld smarter not sexier. Instead of just positioning the amperage to 275 and plowing ahead as you would on a challenging Tig Welding Machine, you’ll have to use your head. Preheating thick aluminum parts is actually a proven way to slow up the amperage required to weld. But when you have been in your garage and do not need a heat treat heater or oxy-fuel torch, how will you preheat? Well, here can be a few tricks I have learned:

Use a gas bbq. But make sure the aluminum part to generally be welded does not contain anything harmful that may be taint the burgers you might like to cook next week. (It would actually be recommended that you have a cheap smoker dedicated for preheating light weight aluminum parts)

Wrap the part on aluminum foil and put it on the stove on medium heat until the heat conducts through typically the part. (About one or a couple of beers later the part will be warm enough to weld)

Use a smaller propane torch and keep it moving till the part is hot plenty of. (Just hot enough to sizzle spit need to be ok. )

Another tip for reducing the amperage needs to Tig weld aluminum is to apply a 50/50 or 80/20 argon/helium petrol mix. The added helium really is important. Not only will you would like less amperage, but a aluminum will puddle quicker and cleaner than with the help of pure argon. Trust me for this one!

Lastly, I recommend using since small a Tig cup as they can be. Some people refer with them as Tig welding nozzles but whatever the case it is the ceramic tip that moves on the end of that Tig torch that markets the shielding gas on the weld and protects a tungsten electrode from simply being oxidized. Using a small-scale Tig cup requires significantly less shielding gas. For example a #7 cup might require 15-20 cfh whereas a #4 cup only will require 8-10 cfh. That much less gas blowing for the part makes a significant difference in the amperage important. In addition to the following, the arc energy that is dissipated through cathodic etching (also called cleaning action) will go where there might be gas shielding so you can find extra arc energy offered to be focused at the particular weld puddle.

I reminded myself of most these tips just yesterday when I welded your 4 inch machined ingot of 6061 aluminum with a Miller Dynasty 200 amp Tig welding inverter. I needed to replace some material that had been miscut by a machine shop on the prototype part that already had lots of machining time invested.

The various helpful tools provided through Tool Room Services    by R Sheth

Building the structure of metal by cutting, bending, and assembling the raw metal is called Metal Fabrication. The cutting of metal during fabrication is done by saw, shear, or chisel; torching is done with handheld torches like oxy-fuel torches or plasma torches. The bending is done using hammering, press brakes and similar type tools. The assembling that is joining of the metal pieces is done using welding, threaded fasteners, adhesives and riveting.

Scope of Metal Fabrication:

* The work done by blacksmith is also included in fabrication.
* The products produced by welders involve the use of fabrication.
* The making of boilers also requires the skilled use of fabrication techniques.
* Steel erectors/ironworkers, are also involved in metal fabrication jobs.

Raw materials

The standard raw materials used by metal fabricators are plate metal, sheet metal, tube stock, welding wire, hardware, CDSM, square stock, sectional metals, castings and fittings.


Many fabrication shops have speciality processes which they develop or invest in, based on their customers
