The plasma cutting process has been around for more than 50 years starting during the World War II era. The war demanded a faster and more reliable way to improve aircraft development, thus the plasma cutter was born allowing a protective barrier of inert gas around an electric arc to protect the weld from oxidation.
Over the course of the next several years, the plasma cutting process has drastically developed with further testing and improvements. At this time, it was discovered that by restricting the opening through which the inert gas passed, the heat produced by the process was tremendously elevated. At the same time, the smaller opening caused the flow of gas to speed up dramatically, ultimately blowing out a channel in the work.
In the mid sixties, plasma arc cutters began seeing commercial use with everyday applications as the process became a bit more common even though it was still extremely expensive to carry out. Large factories were able to afford the advanced technology and thrived on the ability to cut metal quickly and more efficiently.
Over the years, plasma cutting has worked its way into manufacturing plants, shops, and even homes. As the manufacturing of the plasma cutter cost has been reduced by development of technology and the competition of many affordable units such as Longevity plasma cutters, the plasma cutter process is now widely available and affordable in comparison to the early days and has become a must have tool for the working individual seeking or needing to cut metal.
Currently, plasma cutters are dual voltage and there are units ranging from 20 to 400amps out on the market. With plasma cutting being such a powerful and efficient tool to cut metal, we are sure that a plasma cutter will not be replaced anytime soon and the technology advancement will only fine tune this already convenient technology.
If you don’t own a plasma cutter, now is the time to give it a shot. There are plenty of suppliers out there and do you research, but we currently recommend Longevity plasma cutters for the price and warranty period. Give them a try.

TIG Welding
Help answer the question about welding tig
If you can do mig welding can you more the likely do tig welding?My fiance has been doing "mig" welding for about 3 years now. He just got laid off and someone called him about a new position BUT they do "tig" welding, he isn't too sure what the difference is or if he is going to fail the test they give him for tig welding. Is there a big difference?

Im a Ybanez also nasa toronto Canada. coincedentally I also have an older brother named michael ybanez but he doesnt weld though. taga cebu po kami pero nasa toronto na ngayon
Sorry but this is nothing special in europ 80% of the TIG welders are welding this way ( cup walking ) And he can be more a big boy if he stards using thikker wire ,instead of the 2.4 mm he is using now for the filler’s, that’s for young boy’s!
Greetings Ray
Thanks bozzza – cheers to all those who share their experience and help others
The short answer is no.
There is not a massive amount of industry around the coastal areas of spain , and any welding work would really be centred around making Gates , Fences and Rejas ( Security Grilles ). If this is something that you are able to do then my advise would be to looking at starting this as your own business because you would struggle to find reasonably well paid work like this on a permanent legal contract here in Spain
Thanks for the reply! – funny your comment was removed – author, you should allow the sharing of knowledge..very sad.
Mig and TIG welding are all arc welding. TIG is arc welding in the presence of a tungsten electrode which is non-consumable and an inert gas and the welded material. This is usually used in the aircraft industry. MIG welding is still arc welding in the presence of argon and wire feed consumable. TIG is usually a better welding technique. These are different from stick arc welding which uses flux coated sticks in developing an arc.
When you talk about pulse tig it is mostly DC welding. You use the pulse to help reduce the distortion. It is mostly used on all ferrous metals. You do not need or have the pulse feature on AC for aluminum. You would need an AC or AC/DC machine for tig welding aluminum. They are some what costly. When tig welding you need to stay with the better name brand welders. Thermal arc, Hobart, Miller, and Lincoln are all good machines. To weld 1/4" aluminum you need approximately 200 or more amps. So this puts you into a machine that is in the $2000 range. Then you need a bottle of argon gas. If welding for any length of time at those amps you would need a water cooled torch. Not to mention the water cooler, foot pedal and all the other items needed. All these items are costly. I am not trying to discourage you but you need to know it is going to cost you some bucks to invest in all the equipment you will need. Good luck!

TIG welding typically produces a higher-quality seam than MIG welding. It is also generally easier to weld thin metal pieces using TIG instead of MIG.
The internal structure of the fuselage is generally (from what I recall), a mixture of welded and riveted structure with the skin riveted onto the structure. It would be far too time consuming to weld the skin onto the structure, not to mention the costs involved if a weld is done incorrectly. Until an effective method of mass-producing aircraft is developed (Eclipse tried it and has so far failed), the tried and true method will continue to be used.
You will weld in accordance to the weld procedures that will be given to you for the specific materials mentioned.
What you have to your advantage is being able to Oxygen- Acetylene weld. You need to be able to use both hands. One to manipulate the TIG Torch and the other hand to feed and dip the filler wire. Good Luck !
I beleive its called “Walking the cup” its just a easier way/more steady way of moving the tig torch rather then free handing it and being shaky.
It takes awhile to get use to,
and its just a accepeted method of pipe welding and is genrally used because it is consitant and usally creates nice looking welds that r sound
What's your question?
I was working for a company welding aircraft parts. APU assemblies for boeing, lear, and raytheon. I was recieving $18 and hour but would have been able to make more through raises and fringe benefits. i ended up quitting because they cut out all overtime. I need certs for all kinds of AL, S.S., And CrMo. I had to get tube, and plate from .020 to .375 certs before I even started welding on the parts and that took a couple of weeks….
I think a lot of people hear about guys making $40 an hour and think they can jump in on that but what they don't realize is those guys have been doing it for years and have recived annual raises etc.

Welds are probably huge by the way he’s slinging the tungsten around.

There is a big difference between MIG and TIG welding, in both the process, and the skill level required of the weldor. They really are two different processes altogether, and the MIG is the much easier of the two.
There is much to read on the web, including some great information at the Miller and Lincoln websites. They can give you a pretty great overview of TIG welding. But, as with many skills, it takes hands-on practice as well as study, to be successful.
If your fiance has ever welded with a gas torch, he might already have the skills he needs. Unlike a MIG welder, a TIG does not feed an electrified filler wire for you. You are in control of a separate heat source (the torch) that you must manipulate in order to melt the base metal together, while adding the filler by hand to the molten puddle you're creating. It's the same way a gas torch works, just with electricity, rather than gas, as the heat source.
The tricky part comes in learning how hot to make the puddle, how much heat to apply (with a foot or hand controller), and how to coordinate the filler at the same time. Quite often, TIG welding involves metals like aluminum or stainless, which have their own quirks that need to be considered. It's by no means impossible to learn all of this…and it can be a very valuable skill to have, often paying higher than MIG welding jobs.
If your fiance shows this prospective employer that he is a professional who takes pride in his work, has studied the subject, and is willing to learn, he may get his foot in the door and start down a new path on his welding career. I wish him the best. Study all you can, and if you know a buddy who is good with the Oxy-Acetylene torch, go visit him right away for some practice!
Best of Luck!

What is right for you, MIG or TIG? For certain type of work TIG is required, like welding chrome moly for some racing organizations. Intricate work, like gunsmithing is also well suited to TIG. TIG is used by many auto restorers who prefer a more precise, perfect finish that requires little to no finish work. TIG is most similar to gas welding in technique, so if you've done oxy-fuel welding, TIG should be a natural transition.
TIG stands for Tungsten Inert Gas welding. Also called GTAW (Gas Tungsten Arc Welding) and Heliarc® which was Linde's trade name for the TIG process when it was introduced many years ago. The arc is started with a tungsten electrode shielded by inert gas and filler rod is fed into the weld puddle separately. A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding.
MIG is required by law and by insurance companies in many localities for structural repair of automotive frames. MIG is also much easier to learn and faster to weld. For doing other types of welding, like sheet metal, it can be a matter of personal preference. For an auto body repair shop or a novice welder, a MIG is a good, practical all-around welder.
After welding and if application is critical , solution annealing is preferable.
