ZThe following factors should be revised just before making a purchase of a plasma cutting machine.
Establish the thickness
This is a vital factor. Plasma cutters are valued according to their amperage and cutting ability. To cut thick materials go in for a cutter that has lover amperage.
Decide on Cutting Speed
If the purchase is for commercial usage then go in for a cutter that provides higher amperage. Although this does not matter much, it is always best to buy the one is specially made for the purpose. If the plasma cutter is bought for rare usage and need not essentially be fast at its work then go in for the ones that offer lower amperage.
Alternative to High Frequency Starting
Many cutters contain a pilot arc. The high frequency that it utilizes may affect office equipments and computers.
Consumable Cost vs. Consumable Life
Torches in cutters are available in a wide variety. Check for a manufacturer who provides with the fewest number. This will result in cost effectiveness. Also check out the length of life of the consumables.
Scrutinize the Quality
Make examination cuts on a number of equipments, moving at the equal rate of pace on the similar depth of substance to observe which equipment offers the most excellent value. As you contrast cuts, inspect the shield for dross on the base and notice if the kerf angle is at right angles or angular. Look for a plasma cutter that offers a tense, alert arc. An additional check to execute is to elevate the plasma torch up from the plate while cutting. Observe how far you can progress the torch away from the work section and still uphold an arc. A longer arc results more volts and the capability to cut all the way through thicker plate.
Pilot to Cut and vice versa
Look for an instrument that offers a rapid, optimistic shift from pilot to cutting at a huge shift height. These equipments will be more tolerant to the machinist and will in good health sustain gouging. In these instances, the apparatus will be obligatory to swiftly shift from pilot to cut and back to pilot extremely fast. To acquire something like this, they may advocate you cut stretched out metal using only the pilot current.
Working Visibility
As you are operating on an appliance, you would like to observe what you are cutting, more than ever when tracing a prototype. So make sure that this is not hampered with by your plasma cutter.
Portability
A lot of regulars use their plasma cutter for an assortment of applications and call for to shift the machine in the region of a plant, job location or even from location to location. A portable cutter is the most need at these times.
Austerity
Go in for a piece of equipment that is durable and has confined controls.
Comfort ability and ease
Go in for a cutter that has easy-to-read control panel

Help answer the question about welding tig
Why is TIG welding superior to MIG when welding 4130 chromoly for aircraft construction?MIG is so much easier and produces a clean weld for flat stock. Why not use it for fuselage construction also?

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 for the reply! – funny your comment was removed – author, you should allow the sharing of knowledge..very sad.
walking the cup
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.
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
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,
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!
You will weld in accordance to the weld procedures that will be given to you for the specific materials mentioned.
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
Welds are probably huge by the way he’s slinging the tungsten around.

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.
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 !
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.
Thanks bozzza – cheers to all those who share their experience and help others
Please read:
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.
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!
