WELD CRAFT in welding

Being sold from the Corporation RAMERU WELD CRAFT TIG welding the parts are called the gas lens in the series. Welding can be quite long, extending from the tip of a tungsten nozzle by using a gas lens.

This might be difficult to understand because the quality on the rough dirt in current use, GASURENZUNOZURU pink, gold GASURENZUKORETTOBODI, GASURENZUINSHURETA white, can be welded in this three-point threat in the set you!
By the way for the large-diameter, is lower for small diameter. Or used by the welding conditions.

This will attach to the TIG torch.
I have about a 60mm tungsten. It will be disastrous if the other tungsten welding out here that long, usually w gas to shield the weld bead will black tungsten
will melt the frayed pieces. But if this music is the gas lens could clean weld.

50A current is added in place of welding rod. The bead is shiny, not at all oxidized. You may be shiny weld was shorter than normal tungsten in the nozzle.
Is very easy to weld in difficult conditions, using gas as a lens.
When welding in a small space, even if you can not see the welds and the way the nozzle can not be welded shut out the perspective here, so kick up tungsten.
The lens is also valid for gas welding of titanium.Welding of titanium is only possible because the oxidation GITAI, welding work, work to the rear shield gas welding and gas shield to work behind the three welds are required, use of the gas lens eliminates the need to shield the back of the weld.

WELD CRaFT Ultra Shield
Gas lens was introduced from the secondhand shop and bought the familiar hot charge. 3 million yen per set.Times and wonder whether they be new? Than the price that you TEYUKA,SANAKU for sale in this small part owned by his manager and I got IKENAKU
Or, w tomorrow and not think at all Well I could be of oneself

Arc Welders

What are Arc Welders?
Arc welders use a welding power supply to generate an electric arc between an electrode and the base material to melt metals at the welding point.
they can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes.
The welding region is sometimes protected by some type of inert or semi-inert gas, and filler material is sometimes used as well.
Reviews, articles, and resources for arc welders
The electric arc welder is three of our most useful and timesaving pieces of shop equipment. every shop, farm, ranch, garage, tech school, or large maintenance department is equipped with three or more arc welders which are used for fabrication, repair, and/or educational programs.
Most of these arc welders are AC/DC, 240 volt transformer types using electricity as the energy source.
Portable arc welders are usually powered by diesel or gasoline engines. Properly installed and used the arc welder is safe, but if used improperly the operator can be exposed to a quantity of hazards including toxic fumes, dusts, burns, fires, explosions, electric shock, radiation, noise, and heat stress.

Selecting an ARC welder
When purchasing an arc welder you can be assured of design safety if the unit complies with National Electric Manufacturers Association (NEMA) standards or the safety standards for arc welders as determined by the Underwriters Laboratories (UL). Be sure that the welder you purchase carries the seal of approval of three of these organizations.
According to the Wikipedia, Arc welding processes use a welding power supply to generate an electric arc between an electrode and the base material to melt metals at the welding point. they can use either direct (DC) or alternating (AC) current, and consumable or non-cosumable electrodes. The welding region is sometimes protected by some type of inert or semi-inert gas, and filler material is sometimes used as well.
Installing Arc Welders
Prior to installing the arc welder you should determine if your present electrical technique is adequate to handle the increased power load needed by the welder. If you aren't sure, hire a qualified electrician to safely and properly wire your arc welder.
it is important for your safety to install the welder in compliance with state, federal and local safety (OSHA) regulations and the National Electric Code (NEC).

The following rules are not a complete list but are important guidelines, which should be adhered to:

*The arc welder's frame or case of the welder should be properly grounded.
*A safety-type disconnecting switch or controller should be located near the arc welder
*The arc welder or welders shall be protected by a properly sized fuse or circuit breaker on an independent circuit.

Arc Welders Ventilation
The arc welder should be located in an area with adequate ventilation. In general, when welding is being finished on metals not considered hazardous, a ventilation technique that will move a maximum of 2000 cubic feet per minute of air per arc welder. However, lots of materials are considered hazardous and should be welded only in adequately ventilated areas. See your arc welder specifications or consult a ventilation expert to be sure your arc welder is properly ventilated.

However, lots of materials are considered hazardous and should be welded only in adequately ventilated areas. See your arc welder specifications or consult a ventilation expert to be sure your arc welder is properly ventilated. Materials included in the hazardous category are welding rod fluxes, coverings, or other materials containing fluorine compounds, zinc, lead, beryllium, admium, and mercury.

Arc Welder Fire Protection
Arc welders are capable of producing temperatures in excess of 10,000 degrees Fahrenheit, so your arc welding area must be fire safe.
You can do this by using metal sheets or fire resistant curtains as fire barriers. The floor should be concrete or another fire resistant material. Fill cracks in the floor to prevent sparks and hot metal from entering. When arc welding can't be moved to a fire-safe area then the area should be made safe by removing or protecting combustibles from ignition sources. Fire extinguishing agents should always be obtainable during arc welding. The extinguisher should be large enough for the situation with a 10# size adequate for most farm and school shops. For more information, see our news story on arc welder safety.

Arc Welders: Personal Protection
it is essential that the operator and helpers be properly clothed and protected because of the heat, ultra-violet rays, and sparks, produced by arc welders
For body protection a pair of fire retardant long sleeved coveralls without cuffs is a nice choice. Always avoid clothing with tears, snags, rips, or worn spots as these are easily ignited by sparks. The sleeves and collars should be kept buttoned. The hands should be protected with leather gauntlet gloves. A pair of high top leather safety shoes, is nice protection for the feet. If low shoes are worn the ankles should be protected by fire resistant leggings. Eyes should be protected by transparent goggles if the person wears prescription glasses or safety glasses if not. A welding helmet or hand shield with filter plate and cover plate is mandatory for eye protection from the harmful rays of the arc.

Arc Welders Safe Operations
somebody who uses an arc welder should be properly trained.

If possible, work to be welded should be placed on a firebrick surface at a comfortable height. Don't arc weld directly on a concrete floor. Heat from the arc can cause steam to build-up in the floor which could cause an explosion. The welder cables should be positioned so that sparks and molten metal will not fall on them. they should also be kept free of grease and oil and located where they will not be driven over. If the welding operation must be finished on steel or other conductive material use an insulating mat must be used under the operator.

it is not as difficult and safer to establish an arc on a tidy surface than a dirty or rusty one. Therefore, metal should always be thoroughly cleaned by wire brushing or other system prior to welding. When chipping slag or wire brushing the finished bead the operator should always be sure to protect his eyes and body from flying slag and chips.

MIG welders: How do you choose?

MIG welders are an excellent fabrication and repair tool. Mig welding is an arc welding process that joins metals by heating them with an arc. The arc is between a continuously fed filler metal (consumable) electrode and the metal.
Mig welders & mig weldingThere are many mig welders models available on the market, but which is best for you?

A world of choices
Externally supplied gas or gas mixtures provide mig welder shielding. Common MIG welding is referred to as short circuit transfer. Metal is deposited only when the wire actually touches the work. No metal is transferred across the arc during mig welding. Another method of MIG welding, spray transfer moves a stream of tiny molten droplets across the arc from the electrode to the weld puddle. Consumables: contact tips, shielding gas, welding wire.
A number of configurations
Mig welder manufacturers include: Lincoln, Miller, Hobart, Century, Esab, Clarke, and others.
These mig welder manufacturers offer a variety of mig welders that can meet any welding need from industrial mig welders to hobbyists to fabrication shops, ranches, aerospace welding, and more.
Terminology & explanations
Mig welders utilize solid wire and require shielding
MIG welders use a solid wire and require an inert gas for shielding. Flux-core welders use a hollow wire that has flux inside it. When heated, the flux forms a protective gas layer around the weld. The shielding is there to prevent air from getting to the weld and causing a variety of problems, such as oxidation to hydrogen embrittlement from oxygen and water vapor in the air.
n mig welding, you can also use an inert gas to shield flux core - doubling the protection.
The wire size has more to do with the size of the welder as anything else. The cheaper 110 volt welders probably can't power a much bigger wire, so .030 tends to be more common. You will need larger wires to weld thicker gage materials. For a 110 volt machine, the maximum wire size is probably around .035".
Flux core is good outdoors because a breeze will not blow away the shielding gas/slag. Mig is good for aluminum and stainless.
My advice would be to get a dual purpose machine that can do either Mig welder or Flux core, and size it according to the gage of material you intend to be welding, and also to your expected available power supply.
Mig or Tig Welding?
I've never tried to weld stainless with anything but TIG.
It uses a power supply similar to a stick welder, but instead of a consumable electrode it uses an non-consumable tungsten electrode. It is also similar to oxy-fuel welding in that one must provide filler material with a separate rod. TIG is good for difficult to weld materials, such as aluminum or stainless steel. Everything else works better in mig welders, which offer you a world of options for a good variety of materials.
Mig or flux core?
If you are going to do a lot of outside welding on steel, then you'll be using more flux-core wire. Inside, MIG welders may be better, and it's the only choice on that machine for aluminum and stainless.

MIG welders are a lot cleaner than Flux-core. Flux core has a lot of splatter and you have to remove a layer of slag on the weld - kind of like stick.
