Hobart Handler 210 vs Millermatic   by Easy Metal Works

The Hobart Handler 210 is the portable (weighing only 76.5 lb or 34.8 kg, so you can take it easily from jobsite to jobsite) MIG welder that has maximum of 210 amps of welding power for handling 3/8 inch thick mild steel and enough control for 24 Gauge material. It is designed to handle a variety of materials including mild steel, stainless steel, and aluminum. The ease of connecting an optional direct plug-in spool gun expands the capability of the Handler 210 for aluminum welding.

It has enhanced magnetics and infinite wire feed speed control offers easier fine control of the output parameters for improved arc performance with less spatter, resulting in a better bead appearance and less cleanup.

If you have to do aluminum works, you have probably heard that TIG is the right choice for that. Not this time – Handler 210 welds aluminum as well as steel. You do get a bit of black but that easily wipes off as the magnesium in the aluminum oxidizes.

Ergonomics & Safety. Built-in contactor for easy use is also an excellent safety feature which makes wire electrically “cold” when not welding. You will have easy access to polarity changeover includes storage holes for spare tips. Dual groove drive rolls make it easy to switch between .023/.025-Inch (0.6 mm) and .030 to .035-Inch (0.8 – 0.9 mm) wire. And self-resetting thermal overload and motor protection prevents overheating.

Comparison. The Hobart 210 and similar Millermatic equivalents (Millermatic 180, 210, 211) have pretty much the same output, duty cycle and they use the same drive mechanisms. The feel and weld quality should be virtually identical. So what are the differences?

The Millermatic is a dual voltage machine that can operate on 230 or 115 volts. That means it would be easy to take it to a buddy’s house and weld lighter materials by plugging into a standard 115 volt circuit (20 amp service). However in order to take it with you, it should to be light. Millermatic does not fall into that category and also costs up to two times as much.

Millermatic offers adjustable voltage up to 7 positions, which might seem as a big plus, however experts sometimes consider infinitely adjustable voltage control not to be an advantage over the tapped voltage units. Tapped voltage units are easier to setup and get the arc dialed in.

The Millermatic will be of a slightly better build quality since Miller now owns Hobart and sells the Hobart as a lower cost alternative to the Millermatic line. They don’t usually skimp where it really counts though. Things like the drive mechanism will most likely be identical.

Hobart also offers more current for welding aluminum, so if you are uncertain so far but are planning to work mostly with aluminum go for Hobart. Spool gun coming with Hobart is the Miller Spoolmate 3035 equivalent.

Tig Welder Salary

Underwater welding and its risks   by Oleg Gladshteyn

Welding is a riskier job, in spite of being qualified; there are several welders who are prone to injury often. The most risky part is underwater welding. Welding needs are in tons and it requires a great effort to become a welder-diver. Apart from knowing the technical aspects concerned to welding, he or she should be a person who is proficient in diving because without that it is difficult to become a welder-diver. However the salary they earn is covered in a wide range. And this article is all about the basics of underwater welding and the risks involved in it.

Underwater welding is basically performed on steel and it is a definite need that the person who performs underwater welding should be thousand times superior to the commercial divers. The task includes repairing pipelines, offshore oil platforms and ships.

Also there are different types of welding which could be performed underwater but then the most commonly done welding technique is the arc welding. There are several applications concerned to the underwater skills which also include darning ships, working on oil platforms and sustaining underwater pipelines. People with skill and practice in this field can find employment all over the world. The possibility of electric shock is very high as the person should do the welding process by staying inside the water.

The task is carried out by specialized welders and they are specially trained to work under water. This is very helpful for several companies because lifting the structure away from the water is difficult though it is possible it costs a huge sum of money also waste of time. Thereby to overcome this disadvantage underwater welding has headed out. This underwater welding can be classified into two types namely dry welding and wet welding.

Mig welding and tig welding process can also be done under water. But then the exact details relating to the water pressure levels should be identified. Portable welding machines are of great use and portable welders can also follow the proper set of guidelines to follow under the water to have a safe welding. Since underwater welding is performed on steel very rarely you get to into the process of welding aluminum.

The necessary equipment like welding guns and metal cutters should be carried. He or she wears a dive suit, and utilizes welding tools that are tailored for wet environments. And this customized equipment will help the person to safeguard from electric shocks. On the whole, someone who undertakes underwater welding as their profession should be a good welder as well as a good diver.

Controlled power supply can avoid electric shocks under the water. The major risk associated with the underwater welding is an explosion. Hydrogen and oxygen are great explosives and when ignited it can lead to an underwater explosion.

To sum up it is one of the riskier tasks in a welder’s life so before performing the task it is necessary to follow the exact guidelines to avoid injuries.

Understanding what TIG Welders can actually do   by mspaul

TIG welding called tungsten inert gas, also known as Gas tungsten arc welding (GTAW), is considered as an arc welding process that makes use of a non consumable tungsten electrode in order to produce the strong weld. The new procedure based on GTAW was first introduced in 1953, called plasma arc welding. GTAW is the most commonly used process that is used to weld thin sections of stainless steel and light metals including aluminum, magnesium, and copper alloys and also some other metals except for lead and zinc.

The method allows welding operator a greater control over the weld than other competing procedures like as in shielded metal arc welding and gas metal arc welding, providing stronger and higher quality welds. One of the biggest advantages of the TIG welders is that it heats and joins two or more metal pieces together without making use of any filler materials. Unlike other types of welders, TIG machines require more skills and practice in order to be used properly. And, through this way the possibility of preventing cracked seals or damaging the weld are also decreased.

As a fact, this kind of automotive service equipment melts and combines the two or more metal pieces together rather than making use of melted metals in order to join them together. Also, you will simply find that this method has a high level of precision and accuracy. Listed here are certain advantages as well as disadvantages of TIG welders.

Advantages:

1. Best welding system to weld thin materials
2. Concentrated arc
3. No kind of slag
4. Can easily weld more than two metals and metal alloys than any other process
5. No sparks and spatter

Disadvantages:

1. Little slower speeds than other processes.
2. Requires careful coordination of hands and eyes.
3. Contain brighter UV rays than what other processes involved.
4. Have lower filler metal deposition rates.
5. Higher equipment costs than other welding procedures.
6. Also, the process needs to have concentrations of shielding gas that might build up and can even displace oxygen while welding is done in confined areas.

Welding is important in manufacturing industry   by John Peter

Welding is a word that gives sound like two different expressions such as well+ ding, so with the sound you can just assume it as a method that is well matched for manufacturing industries. The word “ding” is actually a Chinese container that has 3 legs for its support, likewise welding is a method that requires support from welders, accessories and supplies. As a chair can’t stand properly without legs in the same way welding also stop working if there is no appropriate equipments.

Usually manufacturing is a method that utilizes machines, tools to make goods and manufacturing industries is the one where the raw materials are being changed into finished goods or products. Without connecting two or more metals and any other items products can’t be produced, hence welding is very valuable in these types of industries. Most of the manufacturing industries are using this process and some of the major users that utilize the application of welding equipment are automobile, electronics, metal casting, aerospace and many more.

There are a number of processes in automobile industry such as traceability and part tracking and these developments entail to use the application of welding equipments. Some sectors are there that make the metals and apparatus for the people and it’s not possible to weld a metal without getting help of welding process or tool. Welders are extremely helpful without them process can’t be completed. They are called the backbone for manufacturing industry because these are the machines that applied to fuse the metals.

Metal is the major concern in industrialized business and the unprocessed metals are not valuable if they are not shapes and fused properly. Therefore in the view of fact, welders and equipment play a very important role in mechanized business. One has to remember that without the help of particular welding supply it is not probable to fuse all kinds of metals. For each and every metal you need different equipments and professionals such as, if you fuse steel or any other non-ferrous metals then TIG are useful. On the other hand, for other categories of metals different machines are used.

Based on the different- different functions, there are various types of welding accessories are being used in industries. As the technology is developing drastically, different types of machines have introduced in market and each one has their own qualities. In the process of TIG, particularly aluminum, steel, copper and magnesium are being fused. Whereas MIG specially is utilized for aluminum and steel and it takes lower fusing time than to other processes. Iron, copper, steel, aluminum and nickel are usually fused by Stick Welding. Multiprocessing units are very helpful for all kinds of spot repairs in industries. Once upon a time no one was familiar with the fusing process, however in the present day everyone came to know it got spread widely and reached in peak now.
