When working with iron, some of the iron needs to be prepared before welding. Here are some precautionary tips:
Unlike Stick and Flux-Cored electrodes, which have higher amounts of special additives, the solid MIG wire does not combat rust, dirt, oil or other contaminants very well.
Use a metal brush or grinder and clean down to bare metal before striking an arc. Make sure your work clamp connects to clean metal, too; any electrical impedance will affect wire feeding performance.
To ensure strong welds on thicker metal, bevel the joint to ensure the weld fully penetrates to the base metal. This is especially important for butt joints.

Safety Precautions Before Using MIG Equipment
Before you start manufacturing ironwork, you need to be careful with the equipment. Here are some steps you should take before you start welding:
Check your cables: Before striking an arc, check your welding equipment to make sure all of the cable connections are tight fitting and free of fraying or other damage.
Select electrode polarity: MIG welding requires DC electrode positive, or reverse polarity. The polarity connections are usually found on the inside of the machine.
Set gas flow: Turn on the shielding gas and set the flow rate to 20 to 25 cubic feet per hour. If you suspect leaks in your gas hose, apply a soapy water solution and look for bubbles. If you spot a leak, discard the hose and install a new one.
Check tension. Too much or too little tension on either the drive rolls or the wire spool hub can lead to poor wire feeding performance. Adjust according to your owner's manual.
Inspect consumables. Remove excess spatter from contact tubes, replace worn contact tips and liners and discard the wire if it appears rusty.
If you take these necessary steps, you should be able to weld safely. For more information, visit our blog page at http://upkeepingyourironwork.blogspot.com.

What Is A Sledgehammer?
A sledgehammer is a tool consisting of a large, flat head attached to a lever (or a handle). The head is typically made of metal. The sledgehammer can apply more impulse than other hammers, due to its large size. Along with the mallet, it shares the ability to distribute force over a wide area. This is contrast to other types of hammer, which concentrate force in a relatively small area.
The word sledgehammer is derived from the Anglo Saxon "Slaegan", which, in its first sense, signifies "to strike violently". The english words "slay" and "slog" are both cognate.
A sledgehammer handle can range from .5 meters (1 ft 8 inches) to a full metre (3 ft 3 inches)long, depending on the mass of the head. The head mass is usually 1 to 3 kilograms(2.2 to 6.6 pounds). Modern heavy duty sledgehammers come with 10 to 20 pounds (4.5 to 9.1 kilograms)heads. Sledgehammers usually requires two hands and a swinging motion involving the entire torso, in contrast to smaller hammers used for driving in nails. The combination of a long swinging range, and heavy head, increase the force of the resulting impact.

What Is An Anvil?
An anvil is a basic tool, a block with a hard surface on which another object is struck. The inertia of the anvil allows the energy of the striking tool to be transferred to the work piece. In most cases the anvil is used as a forging tool. Before the advent of modern welding technology, it was a primary tool of metal workers.
The great majority of modern anvils are made from steel, though other types exist.
Because anvils are very ancient tools and were at one time very commonplace, they have acquired symbolic meaning beyond their use as utilitarian objects.

What is Wrought Iron
Wrought iron is an iron alloy with a very low carbon content, in comparison to steel, and has fibrous inclusions, known as slag. This is what gives it a "grain" resembling wood, which is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile and easily welded. Historically, it was known as "commercially pure iron"; however, it no longer qualifies because current standards for commercially pure iron require a carbon content of less than 0.008 wt%. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. A modest amount of wrought iron was used as a raw material for manufacturing of steel, which was mainly to produce swords, cutlery, chisels, axes and other edge tools as well as springs and files. Demand for wrought iron reached its peak in the 1860s with the adaptation of ironclad warships and railways, but then declined as mild steel became more available.
Before they came to be made of mild steel, items produced from wrought iron included rivets, nails, wire, chains, railway couplings, water and steam pipes, nuts, bolts, horseshoes, handrails, straps for timber roof trusses, and ornamental ironwork.
Wrought iron is no longer produced on a commercial scale. Many products described as wrought iron, such as guard rails, garden furniture and gates, are made of mild steel. They retain that description because they are wrought (worked) by hand.
