Welding is a process that joins two pieces of metal by heating them together until they melt and form a joint. Welding is often used to fix things that have been broken, but it can also be used to create new pieces of metal.
Welding Basics
As mentioned, welding is a process that joins two pieces of metal by heating them together until they melt and form a joint. The weld must be strong enough to hold the pieces together, but it can also be flexible so that the joint can move and be used as a component in the finished product.
The most common type of welding is called Tig welding. Tig welding uses a special type of welder called a tig welder. Tig welders use a high-frequency current to weld metal together. This high-frequency current causes the metal to heat up quickly, which makes it easier to join the pieces together.
Welding Techniques
There are a number of different welding techniques that can be used to join two pieces of metal. The most common technique is called Brazing. Brazing uses a filler metal, such as copper, to join the two pieces of metal. The filler metal melts and forms a joint between the two pieces of metal.
Welding also can be done using a flame. Flame welding uses a flame to heat up the metal until it melts and forms a joint. This type of welding is often used to join metals that are not compatible with other types of welding.
When you use a flux core, it is very easy to make a variety of connections and has many advantages over traditional welding. In fact, the flux core process does not even require a protective gas for protecting the weld poo.
Welding with Hobart 140
The Hobart handler 140 can weld aluminum, using the correct shielding gas and wire, but it is possible that birds nest at the feed rollers, because the tube that is connected between the feed rollers and the tip of the tube is longer than the length of the feed tube. The 140 is not ready for spool guns.
It is possible for the handler 140 to work with 115 volts of common household power. Plug the thing in and weld, with the result that no additional power is required. Weld parts that are as thin as 24 gauge and as thin as 1/4 inch in one pass. Typical outputs range from 25–140 amps.
Although this hobart welder can work from any 115-volt outlet, in order to achieve maximum performance (rated thickness of the weld) you will need a dedicated 20-amp circuit.
Welding Tips
When welding, it is important to keep the following tips in mind:
– Wear safety gear, including a helmet, gloves, and a face shield.
– Make sure the metal you are welding is clean and free of dirt and other debris.
– Use a flux core wire when welding aluminum. A flux core wire contains a flux material that helps to protect the weld from corrosion.
– Keep the weld area cool by using a fan or air conditioner.
– Avoid welding in direct sunlight.
