Best quality plasma cutters
Here are several tricks on plasma cutters and how to make the best purchase choices. Welding faster may sound appealing, but aside from practice, there are few shortcuts when creating a strong weld. In fact, unless a situation calls for a fast-moving weld, there’s a good chance that slow and steady is the way to go. An online search for ways to weld faster, will yield either descriptions of the ways automated welding has increased welding speed or press releases from companies who claim their gas or electrode holds the key to improving welding speed. In other words, it can seem like spending a lot of money is the only way to weld faster. However, for those looking for some ways to save time on their welding projects, there are some ways to weld faster for certain projects. While it’s not always a good idea to find a way to weld faster, there are situations when welding faster may produce a better product or a few simple changes can speed up the time on task.
Identify the types of welding projects and materials you will weld most of the time. Are you creating metal sculptures? Do you intend to restore an old muscle car in your garage? Does the motorcycle you bought years ago require some fabrication? Maybe you need to do basic repair on farm equipment. Taking the time up front to identify the projects that will occupy the biggest percentage of your welding activity will help you determine the specific thickness of metal you will likely weld most often — and ultimately help you select the most suitable welder. Time to get a bit more specific. Let’s take a look at what welding process you can use for each metal type. Keep in mind that many of these materials are also processed using varying combinations of two or more metals to reinforce strength and functionality.
In many shops, the operator has to go to a tool room or supply area for a new contact tip, coil of wire or other welding accessory. This takes valuable time away from the welding cell and slows down overall productivity. To improve the operating efficiency and minimize wasted time, companies should stock at least a limited supply of all necessary items near the welding station – this includes shielding gas, flux and wire. Another helpful productivity enhancing tip is to switch to larger spools of wire such as from 25 lb. spools to 44 or 60 lb. spools to even larger packages of 1,000 lb. reels or 1,000 lb. drums. A simple switch like this means less changeover time, which adds up over the weeks, months and years. Shops should also be on the lookout for shielding gas waste. A simple device called a surge turbine can be placed at the end of the gun to provide a digital readout of the gas surge and flow rate. If the surge rate is high, investing in a surge guard can reduce the pressure, eliminating gas surges and waste. Leaks in the gas delivery system can also create a potential loss of money. By looking at the amount of consumables purchased each year and then examining the total gas purchased, a company can determine if there is a significant loss. Welding manufacturers and distributors should be able to provide average utilization figures so that loss can be detected. If there is a loss suspected, one of the easiest ways to check for leaks is to shut off the gas delivery system over the weekend. Check the level on Friday evening and then again on Monday morning to determine if gas was used while the system was in shut down mode. Searching for the best Welding Equipment?

Not all aluminum alloys are weldable: For example: 7075 and 2024 are not considered readily weldable using TIG welding. You can usually TIG weld them and they might be fine for a tool tote or some little art project…but don’t be fooled. You can’t depend on the welds in critical applications. Take a tree stand for instance. Lets say Joe gets a good deal on some aluminum angle iron at his friends scrap yard and he decides to make a tree stand. Joe has no way of knowing what alloy of aluminum he got from the scrap yard. He makes the tree stand, it holds together and looks just fine. The welds are real pretty…like a stack of dimes. One day he is sitting in his tree stand about 20 feet up a tree. The stress corrosion that has been happening on a microstrucutural level since he finished welding the tree stand finally comes home to roost and CRACK!!
A few TIG welders handbook: how to become a better welder and how to choose the top welding equipment. For DCEN welding on steels, 1/16″ will work in the 20 to 100 amp rage as long as you prep it right. If you are using 20 amps, you will need a needle sharp point to get good crisp arc starts. At 100 amps, you might not want quite a needle sharp point or you might be putting a smidge of tungsten in the weld. You need a blunter taper. Some charts extend the range to 150 amps for 1/16, but I think that’s way too much. Why not just swap to a 3/32 at that amperage.? 3/32″ is good from about 65 – 200 amps. And 1/8″ 2% thoriated electrodes are good in the 85 – 300 amp range. ( Drop all these numbers by about 30% for A/C) Using helium mixed with the argon will also change the recommended currents because the arc is hotter with the same amps. These recommendations are from down and dirty experience and don’t come from a chart. Most charts I have seen tell you a 1/16 tungsten is good all the way to 150 amps…Please.
Contact tips can have a significant impact on MIG welding performance since this consumable is responsible for transferring the welding current to the wire as it passes through the bore, creating the arc. The position of the contact tip within the nozzle, referred to as the contact tip recess, is just as important. The correct contact recess position can reduce excessive spatter, porosity, insufficient penetration, and burn-through or warping on thinner materials. While the ideal contact tip recess position varies according to the application, a general rule of thumb is that as the current increases, the recess should also increase.
Just about everyone who tries TIG welding feels challenged at first. This is understandable, given all the things you have to watch for and think about, while simultaneously coordinating the motion of both hands. In most cases, a foot pedal or torch-mounted amperage control will be used — for starting, modulating and stopping the flow of current. I have coached many people as they learn these skills, and I have received my share of questions over the years. Here are a few frequently asked questions — and answers — that should be helpful, particularly for beginning and intermediate welders. Source: https://www.weldingsuppliesdirect.co.uk/.
