Several MIG welders advices

A few advices about welding equipment, MIG and TIG welders, plasma cutters. A welder is a long term investment where many find that they get what they pay for. While it is sometimes advisable to test the waters with a used model, picking the right machine the first time around can save a lot of headaches and cash in the long term. No one wants a used welder to fail in the middle of a big job or to discover that a used welder’s price can help make ends meet but the welder itself can’t make two pieces of metal meet. The best welder will complete every project that comes down the pike and minimizes limitations. This means that the most expensive welder is not always the best for each situation. However, the cheapest welding machine that can’t handle every job a welder hopes to accomplish fails to pay for itself in ways that make it worthwhile to review the possible options before investing in a welder.

Several welding equipment tricks: how to become a more skilled welder and how to choose the best 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.

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. Looking for the best Welding Fume Extraction?

Argon is not the only shielding gas used for TIG welding: Shielding gasses for TIG welding Argon is not the only shielding gas used for TIG welding…just the most common and versatile. Argon will usually get the job done. But there are times when some helium mixed with argon makes a world of difference. Especially if you are using a small inverter TIG welder that is limited to around 200 amps. 100% Argon – is the most often used and coolest gas ..the best all around gas. 75% Argon/25% Helium – even 25% helium will make a big difference when welding aluminum that is thicker than .063″. Anything under .063″ thick and helium is unnecessary. 50/50 argon/helium—awesome for thick aluminum and magnesium 75% Helium/25% Argon – Awesome for thick aluminum castings… puddles really quick and welds cleaner than 100% argon. Also good for welding bronze and pure copper on DCEN.

MIG Welding Increases Welding Speed: In addition to welding aluminum and other softer metals, MIG-welding works faster, provides cleaner welds, and handles many different types of metals. The downside is its complexity. MIG Welders need direct currents, a steady stream of inert gas, and precise control of their torches. The amount of heat generated from MIG welding provides the deep penetration required for a strong weld, while also melting the feed wire rapidly enough to maintain a higher welding speed than other techniques. Given the inert gas required for MIG welding, keep in mind that this technique cannot be conducted in windy areas. The Right Stick Electrode Increases Welding Speed: There are three kinds of electrodes used for stick welding: fast-fill, fill-freeze, and fast-follow. While each electrode has its advantages, the fast-fill electrodes melt quickly and allow welders to work faster.

Before you start welding, make sure all of your connections are tight — from the front of the MIG gun to the power pin attaching it to the power source. Also be certain there is no spatter buildup on your consumables and that you have a ground cable as close to the workspace as possible. Whenever possible, hook the ground cable on the weldment. If that is not possible, hook it to a bench. But remember: The closer it is to the arc, the better. If you have a questionable ground, it can cause the gun to overheat, impacting contact tip life and weld quality. In addition, regularly clean any shavings from the welding wire or debris that collects on your consumable parts and in your liner using clean compressed air.

All welding requires the application of heat, which melts the metal being welded. With the TIG process, the heat comes from an electric arc that streams between the electrode in a hand-held torch and the metal being welded. The arc and molten metal are shielded by an inert gas, which protects the electrode and base metal from oxidizing. Filler rod is usually added to the puddle of molten metal as the weld progresses. The essence of making a good weld is heat control, which is governed by how you modulate the arc as it streams from the torch. Let’s look at this in detail.

Best nespresso machines

I will review some of the best latte machines. Another De’Longhi creation is the 15 Bar Pump Espresso and Cappuccino Maker. It is a bestseller in the field of semi-automatic espresso machines. What sets De’Longhi’s model EC155 apart is its 15 bar pressure pump. This means optimal brewing pressure is used to make your espresso. It comes with a small built-in tamper and a frothing wand. This model is suitable for those who want to experiment on getting an espresso machine, but are not serious or knowledgeable enough to get a more expensive automatic machine.

DeLonghi ESAM3300 Magnifica Super-Automatic Espresso/Coffee Machine : Even though one user admits, “This is by far the most expensive coffee/espresso/cappuccino machine I have bought,” they “don’t regret it for a single moment.” Like many, this person believes the ease of this machine makes it worth the price. “The machine is super-easy to operate — no grinding, filling espresso cup or filter, operating messy frothing nozzles, etc. All I need to do is pouring coffee beans, selecting flavors/strengths, filling water tank, and pushing the desired buttons.” The built-in grinder is mentioned in dozens of reviews as a standout. “I worked in so many coffee shops over the years and always wanted a nice machine at home,” one reviewer writes. “The problem was I didn’t want to spend $400 on a good burr grinder. This amazing machine comes with one inside the machine!” Another says the “best part is it’s super-customizable, and all you have to do is drop fresh beans in and it does the rest.” Another happy user appreciates having “no problem grinding any type of bean”: “We use very oily, dark-roast beans which often cause problems with grinders, but with the Magnifica it’s been a minor issue.”

Best Large Capacity: Capresso Perk 12-Cup Percolator: This 12-cup coffee maker is great for families who want more than just a cup or two of coffee, or for serving a cup after a dinner party, but it can also brew as little as 4 cups when you don’t need a full pot. It’s made from stainless steel and has an automatic keep-warm function, so you can get the pot set up before dinner and it will wait until guests are ready for their after-dinner brew. If you need a second round of coffee, this brews a pot in less than a minute. This makes it easy to set up, since there are markings inside for coffee and water amounts, so you don’t need to measure. When it’s time to serve, the cord is detachable, so it won’t get in the way, and the spout is designed to be drip free. This should be hand washed.

The Essenza Mini is small and mighty, capable of making the same ristrettos, espressos, and lungos as any other Nespresso machine in its line. Its slim, attractive frame can fit in even the smallest kitchen, and its simplicity makes it the easiest Nespresso machine to use and clean. Don’t be bamboozled by the wide array of machines that make you pay hundreds of dollars more for features that won’t make your coffee taste any better, such as Bluetooth technology or a latte art wand. The Essenza Mini offers the most bang for a still-sizable buck. Interested to buy affordable espresso machines? See more details on percolator coffee maker.

Nespresso D121-US4-BK-NE1 Espresso Maker with Aeroccino Milk Frother: This user-friendly Nespresso machine makes brewing a cup of espresso or other milk-based coffees convenient and easy.

Tungsten size should be selected mainly according to amperage AND polarity: Tungsten size should be selected mainly according to amperage AND polarity and not always dependent upon metal thickness. When TIG welding aluminum, If your tungsten begins to ball up and quiver, this means your tungsten is getting near its capacity. This can be minimized by using the A/C balance dial and setting it for more penetration and less cleaning…or if you are using a TIG inverter like a miller dynasty, the a/c balance should probably be set to 65-70% EN. For transformer machines like the syncrowave, The a/c balance set to the cleaning side means more of the dcep side of the a/c wave which means more heat is on the tungsten tip = more wiggling. The more to the penetration side, the more the arc is on the negative side and the Less heat on tungsten tip and less cleaning action but the square wave usually provides enough cleaning anyway even in max penetration mode.

Look for ways to support your hands. Having good support for your hands or arms is crucial for moving the torch with precise control. I do my best welding when the base of my hands or my wrists is supported in some way. Often you can rest your wrists on the part being welded. I keep an assortment of wood and metal blocks near my welding bench, and I often can get better support by positioning a block to rest my torch hand on. There are occasions where I rest my forearms, or even my elbows, on something for support. Many welders set up special support bars, positioned parallel to the joint being welded, and they slide their torch hand along the bar to help follow the joint with fine control. For some out-of-position work, I’ve had to rely on resting only my shoulder on something, and while not ideal, it’s better than having no support at all. Even placing my hip against something stationary can offer a bit of support, but I can’t weld very well when standing ‘free,’ with no support at all.

For the best control of your weld bead, keep the wire directed at the leading edge of the weld pool. When welding out of position (vertical, horizontal or overhead welding), keep the weld pool small for best weld bead control, and use the smallest wire diameter size you can. A bead that is too tall and skinny indicates a lack of heat into the weld joint or too fast of travel speed. Conversely, if the bead is flat and wide, the weld parameters are too hot or you are welding too slowly. Ideally, the weld should have a slight crown that just touches the metal around it. Keep in mind that a push technique preheats the metal, which means this is best used with thinner metals like aluminum. On the other hand, if you pull solid wire, it flattens the weld out and puts a lot of heat into the metal. Finally, always store and handle your filler metals properly. Keep product in a dry, clean place — moisture can damage wire and lead to costly weld defects, such as hydrogen-induced cracking. Also, always use gloves when handling wires to prevent moisture or dirt from your hands settling on the surface. When not in use, protect spools of wire by covering them on the wire feeder, or better yet, remove the spool and place it in a clean plastic bag, closing it securely.
