High value MIG welders Ireland online and welding tricks by WeldingSuppliesDirect? How to pick a welder tips: Duty cycle: The advertised amperage of the machine offers a headline guide, but the duty cycle of the machine gives up the truth. Light industrial machine duty cycles can be as low as 20%, but more heavy duty MIG’s should range between 40-60%. If a 300amp MIG has 30% duty cycle for instance, it’s on the edge of acceptability. Duty cycle is determined by how many minutes out of 10, it can weld at 100%. Duty cycle testing: MIGS tested at 20 Degrees & 40 Degrees we consider good. (Beware any manufacturer who doesn’t quote an ambient temperature for testing) Manufacturer’s warranty: Always a great guide to quality. A three year warranty is good. Weld characteristics: Make sure the arc is smooth & suits your application. (Some machines are better suited at the low range and others at higher amperage range).
One of the “cardinal sins” that almost every shop commits is over-welding. This means that if the drawing calls for a 1/4″ fillet weld, most shops will put down a 5/16″ weld. The reasons? Either they don’t have a fillet gauge and are not exactly sure of the size of the weld they are producing or they put in some extra to “cover” themselves and make sure there is enough weld metal in place. But, over-welding leads to tremendous consumable waste. Let’s look again at our example. For a 1/4″ fillet weld, the typical operator will use .129 lbs. per foot of weld metal. The 5/16″ weld requires .201 lbs. per foot of weld metal – a 56 percent increase in weld volume compared to what is really needed. Plus, you must take into account the additional labor necessary to put down a larger weld. Not only is the company paying for extra, wasted consumable material, a weld with more weld metal is more likely to have warpage and distortion because of the added heat input. It is recommended that every operator be given a fillet gauge to accurately produce the weld specified – and nothing more. In addition, changes in wire diameter may be used to eliminate over-welding.
If you are a real handyman, you might have done some metal works, not to mention joining and installation. Yet, if you have some experience and you are ready to pick up the gauntlet of repairing metal gates or welding a pedal to a bicycle, a MIG welder is what you need! A few welding methods are known such as MMA, TIG, MIG, and MAG. We will look through MIG welders in our review. A MIG welder uses a streaming inert gas that acts as a shield and expels air contaminants from a weld zone. If no gas is used, the seam is porous and infirm. We will review household MIG welders plugged to a power outlet. Such welders can fuse stainless steel sheets and weld cracks and holes on cars, etc. We have examined 5 best MIG welders to help you buy an appropriate model for your welding needs. Also, we advise paying attention to sandblasts and that will help you get the surface prepared before welding, as well as angle grinders for cutting metalware.

The Hobart Handler 210 has the typical great quality Hobart build with durable parts that stand the test of time. The 210 is more suited to autobody repair and construction than the 190 and 140 and it welds up to 3/8 inch. It’s also a flexible unit with the capacity to weld off 115V and 230V. At under $1000 it’s lot cheaper than the Ironman 230 and is a wise choice if you’re looking for a welder that packs real power but isn’t the price of the heavy industrial welders. It you’re looking for the all round MIG package for power, versatility, quality and value for money, the Hobart 210 is our top pick. See our full review of the Hobart Handler 210 here.
A few tips on welding equipment, MIG and TIG welders, plasma cutters. TIG welding is similar to to a MIG welder as it uses an electric arc in the same was as MIG welding does but differs in a few ways. Instead of a continuous spool of consumable wire, a TIG welder uses long tungsten welding rods that are manually slowly fed into the weld puddle to join the metal. TIG welding requires gas, usually argon, to protect and cool the weld puddle from external contamination. TIG welding is more suited to welding thinner materials such as stainless steel and aluminium as you can get the power down lower to reduce the risk of blow through and can even weld two dissimilar metals. Suitable for tricky welds such as S curves but TIG welders are still capable of welding heavier materials depending on the machine. TIG welding takes more practice that MIG welding as the process is much more manual with controlling the torch, welding rod and gas by hand (and foot for the gas) but once mastered will produce the highest quality welds making it the better choice where perfect, precise welds are required but due to the manual process is the least productive.
USA market pick: Like LOTOS Technology and LONGEVITY Inc, Everlast has a little over a decade in experience. It is a California company which was founded in 2004. The light and efficient Everlast welder has one of the best duty cycles on our list. With the most basic of designs, this Everlast power-mig welder is perfect for novices. Along with other welders with 4, 7, or 10 voltage settings, the Everlast has infinite settings for voltage and also wire speed, making it a customizable experience. The Everlast 140amp MIG welder can cut mild steel, stainless steel, as well as chrome-oly at a thickness of 3/16 inches. It can be used with both four-inch and eight-inch wire spools. It’s incredibly lightweight for the power it gives out. Discover more info at https://www.weldingsuppliesdirect.ie/.
