Engweld and welding machines online shopping? The MIG welder performance depends on several parameters. The duty cycle is among them. It means the percentage of a 10-minute period the welder can work until it gets overheated. For example, “90A / 20%” means that a welder can work for 2 minutes at 90A before an 8-minute cooldown, i.e. 20% of 10 minutes. Now, about the material. We should note that the maximum thickness of a material a welder can handle depends on its amperage and welding wire thickness. Lastly, consider the thickness of the joint a welder can make in a single run. Household models can weld metal sheets from 18-gauge to 1/4” thick at the output of 70A – 180A, respectively.
How to pick a welder tips: Fan on demand: Lowers running costs and reduces contamination to internal components. The fan kicks in when it’s needed, rather than running all day. Printed Circuit board protection: If the machine’s PCB’s are protected from dust & kept away from the fan, reliability will increase. Some manufacturers’ have the parts that need cooling in a duct type housing & the PCB isolated separately. Step voltage settings: If you’re looking at step voltage conventional MIG with multiple power settings – “the more the better!”
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’re a beginner welder but don’t mind splashing the cash for a top of the range welder, then try the Millermatic 141. Miller have really pushed the boundaries of usability with this welder and it features an auto-set feature for an easy set up, and infinite voltage and wire speed control. All you have to do is select the thickness of the metal you’re welding and you’re ready to start welding straight away. If you open up the machine you can tell that all the parts are great quality and really durable as well. There are more powerful welders on the market for the price, but there’s nothing better for welding up to 3/16 inch steel. See the full review here.
Several tips about welding equipment, MIG and TIG welders, plasma cutters. A MIG welder uses a continually feeding spool of thin filler wire as an electrode fed by a wire feed gun to form an electric arc between a wire and the work-piece metal. This heats the work-piece metal and the electrode, causing them to melt and join together to create the weld. Mig welding can be either Gas or Gasless and each have benefits. Gasless welding is far more portable as there’s no gas bottle to carry around, saves cost on having to buy gas bottles and regulators, is easier on positional welds and can penetrate deeper than Gas MIG although the welding wire for a gasless MIG is more expensive than a gasless MIG. Gas MIG welding produces much cleaner welds with no slag or spatter, is slightly better on thinner metals and the welding wire is cheaper than gasless MIG wire.
USA market look: Hobart is an American welding company that has produced quality machines since its inception in 1917. Often toted as the best MIG welder for beginners, the Handler 140 is an affordable and easy to use machine right off the bat. Though its duty cycle is on the low end when compared to the other welders on this list, the Handler is a crowd favorite. It is also fairly easy to carry. Welders will love the portability and ease of use. A home hobbyist will get years of use and enjoyment from this powerful machine. All in all, it’s a very sturdy machine and is manufactured in the USA. Find more details at https://www.weldingsuppliesdirect.co.uk/.
