Sealey is one of the biggest manufacturers of tools and accessories in the UK, offering approximately 8000 items including tools for home, repair shops, agricultural facilities, as well as cleaning. In this variety, we found a gasless MIG welder MIGHTYMIG 100. The machine is able to weld metal sheets of a different thickness thanks to a toggle that allows setting the amperage to the minimum and maximum. The output range will be 55? and 100?, respectively. We should say that the welding time at the minimum power won’t be over 6 minutes. Yet, this welder will run for about 2 minutes at 90? and that’s great considering its moderate price. In addition, you’ll be able to manage the joint by varying the speed of the wire feed, just turn the relevant control knob to the desired setting. By the way, the welder is compatible with a flux-cored wire up to 0.9 mm, and the weight of the spool should be 0.9 kg. Like most welding tools, it features an overheating protection, and the orange light will notify you when the welder gets overheated after a long use. Apart from that, the forced air cooling system will chill the welder’s internal parts. The welder has a non-live torch for your convenience that will increase the accuracy of welding and provide safety.

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).

Look for ways to create more efficiencies in the welding process. This includes examining such things as wire diameter, wire feed speed, voltage, travel speed, gas type, transfer mode, etc. For instance, if the shop is currently welding with a short arc process and a 75/25 blend of shielding gas, it may be more effective to switch to a different gas and a spray mode of transfer. Or, a change in process may be warranted based on the condition of the part. If there is oxide on the part, it may be easier to change to a process that will overcome contamination problems rather than try to clean each part before welding. Your welding supplier should be up to date on the latest technology and be able to advise you on new processes, machinery and consumables that can optimize welding at the shop. In some cases, it may be better to double bevel a joint to prepare it for welding rather than single bevel it. It is recommended to double bevel any material that is more than 3/4″ in thickness. Just this simple change in procedure can save quite a bit in weld metal. On a 3/4″ thick piece, a double bevel will use 1.45 lbs. per foot of weld metal while a single bevel will use 1.95 lbs. per foot.

Several tips about welding equipment, MIG and TIG welders, plasma cutters. Stick Welding — If you learned to weld years ago, you likely learned using an arc welder. Stick welding for many years has been the most popular method for most home-shop welding needs. This process uses an electric current flowing from a gap between the metal and the welding stick, also known as an arc-welding electrode. Stick welding is an effective method for welding most alloys or joints and can be used indoors and outdoors or in drafty areas. It’s also the most economical welding method and provides the ability to create an effective bond on rusty or dirty metals. However, this method is limited to metals no thinner than 18-gauge, requires frequent rod changing, emits significant spatter and requires that welds be cleaned upon completion. Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It’s used for welding thicker metals of 1/16 inch or greater. These machines are a good choice for farmers, hobbyists and home maintenance chores. Discover more info at MIG Welders Online Store.

USA market dive: LONGEVITY Inc is a company that has been around since only 2001. Like LOTOS Technology, it still produces a fine enough quality welder that it has earned its spot on this list. Besides the gas cylinder, this welder comes with everything you need to get started and is simple to set up. With all this, along with its solid performance, this machine is marked at a fair price of under $400. Though it is manufactured in China, the LONGEVITY Migweld is still a quality welder. It is most well-adapted to light use. Compared to Miller and Hobart’s machines, the price is somewhat better without sacrificing much quality. It welds from 24 gauge to ¼ inches of steel. Flux core is available for this welder. The LONGEVITY can run at ten different voltage settings. As an added bonus, it has thermal overload protection like the LOTOS welder.

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.
