MIG welders are divided into transformer and inverter models. Briefly, transformer machines feature only mechanical parts that can adjust the output voltage “sequentially” while the unit is off. The output voltage is not stabilised and may decrease under load. Still, a simple design is the main benefit of transformer welders that facilitate their maintenance. Also, they are often cheaper. Inverter MIG welders are fitted with electronics that allow a smooth voltage adjustment, so it isn’t susceptible to drops and does not fall under load. Of course, power is the main feature of any electric tool. As for MIG welders, their power depends on the maximum amperage, more usually, the output range. This range determines the unit’s field of application. Powerful models can be used on small construction sites or in repair shops, while less powerful models are usually used for private needs. For example, the welders of up to 200A are great for home use; the 300A models are suitable for small repair shops, and if you need a high output and continuous work, consider welders over 300A.
How to pick a welder tips: Stepped voltage or synergic: Synergic MIG’s have the edge when you’re welding stainless & aluminium as they are pre-programmed, easy to set up & portable. They also provide a better weld characteristic and so give cleaner weld bead with less/no spatter. Inverters: Considerably smaller and lighter and so ideal for site work. All inverters are stepless and so have infinite control. Also cheaper to run power wise. Budget: How much welding are you going to undertake? Gear your purchasing decision around the jobs you will be working on the most. Polarity changeover; A lot of welders at the light industrial end will to be able weld with gasless flux cored MIG wire. Is the switchover easy on the machine you’re considering. Availability of spares & after sales service: Ask where the machine is actually made. Even the more recognised brands largely outsource their production, which can lead to quality and after sales issues with lack of continuity of supply for spares.
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.
Some advices on welding equipment, MIG and TIG welders, plasma cutters. ARC Welding : ARC welding is one of the oldest welding processes around. It uses either an AC or DC power supply to create an electric arc between the welding rod and the workpiece metal to melt the metals and join them together. This style of welding is relatively inexpensive and very portable but it does require some practice to get good consistent welds and the welds will probably require some arc weldercleaning up afterwards. ARC welding is less suited to welding thinner materials but there is a large range of specialist electrodes (welding rods) available for ARC welders depending on what materials you are welding. ARC welding is versatile but more suited to heavier applications. Read additional info at https://www.migwelders.ie/.
USA market pick: At just $99, the Goplus is a fantastic value considering what it is equipped to do. In fact, it is the most affordable welder on our list, beating out its competitors by hundreds or even thousands of dollars and putting it in a class of its own. For a budding hobbyist not yet sure if welding is for them, you can’t go wrong with the Goplus. After all, for $99 its welding thickness and the duty cycle is about what one would expect (don’t look to buy this welder if you want it for heavy duty use). The Goplus is light and compact when compared to most other welders. Flux core wire is included. It has four levels of easily adjustable current flow and ten levels of wire speed. The Goplus is able to weld steel and iron at below ¼ inches thickness.
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.
