Buyer’s Guide – What To Consider?
The welding world is fascinating, just like other fields. And, if you are new, there is much more excitement level to consider buying your first 3 phase welding machine. Unfortunately, there are different welding processes suitable for each of the applications. So, understanding the overview may help you in arriving at a better decision. There is a wide assortment ranging from TIG welders, MIG welders and all the way to Stick welders offered by big players, namely Miller, Lincoln, Hobart, and ESAB among others. You may find some of the welding machines as most expensive while others are cheap. Let’s check out the ultimate buying guide for welders.
First of all, you will need to see the type of welding projects you do most of the time that requires 3 phase welding machine connection. It will determine the kind of welding machine you will require in the future. Are you welding metal sculptures? Are you restoring old muscle car in your garage? Or you need to basic repairs either on a farm or your home? Answer all these questions firstly and take your good time to identify your most time-consuming projects for which you need a welder. For instance, if you are welding exotic metals such as titanium, magnesium, it requires TIG welding process. For aluminum alloys, stainless steel or steel, all welding processes of MIG, TIG and Stick applies.
Is the welding machine easy to carry? It should be lightweight and easily transferrable from one place to another. If it’s heavy, then you will feel a bit uncomfortable to work with on operating conditions. So, portability is one of the important factors to be considered while buying a welding machine.
3. Look For Ideal Amperage
The cost of the welding machine also consists of the amount of current it can generate. Mainly, you need to consider the thickness of metals for their welding requirements. The thick metals usually require more current to be welded properly. Thus, it is mandatory to take note of the different power and amperage requirements along with the duty cycles to achieve most effective results. For best amperage go for ESAB ET 220i W1009300 Tig Stick Welder.
4. Consider Additional Costs
For operating a welding machine, you will require extra cords, equipment, and other safety material. Don’t forget to add the cost for supplies and accessories you will need to operate the welder. It can include things like a jacket, gloves, helmet, etc. along with other consumables and gas. So, if you are on a low budget, consider less expensive welder as it is further going to add the cost of accessories.
5. Refer To Its Specifications
Every welding machine comes with specific features. You need to explore them as per your requirements. It will help you further trust the machine and embrace other good features along with the welding function. The biggest factor to look is the 3 phase welding machine kw. This gives you the idea about the capacity of the welding machine. For instance, if the duty cycle of a welding machine is not accurate, it is going to damage the internal circuit and heat the machine in its overall operation.
Since the welding machines are used mostly on rough conditions like constructions sites, shipyards, junkyards etc, you want them to be highly durable. The first thing that you have to be sure of is that it should be able to take heavy impacts. Usually, the quality of the housing will tell you lot about the durability. In addition, the ergonomics and display should function well even if the unit is exposed to humidity, temperature, and dampness. If you had to ask, which is the most durable unit on our list, our answer is paste.
