Oxford Mig welders best prices: Identify the types of welding projects and materials you will weld most of the time. Are you creating metal sculptures? Do you intend to restore an old muscle car in your garage? Does the motorcycle you bought years ago require some fabrication? Maybe you need to do basic repair on farm equipment. Taking the time up front to identify the projects that will occupy the biggest percentage of your welding activity will help you determine the specific thickness of metal you will likely weld most often — and ultimately help you select the most suitable welder. Time to get a bit more specific. Let’s take a look at what welding process you can use for each metal type. Keep in mind that many of these materials are also processed using varying combinations of two or more metals to reinforce strength and functionality.
To us solid build & rugged reliability & long lifespan is just as important as welding performance! By designing our machines to be very electrically efficient we achieve performance levels much higher than other machines on the market, for example 400A + MIG welding on 230V single phase, Plasma cutting up to 36mm steel on 230V single phase, etc. Our OXFORD range now extends to around 50 different models & includes MIG, TIG, PLASMA, PULSE MIG & multi-process machines with ARC (MMA) MIG & TIG functions. Despite the ever increasing amount of low cost cheap imports available, our sales continue to grow year on year & we now have a good share of the UK market with additional export business.

Before you get started, conduct online research to see what the best practices are for the specific wire you have or contact a trusted filler metal manufacturer. Doing so not only tells you what the manufacturer’s recommended parameters are for your diameter wire, but also what the proper wire feed speed, amperage and voltage is, along with the most compatible shielding gas. The manufacturer will even tell you what electrode extension or contact-to-work distance (CTWD) is best suited for the particular wire. Keep in mind that if you get too long of a stickout, your weld will be cold, which will drop your amperage and with it the joint penetration. As a general rule of thumb, since less wire stickout typically results in a more stable arc and better low-voltage penetration, the best wire stickout length is generally the shortest one allowable for the application.
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.
