Oxford welders top offers: What factors should you consider when determining a budget? You may already have an estimated budget in mind. The type of welder you purchase should be suited for the specific functions you require as well as the projects you will work on the most. Think about your end goal and consider opportunities to expand the usefulness of your welder. Will you want more power or amperage in the future? It is important to take note of the varying amperage and power requirements as well as the duty cycle necessary to achieve the most effective and economical operational results for the projects you’re looking to complete. In addition to the cost of the welder itself, don’t forget to include costs for the accessories and supplies you’ll need to operate your new welder. This includes welding protection (helmet, gloves, jacket, etc.) as well as gas and consumables.
The power electronics have to work at the mains input voltage which is in excess of 630V on a three phase machine & in excess of 340V for single phase with peak voltages often in excess of 800V. This is not an easy task for any electronic mosfet or IGBT & in most machines there are multiple IGBT’s or mosfets all working together. Then when you add real welding conditions such as damp & dust, voltage fluctuations & spikes it just becomes a matter of time before a failure occurs. Some of the quality US & EU manufacturers have tried to address this by designing machines with separate compartments or wind tunnels to keep critical componants away from dust & damp etc. This has improved reliability in some cases, however by nature all inverter based machines are fairly fragile. Furthermore inverters are increasingly using complex microprocessors, computers are fine on a desk but in a dirty welding machine? More problems! However inverters do you have a place, if you need a machine where portability is the number one priority then consider a quality EU or US made inverter but keep it simple, more complex functions often means more to go wrong!

Never forget that welding, when done improperly, can be hazardous. Electric shock, fumes and gases, arc rays, hot parts, noise and a host of other possible hazards come along with the territory. The ultraviolet and infrared light rays can also burn your skin – similar to a sunburn but without the subsequent tan – and your eyes. This is why the best MIG welding operator knows how to stay safe. Following some simple tips can help you take your MIG welding operation to the next level and ensure you are as safe, efficient and professional as any other shop. Welding helmets, gloves, close-toed shoes and clothes that fully cover exposed skin are essential. Make sure you wear flame-resistant natural fibers such as denim and leather, and avoid synthetic materials that will melt when struck by spatter, potentially causing burns. Also, avoid wearing pants with cuffs or shirts with pockets, as these can catch sparks and lead to injuries.
Eliminate Any Extra Welds from the Design: Look for ways to modify product designs to eliminate unnecessary welds. For example, one company that manufactured boxes originally had a design that called for welded lift handles on each side of the box. By simply changing the design of the box to cut out lifting slots, it eliminated the need for welding the handles – saving time and money. In another instance, rather than making a part with an open corner, the design was changed to accommodate a closed corner, which meant 1/3 less metal required to fill the corner. Look for Items That Can Be Welded Rather Than Cast: We’ve already discussed ways to eliminate welds to create efficiencies, but what about adding welds? In some cases, it may be more cost effective to weld metal pieces to a part rather than cast the entire component in a costly alloy or exotic metal. For example, a company that originally used a part cast in a high-nickel alloy found that 50 percent of the part could be composed of standard, structural steel which allowed a savings in material and thus a savings in total cost. Also, the company was further able to redesign the part so that it was more efficient. Explore a few extra info at https://www.weldingsuppliesdirect.co.uk/.
