High quality Welding curtains shopping United Kingdom right now with WeldingSuppliesDirect: Resistance or pressure welding uses the application of pressure and current between two metal surfaces to create fusion. Workpieces are placed in contact together at high pressure with a current passing through the contact point. The resistance in the metals generates heat which fuses together the metal surfaces of the workpiece. Resistance spot welding (RSW) uses two electrodes to press together overlapping metals while a welding current is applied through the resistive metals. Heat is generated and the metal surfaces fuse together to create a weld joint in the shape of a button or nugget. Metals are fused using large amounts of energy in a short time span (approx. 10-100 milliseconds) joining the workpieces almost instantaneously. The area around the weld nugget stays unharmed by the excessive heat, thus the heat-affected zone is minimal with spot welding.
The following tips may help: Use the right type of regulator for the gas cylinder. Take care to inspect the regulator before attaching to the cylinder. If the connections aren’t properly made, perhaps you might be using the wrong device. Thus, it is wise to replace it with the right one. Close the valve of the cylinder, as well as release the pressure from the regulator, before removing it from a cylinder. Remove the regulator from the cylinder while transporting it to another location.

Metal Inert Gas (MIG) and flux core wire-feed welders have completely revolutionized small-scale welding over the last couple of decades. Whether it’s hobbyists needing welders for DIY projects or professionals that deal with sheet metal on a daily basis, the modern MIG delivers an amazing impact on productivity. With the huge influx of Chinese and other foreign-built products on the market, prices are hovering at all-time lows. The biggest problem might actually be narrowing the huge selection down to the right machine at the right price. A professional welder needs quality and reliability above all else, while a DIY guy at home might be most concerned over the actual price of putting a MIG in the garage. We’ve put together a list of what we think are some of the best MIG welders available today along with reviews to help you choose.
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.
How to pick a welder tips: Digital meters factory fitted: Great to have when you purchase and may be required for calibration requirements. To fit them down the line could be expensive. Drive rollers: Metal rollers are the best. Nylon & plastic ones will always wear away quicker. Drive block system: Four roll would always be first choice, but some of the lower amperage machines won’t have them & two roll therefore would be acceptable. Bottle trolley: If you want a stepped voltage machine to be portable, you’ll need one. If you have a full size industrial cylinder check that the running gear & cylinder rack are man enough.
The weight of an angle grinder is important too – anything between 1.5 and 2.5 kg is acceptable for a 115 mm or 125 mm angle grinder. And don’t forget about accessories – budget angle grinders in particular are usually packaged with extra cutting or grinding wheels. I’ve tested out the best angle grinders, from high-tech cordless angle grinders to budget-friendly basic ones, so you don’t have to. Read on to see what I discovered… Makita is one of the most respected tool brands around, and the GA4530R is an excellent example of a professional-quality angle grinder. It’s easy to use, not too heavy and it’s built like a tank. There’s a good reason why builders and savvy DIYers across the world trust Makita. Their build quality and attention to detail are second to none. This angle grinder has a large rubberised rear grip and a tough power cable. I can see it lasting for a long time, even on a building site.
Some tips 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.

GPPH’s tables offer an incredibly stable and sturdy construction. The table top is made from 15MM thick material, this is outstanding when compared to the typical 6MM – 10MM that is usually used on lower end welding tables. In addition to this, the steel used is S355J2+N grade that is carefully selected. The steel is also unpickled so as to prevent the material becoming bright and causing arc to flash bounce off the table making the working conditions difficult for the welder. Finally, the tables are not coated with paint as it can make the surface difficult to conduct. They are coated with an oil based preparation which protects the tables during transport. Anti spatter is suggested.

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.
