So what about darkening? A huge part of the purpose of a welding helmet is to be a nearly opaque viewscreen through which you can watch a weld without staring directly at the eyesight-destroying arc of your welding. Cheaper welding helmets have a fixed level of darkening. These are fine if you have a specific kind of welding you do all the time and can tailor your helmet to that kind of welding. If you do a variety of different welding operations, though, you’ll find that different materials and different processes generate arcs of different brightnesses. Your screen might be too dark for some and not dark enough for others. The other drawback to a fixed level of darkening in the shade is that you can’t see through it when there’s no bright spark in front of you. So, to check the state of your weld, you need to raise or lower the helmet so you can see it, then put it back in place to keep welding. This can be stressful, tedious, and even painful in rare cases. The alternative is to use an auto-darkening screen. Read extra information on Fume Extraction.
Consistent inspection and maintenance of welding equipment are critical to ensuring safety and functionality. This includes checking welding machines, cables, and torches for wear and tear, ensuring that all components are in good working condition. Purpose: Preventative maintenance not only helps in avoiding mechanical failures that can lead to accidents but also ensures optimal performance of welding equipment, contributing to safer and more efficient welding operations. Welding requires specific skills that can significantly impact the quality and safety of the work. Training programs and certifications ensure that welders have the necessary knowledge and skills to perform their tasks safely and effectively.
Temperature control is important in welding. Too hot, and the metals can change properties, melt through and burn away, or end up significantly weaker than the surrounding material. Too low, and the metals won’t melt enough to mix and join. Since molten metal is susceptible to chemical changes much more easily than solid metal, arc welding generally uses some form of shielding gas to protect the weld pool from oxygen and other inclusions. This may be generated through the use of flux that produces the gasses when it melts, or can be pumped in from a gas supply. What is Brazing? Brazing is similar to welding in two ways: it uses higher temperatures (though not as high as welding), and it joins two pieces of metal together with a filler material, filling the gap and providing a strong joint. The biggest difference is how it works. With brazing, the base materials are not melted at all. Instead, the two materials fit together with a minuscule gap between them. This gap is enough space so that capillary action can draw a liquid into that spacing. In this case, the liquid is a molten filler metal.
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.
How to pick a welder tips: Duty cycle: The advertised amperage of the machine offers a headline guide, but the duty cycle of the machine gives up the truth. Light industrial machine duty cycles can be as low as 20%, but more heavy duty MIG’s should range between 40-60%. If a 300amp MIG has 30% duty cycle for instance, it’s on the edge of acceptability. Duty cycle is determined by how many minutes out of 10, it can weld at 100%. Duty cycle testing: MIGS tested at 20 Degrees & 40 Degrees we consider good. (Beware any manufacturer who doesn’t quote an ambient temperature for testing) Manufacturer’s warranty: Always a great guide to quality. A three year warranty is good. Weld characteristics: Make sure the arc is smooth & suits your application. (Some machines are better suited at the low range and others at higher amperage range).
Power tool pioneers Bosch have been in the game since 1886. They certainly know a thing or two about making one of the best corded angle grinders on the market. I was amazed at the power output and precision you can achieve with the GWS 7-115 angle grinder. Starting off with the look and feel of this grinder, it’s surprisingly slimline and lightweight. It’s certainly easy to hold on to and weighs less than 2 kg. Bosch have made use of a clever 20° angle side handle as well for ultimate precision grinding. Making use of one of Bosch’s brilliant 720 Watt Champion motors, you know this is a tool that’s built to last. Everything is chunky and built for hard work. They’ve included a two-stage safety switch to avoid accidental starts, which is essential for any tool like this. The motor spins a 115 mm cutting disc up to an impressive 11,000 rpm. There’s a relatively low amount of vibration when in use as well. Just 6.5 m/s², which isn’t bad at all for corded grinders. I like the fact that Bosch have flattened the gear head. This reduces the overall size and makes it easy to get into tight spots. If you’re looking for one of the best angle grinders from one of the top names in the business, this is a great choice.
United Kingdom market look: 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.
Store the Cylinders Correctly: The cylinders should be stored in a dry, ventilated, and well-drained area, and away from ignitable and inflammable materials. Empty cylinders must be stored separately. OSHA also mandates the facility owners to store oxygen and fuel gas cylinders separately. The storage facilities should display proper warning signs for people regarding the dos and don’ts in the area where the cylinders are stacked. Always take care to store acetylene gas cylinders, as well as other compressed gas cylinders vertically. In addition to the above, the following should be practiced while handling the compressed gas cylinders. The cylinders feature tags, markings, or stencil marks for easy identification. Never deface or tamper these identification marks while using the cylinders.
In many shops, the operator has to go to a tool room or supply area for a new contact tip, coil of wire or other welding accessory. This takes valuable time away from the welding cell and slows down overall productivity. To improve the operating efficiency and minimize wasted time, companies should stock at least a limited supply of all necessary items near the welding station – this includes shielding gas, flux and wire. Another helpful productivity enhancing tip is to switch to larger spools of wire such as from 25 lb. spools to 44 or 60 lb. spools to even larger packages of 1,000 lb. reels or 1,000 lb. drums. A simple switch like this means less changeover time, which adds up over the weeks, months and years. Shops should also be on the lookout for shielding gas waste. A simple device called a surge turbine can be placed at the end of the gun to provide a digital readout of the gas surge and flow rate. If the surge rate is high, investing in a surge guard can reduce the pressure, eliminating gas surges and waste. Leaks in the gas delivery system can also create a potential loss of money. By looking at the amount of consumables purchased each year and then examining the total gas purchased, a company can determine if there is a significant loss. Welding manufacturers and distributors should be able to provide average utilization figures so that loss can be detected. If there is a loss suspected, one of the easiest ways to check for leaks is to shut off the gas delivery system over the weekend. Check the level on Friday evening and then again on Monday morning to determine if gas was used while the system was in shut down mode.

Some advices about welding equipment, MIG and TIG welders, plasma cutters. Stick Welding — If you learned to weld years ago, you likely learned using an arc welder. Stick welding for many years has been the most popular method for most home-shop welding needs. This process uses an electric current flowing from a gap between the metal and the welding stick, also known as an arc-welding electrode. Stick welding is an effective method for welding most alloys or joints and can be used indoors and outdoors or in drafty areas. It’s also the most economical welding method and provides the ability to create an effective bond on rusty or dirty metals. However, this method is limited to metals no thinner than 18-gauge, requires frequent rod changing, emits significant spatter and requires that welds be cleaned upon completion. Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It’s used for welding thicker metals of 1/16 inch or greater. These machines are a good choice for farmers, hobbyists and home maintenance chores.

Out of a huge product range of the Dirty Pro Tools, we have found a top-grade MIG welder that turned out to be so good that we have decided to add it to this shortlist. It is the tool for welding metalware of medium thickness with the output range from 50? to 60?, best for sheets up to 2 mm thick. In addition, a pretty powerful converter of this welder allows working for about 6 minutes at 50?. So, you’ll be able to weld thin pieces for a good while, and the fan will provide a decent cooling of the tool. However, when the MIG welder overheats, the red light will flash telling you to stop welding and make a pause. By the way, you can pick either of 4 available amperage settings and adjust the wire feeding speed for reliable and straight welds. We were pleased by the package that includes a face shield, a clipping hammer, a brush and a spool of welding wire, so you can start welding right after unpacking the unit. So, this Dirty Pro Tools welder is one of the most affordable models for people seeking a mid-power machine to weld fine metal sheets.
