Auto-darkening screens use a combination of light-sensing technology and auto-darkening LCD screens that modulate based on the light coming in. They can react nearly instantly to an arc and clear up almost as quickly when the arc is over, so they’re very reactive to your operations. The downside, of course, is that these are much more expensive (and tend to have smaller viewports) than fixed-darkening shades. Auto-darkening helmets have a “reaction time” measurement as well. This can be measured in fractions of a second, 1/3600th to 1/25000th of a second; the faster the reaction, the better. The longer it takes to transition, the more harmful light makes it to your eyes, and the more damage can build up over time.

Welding is a vital process in many industries, but it involves significant hazards that can pose risks to health and safety. Understanding and implementing rigorous safety protocols is not only a responsibility, it’s an essential part of every welder’s daily routine. These measures help prevent accidents, reduce injury risks, and ensure a safer workplace for everyone involved. Welders face various dangers including burns from hot metal and sparks, eye damage from ultraviolet and infrared rays emitted during welding, respiratory issues from inhaling fumes and gases, and risks of electric shock. Each hazard requires specific precautions to protect the health and safety of welders.
The overall temperature of the materials will vary depending on the kind of fusion as well. Arc welding, harnessing the power of lightning, produces very high temperatures. Depending on the metals being fused, this temperature can range anywhere from 2,000 to 3,500 Celsius and, in some cases, even higher. Brazing is a lower temperature application and, as it doesn’t melt the base materials, keeps heat just high enough to melt the filler and flux being used. This is generally in the range of 600 degrees C. Soldering needs even less heat. The melting point of solder is generally in the range of 90 to 450 C, and many soldering irons are generally set to the 300–350-degree range.
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.

A few tips on welding equipment, MIG and TIG welders, plasma cutters. MIG welders use a wire welding electrode on a spool that is fed automatically at a constant pre-selected speed. The arc, created by an electrical current between the base metal and the wire, melts the wire and joins it with the base, producing a high-strength weld with great appearance and little need for cleaning. MIG welding is clean, easy and can be used on thin or thicker plate metals. Similar to MIG welding, flux-cored arc welding (FCAW)* is a wire-feed process but differs in that self-shielded flux-cored welding does not require a shielding gas. Instead, flux-cored wire is used to shield the arc from contamination. This is a simple, efficient and effective welding approach, especially when welding outdoors, in windy conditions or on dirty materials. The process is widely used in construction because of its high welding speed and portability.

Although this is a regular drill press and not a magnetic drill press, you can also use this one for steel drilling. The motor has a rating of ½ HP and in order to change the drill speed for metal drilling, you have to change the belt and pulley combination setting to the slowest speed. As a drill press, the RIKON 30-120 does not have the best performance. The feeding wheel is not well made and is awkwardly situated. Your chances of getting the back of your fingers caught between the feeding wheel and the belt tensioner are quite high and it is very painful. The packaging of this drill press is poor as well. If you are looking for a tool that you can use for drilling steel exclusively, we recommend that you stick to magnetic drill presses. Regular drill presses can work great for wood, plastics, and steel, but they don’t have magnets and is impossible to use for vertical and overhead 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.
The Hobart Handler 140 is an excellent choice for beginner welders, which is why it’s probably the most popular welder on the market.

It’s suitable for a range of general repair tasks and projects like trailer frames, autobody repair and anything up to 1/4 inch thick. If you’re just getting into welding, you can’t go wrong with this little machine! What’s better is that it’s an absolute steal at under $500. See the full review here.
If you know that your new machine comes with a 2-year warranty, it can take a lot of the stress off your shoulders if your device suddenly stops working. If you can’t find a MIG welder with an appropriate warranty and the right features, it’s often a good idea to choose something that has spare parts which are easy to find. Try not to buy anything that’s made outside of the UK. The price range may be more affordable but the parts would be harder to source. Look for a spool gun so you can weld aluminium. If you plan on using your home welder to weld aluminium, then you’ll need a standard spool gun. Aluminium can quickly become damaged and tangled with a typical welding wire feed spool, so a spool gun will ensure that you can get the best results from your DIY work.

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.
UK market dive: Therefore, a metal inert gas welder is faster to learn for a totally novice welder. Buying one means having the vast majority of the welding tools you need sent to your door in one box. In general, they take less than an hour to set up and make for quite easy welding. Compared to the other common types of welding we have mentioned, the skill level of the welder is not nearly as important. Almost anyone can learn how to MIG weld with one of these machines after an hour or so of practice.
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.
Look for ways to create more efficiencies in the welding process. This includes examining such things as wire diameter, wire feed speed, voltage, travel speed, gas type, transfer mode, etc. For instance, if the shop is currently welding with a short arc process and a 75/25 blend of shielding gas, it may be more effective to switch to a different gas and a spray mode of transfer. Or, a change in process may be warranted based on the condition of the part. If there is oxide on the part, it may be easier to change to a process that will overcome contamination problems rather than try to clean each part before welding. Your welding supplier should be up to date on the latest technology and be able to advise you on new processes, machinery and consumables that can optimize welding at the shop. In some cases, it may be better to double bevel a joint to prepare it for welding rather than single bevel it. It is recommended to double bevel any material that is more than 3/4″ in thickness. Just this simple change in procedure can save quite a bit in weld metal. On a 3/4″ thick piece, a double bevel will use 1.45 lbs. per foot of weld metal while a single bevel will use 1.95 lbs. per foot.
