This guide to fume extraction systems will help you understand more about regulatory requirements, benefits of fume exhaust systems, types of fume ventilation systems, and some important considerations when selecting a fume extraction or fume exhaust system. Local exhaust systems remove aerial contaminants at or near the source. This offers some of the greatest protection as toxic elements are captured before they can mix with a worker’s breathing zone. This is the preferred method of fume removal if the fumes are a serious health risk, heating and cooling costs are a concern, and if there are a limited number of emission sources. Read even more information at Welding Table.
Being exposed to fumes generated by welding or thermally generated particles is a significant health and safety concern for manufacturers. The potential health hazards span from minor illnesses like a sore throat and eye irritation to more severe conditions like metal fume fever, and can even extend to long-term or fatal illnesses such as cancer. In 2019, International Agency of Research classified weld fume as a known carcinogen. Unregulated dust and fumes also have negative effects on factories efficiency. Dust and particles arises from metalworking procceses can penetrate machinery or electrical enclosures, leading to operational downtimes and reduced efficiency.
Welding helmets are a crucial aspect of personal protective equipment for any welding operator. They protect from the intense glare and eyesight-damaging light from a welding arc, fumes from the welding operation itself, stray sparks that can burn, and so much more. They’re an essential part of any welder’s kit, and they’re a purchase that can last for decades if well-maintained, so it’s important to put some thought into which helmet you’re buying. So, what should you look for? What factors should you evaluate when you’re exploring welding helmets? Here’s our guide. While there’s a lot to consider, one thing is certain: you need a helmet whenever you’re welding. The only possible exception is if you’re using CNC welding machines, and they’re enclosed in their own darkening shades. Even then, it can be beneficial to keep a helmet on hand.
Implementing physical barriers and clear signage around welding areas helps to alert other workers and visitors to the potential dangers and restricts access to authorized personnel only. Barriers and signs serve as preventive measures to protect non-welders from accidental exposure to sparks, UV radiation, and other hazards associated with active welding sites. Beyond preventive safety measures, welders and all workshop personnel should be trained in emergency response protocols. This includes knowing how to handle welding accidents, such as burns or exposures to toxic fumes. Effective emergency response training ensures that all employees are prepared to act quickly and efficiently in case of an accident, which can minimize injuries and potentially save lives.
The strength of a joint can be imperative or a non-factor, depending on the purpose of the welding process. Arc welding joints are generally extremely strong unless they are not performed properly. The resulting strength of the material is often at least as strong as the base materials and, in many cases, actually stronger. Brazing joints are not structural in general, but they can bear some load. In plumbing, for example, water hammering can be an issue in some systems, so the joints need to be able to stand up to that kind of force. They are not structural, however, so there is a maximum load they can bear. Soldering joints are almost never structural in any way, and the forces they handle are more electrical than tensile, linear, or shear. As such, they are not very strong, but they don’t need to be. There should, ideally, be next to no force put on them.
The gas tungsten arc welding (GTAW) process creates accurate and high-quality welds with great penetration making it suitable for several applications, such as aerospace and automotive industries. While TIG welding has a steeper learning curve than MIG welding, the many adjustable features and functions of a TIG welder make it a very versatile process. Shielded metal arc welding (SMAW) also known as manual metal arc welding (MMAW/MMA) or just stick welding, uses a consumable flux-coated metal electrode to join metals. As we strike the electrode with the base metal, it creates an arc that melts down the materials in the weld pool. The flux releases a shielding gas to protect the weld metal from contamination. Slag deposits are removed after the cooling process using common shop tools such as a wire brush.
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.
Angle grinders are formidable tools and need plenty of power to spin cutting or grinding discs at high velocity. Look for corded angle grinders that spin between 11,000-12,000 rpm or cordless angle grinders that spin between 7,500-9,000 rpm. The best angle grinder should be powered by a 700W motor at minimum if corded or, if cordless, an 18V battery that has a capacity of at least 4Ah. The grinding wheel diameter on most angle grinders is usually 115-125 mm, although heavy-duty angle grinders can accommodate grinding tools over twice that size. Noise and vibration levels are important aspects to consider with this type of power tool. Often the best angle grinders are the least noisy with lower vibration levels. This is especially so with cordless versions with brushless motors but they are more expensive, particularly if you include the cost of a battery and charger.
The Hobart Ironman 240 is the updated version to the Ironman 230 that recently has been discontinued. The 240 is a well-reviewed welder that delivers a wide range of power from 30 to 280 amps in a heavy-duty American-made chassis. Hobart equips the Ironman series with its “soft arc” technology for an easier striking, more spatter-free arc. If you are looking to weld aluminum, then like most of their MIG welders, they offer the package with a SpoolRunner 200 spool gun found here, for a few hundred extra bucks. This is a full-sized platform, offering a 15-foot gun connection and able to load a 44-pound spool of wire. Hobart backs the Ironman 240 with a strong five-year limited warranty. The power regulator has 12 notch settings for easy feel when setting the power level with gloves. This power regulator knob seems to be a problem for some users who have reported issues with the knob rotating freely and not changing the power setting. The only downside to this model is that it is unable to run directly off of a generator as it causes problems with the SCR firing timing of the welder. This makes it a bit less portable than some other welders, but nothing you can’t work around. Overall, this is a quality industrial-grade welder which is ideal for farm work which has been compared to Miller 252 – just without the digital screens and a few other features that most people wouldn’t need, but costs a lot less making it excellent value for the money.
A few 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.
120V Input Power and 155 CFM Airflow. The machine requires 120V input power to generate 155 CFM airflow. You can adjust the airflow from 20 different settings as you need. It can provide support to 2 other operators at a time if you just install a second arm. 3-stage Filter and Suitable for Benchtop Soldering. The machine can be operated with a remote wirelessly, which makes it extremely useful. The 3-stage filter comes with Carbon, HEPA, and pre-filter, which I found to be effective for any welding work. At 50% motor speed, it generates 53 dBA sounds and produces only 63 dBA sounds at 100% motor speed. PACE Arm-Evac 150 can be used for any sort of benchtop soldering, industrial solvents, and lasers. It’s the best portable weld fume extractor for medium-level welding tasks.

The Lincoln EasyMIG 180 is a well-built welder that’s reliable and will serve a range of light fabrication and workshop projects. Its power input is 230V but it doesn’t have the power of the Hobart 190. This is a great entry level 230V welder that will give you quality welds. It won’t tackle thicker metal but this will do the job for most hobby welders. It’s a great choice for a hobbyist if you have a convenient 230V power outlet.
Additionally, like in any kind of arc welding, if you’re handling projects that are going to produce high heat and take a long time to finish, then you’ll need a welder with an internal cooling system to help you to avoid any issues with over-heating. To find out exactly how long your welder can run for, look at its duty cycle. As a general rule of thumb, a cheaper machine will often have a shorter duty cycle, which means that they’re not well-suited to welding thicker metals. There are man welding metalplenty of additional issues to consider when choosing your MIG welder. For instance, you might want to make sure that maintaining and repairing your new device is simple, particularly if you plan on using the welder for work or professional purposes. Discover extra details at here.
The people behind Display4top market this particular model as a professional MIG welder and we can’t say that they make a poor case in that regard. For one, its duty cycle is definitely up there. With its 48A rated output, the model is able to work for 6 minutes straight before overheating. It comes equipped with a variable wire speed control trigger, so you’ll be able to efficiently work with different metals. There are two power settings and an Ampere knob, further making the versatility case. More importantly, the model is as durable as they come. The forced air cooling system keeps the temperature at a nice, practical level. On top of that, the welder incorporates a thermal overload protection system that will be able to pick up the former’s slack in case it fails to do its job.
UK market look: Forney Industries is an American company that was founded in 1932. Forney’s 309 140 is affordable and able to weld many metals. As you’ll see below, its duty cycle is hardier than most, so you can work for much longer without breaks. It is about the same price is the Hobart 500559 Handler 140, but you’ll that the Forney is less suitable for any heavy-duty welding projects you might want to commit to. Therefore, the Forney is ideal for household use, provided that the use isn’t too demanding. It welds up to ¼ inches and includes flux core. It is capable of welding mild steel, stainless steel, aluminum, and cast iron. The Forney is able to use 4 inch and 8 inch wire spools. The cast aluminum wire feeding system ensures that the wire won’t tangle as much while it’s fed through.
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.
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.
