A larger viewing area gives you a better view of the whole of a weld, along with details of the welding pool, the arc itself, and the workpiece. These are better for larger projects and projects where you need to adapt on the fly. Other welding helmets have much smaller viewports. These smaller ports are more restrictive to your vision, which means things outside the direct line of sight can be excluded. In particular, if you have a dangerous environment, and a spark sets off a fire nearby, you might not notice right away. Ideally, you have a proper environment and other PPE set up so you don’t encounter this kind of problem, though. In general, the larger the viewport, the less likely it is to have advanced technology like auto-darkening because that tech is more expensive the larger it gets. See additional details on Fume Extraction.
Welding can easily ignite flammable materials due to sparks and hot equipment. It is essential to keep the welding area clear of all flammable materials, including oils, solvents, and combustible debris. Purpose: implementing strict fire safety protocols helps prevent fires, protecting both personnel and facilities. Fire fighting equipment like extinguishers should be readily available, and all staff must know how to use them effectively. Welding equipment should be properly grounded, and all electrical connections must be secure to prevent shocks. Regular inspections of equipment for damaged cords and improper connections are mandatory.
Soldering is another process used to join materials. In contrast to the other two, it’s a comparatively low-temperature process. A bonding material – the solder itself – is melted and used to adhere two pieces of material together. Soldering is extremely common in electronics, as it creates an electrical joint as well as a physical connection. It does not melt the base materials and, in a way, acts more like an adhesive than a fusion process. Soldering, like brazing, can be used in some situations where capillary action pulls the filler material into a gap in a joint. It also uses flux to ensure the purity and strength of the resulting connection. The joint that results from soldering is not as strong as the joint you get out of brazing or welding. The comparative softness of the solder, the fact that the base materials are not melted or fused, and the general lower melting point of the solder means it is not suitable for permanent or high-strength purposes. Most soldering is done in electronics, though it can also be used for non-structural joints in things like automotive radiators.
Arc welding includes some of the most well-known welding processes and these are most likely what come to mind when visualising the welding process in general. In these processes, an electric arc generates heat between the electrode and the metal to be welded. The electrode may be consumable or non-consumable, and its power source can vary from alternating (AC) to direct current (DC). Gas metal arc welding (GMAW), also known as MIG/MAG welding (metal inert gas/metal active gas), uses a continuous wire electrode fed through a welding gun. As the electric arc melts the electrode wire it is then fused along with the base metals in the weld pool.
How to pick a welder tips: Stepped voltage or synergic: Synergic MIG’s have the edge when you’re welding stainless & aluminium as they are pre-programmed, easy to set up & portable. They also provide a better weld characteristic and so give cleaner weld bead with less/no spatter. Inverters: Considerably smaller and lighter and so ideal for site work. All inverters are stepless and so have infinite control. Also cheaper to run power wise. Budget: How much welding are you going to undertake? Gear your purchasing decision around the jobs you will be working on the most. Polarity changeover; A lot of welders at the light industrial end will to be able weld with gasless flux cored MIG wire. Is the switchover easy on the machine you’re considering. Availability of spares & after sales service: Ask where the machine is actually made. Even the more recognised brands largely outsource their production, which can lead to quality and after sales issues with lack of continuity of supply for spares.
US tool brand DeWalt are known for making the best angle grinders, and the DCG405N is a step above the competition. Cutting the cord once and for all, this is a powerful grinder that makes use of DeWalt’s excellent XR battery system. This Dewalt angle grinder is not just a powerful cordless grinder though. The grip shape is supremely comfortable, and the whole unit weighs just 1 kg without the battery installed. You can lock-off the power switch when you need to get the grinder into awkward spots as well. This brushless angle grinder also features a host of clever safety features. I like the no-volt release to prevent accidental start-ups when a new battery is installed. The electronic brake and clutch are essential for safe operation too. The 18V brushless motor is ideal for battery use. It can make 69 cuts in ½” steel rebar when used with a 5.0 Ah battery. It doesn’t come with any batteries or one of DeWalt’s excellent TSTAK cases though, which is the case with bare power tools.
This is a professional MIG welder by Lincoln Electric with brass-to-brass connections, solid metal wire drive and a 220v / 240 volt input. Every feature is of professional quality. The case is much thicker metal than the Chinese machines, the circuit board is enclosed and it uses stainless steel hinges. These details matter when you put food on the table with your welder. With a welding range between 30 and 180 amps, the Easy MIG 180 can weld on everything from thin sheet metal on a car grille all the way up to frame modifications on the same vehicle, including metal up to ½-inch thick. At 130 amps, the duty cycle is 30 percent, making it unlikely you’d ever reach the point for most jobs where the automatic thermal shutoff kicks in. The Easy MIG 180 comes with a Harris regulator and the gun has a 10-foot connection. Lincoln Electric has an arc-starting technology that’s almost completely spatter-free, giving you time to dial in just the right settings for the task at hand. Lincoln includes both gasless and MIG nozzles, backing the Easy MIG 180 with a 3-year warranty.
Several advices about welding equipment, MIG and TIG welders, plasma cutters. Welders with a higher power output can work with thicker metals, but higher voltage welders will require special power supply set ups—either generators or appropriate power outlets. A welder with lower voltage in the 100’s will not be able to handle heavy duty jobs, but it can be plugged in and operated from any outlet. Any welder with power over 200 cannot run off a typical power outlet and will naturally cost more to run. In addition, welders will either run an alternating current (AC) that reverses itself at regular intervals or a direct current (DC) that flows in one direction and does not reverse itself. DC offers a steady rate of energy that leads to hotter temperatures and deeper weld penetration. AC welders usually cost less than DC welders, but the available electrodes are far more limited for AC. In fact, DC welders are more costly but remain popular because their higher power offers a wider selection of electrodes and a number of working advantages such as: simple arc striking, better penetration, and improved control. Welders who expect to work on a wide variety of projects may want to consider an AC/DC combination welder.

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. This thing is solidly built and is a step above many of the other 140A welders. The arc runs smooth and produces great results. 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.
It’s also worth looking into how your welder will handle things like short-circuiting. If a short circuit issue occurs while you’re welding, you don’t want a surge of power to ruin your work. Fortunately, there are many welding companies that implement strategies in their devices to eliminate the risks of short circuits. To choose the correct portability, size and weight for your welder, you’ll need to think about what you’ll need the machine for. If you’re going to be carrying it around a lot, then you need something that’s going to be highly portable and lightweight. Just make sure that a reduction in weight doesn’t mean that you end up compromising on power or performance. Read additional details at weldingsuppliesdirect.co.uk.
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.

The Goplus is able to weld steel and iron at below ¼ inches thickness.
Important Industrial Gas Cylinder Safety Guidelines to Keep in Mind: Acetylene and oxygen are two industrial gases widely used across various industries. The cylinders accommodating these gases are designed with user’s safety in mind. However, that is not enough to ensure optimum safety in an industrial facility. The following factors will help ensure the same: Understand the Cylinder Properly: A personnel should be familiar with the potential risks and hazards associated with compressed gases while handling them. It is important to understand the properties of the gas filled within such as toxicity, flammability limits, and toxicity – Threshold Limit Value (TLV). Also, it is important to understand the hazards posed by gas at low temperature, high pressure or due to the physical state of the gas – non-liquefied or liquefied, etc. A personnel should read the contents of the label on the cylinder. If the label is missing or not easily readable, then the cylinder should not be used. In addition to improving a personnel’s understanding on oxygen cylinder safety or acetylene cylinder safety, he should be administered a proper plant safety training.
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.
