What is Welding? Welding is the most efficient and economical method to date that is used to join metals permanently. It is the only way of joining two or more pieces of metal to make them act as a single piece both in shape and strength
Guidelines For Ac Dc Welders Welding is the process by which two metals or materials are joined together. The welding is generally done by arc welding. This process uses AC or DC current. Arc welding is used in welding most materials and can be done in shops, farms, garages and large maintenance departments in different factories. This is used for fabrication, repair and for educational programs. In arc welding, a welding power supply is used to create an electric arc between the base material and the electrode, to melt metals […]
Pulsed MIG May Solve Aluminum Fabrication Problems — Q&A Q: What’s the difference between spray transfer and pulsed spray transfer? A: Pulsed spray transfer, commonly called pulsed MIG, puts less heat into the work yet maintains many benefits of spray transfer, such as good fusion, high deposition rates and/or fast travel speeds. In pulsed spray transfer, the power source switches between a high peak current and a low background current. The peak current pinches off a spray transfer droplet and propels it toward the weldment. The background current maintains […]
Explain welding? Easy and hard so lets start with the easy. Welding is simply the melting of two adjacent metalic surfaces together such that the molecular structure of each piece intertwines as if it were one contiguous piece of metal. Well that is accoring to Poindexter, at a macro level it is simply melting two bits of metal together. On a more complex level welding then breaks into categories based on the type of process, be it TIG, Mig, Arc or Plasma welding. They all do the same as mentioned […]
I want to sell a welder, hey we match. get it? You want to buy a welder and I want to sell one, ok not so funny. Well a good place to start is to decide what type of welder you want to buy. You should start by researching the different types, arc welding, mig welding and tig welding for a start. Once you decide what type of welding will suit your need you can then create a table of features and cross reference this against the price. Call us […]
The dangers of el cheapo welding helmets and what can happen when you don’t invest in adequate protection. A flash burn is a painful inflammation of the cornea, which is the clear tissue that covers the front of the eye. A flash burn occurs when you are exposed to bright ultraviolet (UV) light. It can happen in all types of UV light but is a common problem among welders. That’s why it is sometimes called welder’s flash or arc eye. Flash burns are like sunburn in the eye and can […]
The Hypertherm Powermax30 plasma cutting system is the ultimate system for metal cutting up to 3/8” (10 mm). It’s designed and built for tough environments but is very compact and weighs only 20 pounds (9 kg). An optional carry case and shoulder strap make transporting the system even easier. Hand torch cut capacity Recommended: up to 1/4″ (6 mm) at cutting speeds of 33″ (838 mm) per minute Maximum: up to 3/8″ (10 mm) at cutting speeds of 15″ (381 mm) per minute Severance: up to 1/2″ (12 mm) at […]
Courtesy of DIY Welding UK, visit this article at their site. The main difference between cheap and expensive MIG welders is ease of use. For anyone new to welding that can equate to possibility of use. ——————————————————————————– It’s really difficult to put the differences into words. On the forum we have a section that helps people learn to MIG weld where people can post photos of their welds and ask for advice. It’s easy to tell from the photos which price range people have bought in. Those who have bought […]
Quest Engineering was established in the mid 90’s by a group of roadies that saw an opportunity in the emerging music industry. Over the years a brand was established proving Quest speakers as a work horse. Although the sound was great the look was, well, uninspiring. This is where the relationship began between manufacturer and designer, where from a single speaker re-design a complete design guide and product line redesign was undertaken. The following images captures some of the journey Michael Chijoff Portfolio

Arc [Arc Length] – The physical gap between the end of the electrode and the point where the arc makes contact with the base metal. Duty-cycle – As per EN/AS50974.1, the minutes out of a 10-minute period a welder / welding machine can be operated at maximum rated output. For example, a 60% duty cycle @ 300 Amps means that the welding machine can be used for 6 minutes (at 300 Amps) and then must be allowed to cool with the fan running for 4 minutes. This reduces the chance of […]
This question is one that is often put to us by prospective customers. Of course most people looking to buy a welder will first consider the purchase of a new welder over that of a second hand welder. There are several points to consider that may help alleviate the financial burden often associated with new welder purchases. 1. Consider the specific use of the welder 2. Consider how long you need it for 3. Consider if it is for daily weding or infrequent weekend welding In a society built on […]

WeldingTraining Personal protective equipment and clothing Dangers Gas welding The Welding Technology Institute of Australia (non-Queensland Government link) has issued a Technical Note on Health and Safety in Welding that provides practical advice on managing the risks associated with welding. TrainingWelders should be suitably trained and experienced for the work to be performed to minimise risks and hazards. When choosing someone to do welding work make sure the person has the necessary level of competence to do the work safely. Consider: •the person’s qualifications or statement of attainment; •if the […]
WHAT IS PLASMA CUTTING? Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process compressed air is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away […]
Tig Welding, Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors […]
Looking to buy a new welder, the best welder, the super best tig welder or just the super dooper best mig welder? Keep searching the net for that answer, it appears everyone has the best.
