New Optrel e684 Helmet Allows Welders to â€śSet It and Forget Itâ€ť with Fully Automated Shade Level Protection
Adaptive Shade Autopilot ADF technology automatically adjusts shade level to the weldersâ€™ parameters in full high definition viewing
EAST GREENWICH, RHODE ISLAND â€“ Optrel, the global innovator of autodarkening filter technology for welding helmets, brings ADF lens and optical technology to the next level. The new optrel e684 is the only welding helmet with an ADF lens that fully automates protection through its Adaptive Shade Autopilot technology, automatically adjusting its shade level as the welder works â€“ and in full high definition viewing. This new level of clarity and automation not only keeps welders better protected, it enables them to perform their job more efficiently, with greater accuracy and precision every time.Read More
Using Lift Start Like a Pro
Written by Weld.com
If you hate using anything other than high frequency arc initiation in your TIG welding, you are not alone. Everyone has gotten into that position where they canâ€™t (or donâ€™t want to) use high frequency starts due to the interference it can create with some electronics or you are somewhere where you are not allowed to use it. The problem is, as welders, we have become so accustom to using HF to initiate our arc that many of us are no longer proficient at using the lift start function on our TIG welders.Read More
Pipe Welding: Three Commonly Used Processes
Written by Alexander Barth
Pipe welding is an important trade which has revolutionized modern society. There are several different categories including pulsed TIG, stick and MIG welding. Of course, this skill takes a good amount of time to master and welders need to be certified based upon levels of expertise. In terms of pipeline welding and even domestic purposes, all welding processes need the use of electricity to generate the necessary heat to successfully bond two sections of pipe. Also, equipment such as pipe clamps and pipe stands are required to provide a safe and stable platform during the entire process. So, what are the basic forms of welding that are used?
As the name hints, this process involves a rod that is coated with a metal powder which acts as a shield from oxygen during the burn process. This is the most common type and it can be somewhat difficult because the welder is not able to see the weld due to the fact that it will be covered with slag. This excess material must be broken away after the weld is complete.
Metal Inert Gas (MIG) Welding:
This technique employs a wire spool which feeds this material to the intended pipe joint. Also, a pump supplies inert gas to the welding handle. This gas is again intended to protect the weld from any ambient air. While MIG welding is considered to be easier than stick welding, setting up the required pipe welding equipment can be difficult and due to the potential for windy conditions, this is generally not used for exterior tasks.

Tungsten Inert Gas (TIG) Welding:
This method uses a torch which contains gas within its interior. A permanent tungsten rod heats the metal of the pipe while a "filler" metal is held in another hand. This metal is fed into the joint as is needed. The benefits here are that a greater degree of control can be enjoyed and the weld can immediately be seen. However, this two-hand process can be challenging for novices and TIG welding is therefore considered to be one of the most difficult forms to master. (See more on TIG Welding Pipe)
These are some of the most basic features of modern welding processes that are used. In many respects, welding is as much of an art form as it is a science. Experienced welders boast decades of experience in this novel, challenging and potentially lucrative industry.

GMAW or GTAW: How to Choose the Right Welding Process
Written by Weld.com
There are a lot of different choices out there when it comes to welding. A lot of home hobbyists (or Weekend Warriors) have trouble deciding which process to use, especially guys that are new to welding. When it comes to welding in your garage or in home use, there are basically four processes that most welders consider these days; GMAW, GTAW, SMAW or FCAW. Each of these processes have advantages and disadvantages and should be considered for different reasons. GMAW and GTAW have become the two prominent choices for home use these days (see our video on the differences between MIG and TIG for more information). In this article, we will go over what you need to get started with each process and some reasons why you might choose one over the other.
