Amazing TUNGSTEN. I never have to switch it out when I weld something new and the arc always strikes perfectly. I am on this for the rest of my welding days!!

Some of the best large tungsten I have ever used. I am a definite believer from now on. And they set me up with a Net account in a couple of minutes. A wonderful experience.

We started using the ArcTime after we had some major quality issues with our tungsten supply. One of the challenges of being a government entity is the material is supplied for a variety of reasons, and most times quality is not one of them! We were using the 1.5% and 2% Lanthanated material, and it varied in performance and each supplier had a box with a different label on it which did not sit well with our welding shop instructor. We tested the ArcTime material and were very pleased with the look of the material, the supporting documentation and most importantly the performance. We do maintenance welds on Aluminum ship hulls – the ArcTime hybrid tungsten out performs all other materials, and saves us a lot of headaches. Now we can focus on welding!

Try it for yourself, then tell us what YOU think!

A lot of folks wonder what the difference between inexpensive import TIG Torches you see being sold at a lot of online welding suppliers, and the quality name brand– and yes, more expensive TIG torches such as the ones carried by distributors like Arc-Zone.com.

One of the biggest differences between brand-name and no-name torches is the materials used in manufacturing…

Copper
There is tellurium copper, which is very basic plumbing type copper and then there is leaded nickel copper which is a high conductive, high tensile strength copper alloy. This is important for two reasons, one it’s a better conductor, and two it is more durable, the TIG torch body threads last longer, collets don’t buckle and twist etc.

Silicone Rubber
Weldcraft changed the rules when they introduced the Silicone rubber molded TIG torch. Prior to that all torches were molded in a hard plastic material. Difficult to hold, impossible to bend and very susceptible to arcing out. You would think that silicone rubbers are all the same, but again there is a big difference in the material quality, and how much heat it takes before it begins to breakdown, and how well it is bonded to the copper TIG torch body. Materials and preparation are key here and come back to the basics of production standards
(more…)

I wrote a post a few weeks ago and made some pretty pointed comments about some of the manufacturers/re-sellers in the TIG business. I immediately got a letter from an Attorney claiming that the comments were out of line and not necessary. While I understand the concern, what I was trying to say is that many companies have no ENGINEERING expertise and no Electrical or Mechanical Engineer on staff.

It’s not like back in the 1970s when you could simply tinker with a few parts and market it as better– who would know. Today it’s different. Equipment has improved greatly; machines are far more sophisticated and complex electronically.

In business you have to make many choices — As you know we chose to tie our wagon to the Weldcraft® brand of TIG torches. I have an extensive history with that company and was instrumental in establishing Weldcraft® as the undisputed world-wide leader in TIG and for a short time Plasma Arc Cutting torches. A lot has changed since I left the company: new ownership, factory relocation, management changes…. Weldcraft has gone from a business run out of one guy’s garage to being a part of ITW, a publicly traded, well-respected multi-national corporation.

That brings me to my point. What’s the Difference?

We just received a shipment of the new Weldcraft WP series TIG torches and they are nice. They use a new, patented scalloped or textured ergo style torch body with improved design features. You can’t miss them, they are Red!

Another huge differentiator is the collateral material included with each New Weldcraft TIG Torch. The information is very well laid out and includes great technical information, hook-up instructions, welding techniques, welding symbols, duty-cycle ratings, grounding information, amperage ratings for different tungsten sizes and more. This kind of information comes from having a full bank of engineers on staff, and sharing technical information with sister companies like Miller Electric.

When you compare what you get from other companies it is clear that Weldcraft® is on solid ground and back on their way to being the TIG Welders Choice™

It’s all about who builds them! Sure there are many differences in materials and workmanship, and I’ll talk about those in future posts, but the bottom line is you want to buy from a company that actually knows something about what they are making or selling, how and what it is used for, and what it’s going to connect to.

If you look at the industry there are many companies that sell TIG torches — SouthWeld, ProFax, American Torch Tip, Thermacut, Abicor Binzel, CNI, Kuton, MasterWeld, Radnor, Best Welds, Anchor brand, CM Industries etc. etc.

What’s the Difference?

Most of those companies buy from the same importer that buys from the lowest cost supplier in China. We have been there and have seen first hand the so-called factories where these items are built. That’s fine for some things, but as we have seen more and more in the consumer products market, these products are not made to any standards.

Remember these are electrical components that deliver power from your expensive TIG welding machine to the part you want to weld. Most of these companies offer Zero innovation, 100% reverse engineered product– and I’m being kind. The majority of those parts are built to no specifications of any kind — they receive a sample part and they reproduce it.

No matter what you hear “parts are not parts” there is a huge difference, starting with materials: Tellurium copper versus leaded nickel copper, silicone rubber versus hard plastic and even the kind of teflon that is used for insulating gaskets. And then there’s the workmanship: soldering versus brazing, how the cables are made, etc.

One of the things we pride ourselves on at Arc-Zone.com is offering only the best quality TIG Torches.

by Jim Watson 

A variety of tungsten electrodes are available from resellers who put their label on it and offer it for sale.  Often this material is considered a commodity and is bought at the lowest price.  That’s great for the Purchasing Department’s bottom line, not so good for a welding department’s quality and productivity

While it’s true that most of the tungsten electrodes on the market today come from China (in fact most all the tungsten ore has come from China for years) not all manufacturers are the same – not even close!

Let’s take a closer look at some of the problems we’ve seen with these cheap “reverse engineered” tungsten electrodes:

Varying Diameter – without strict adherence to specifications, the tungsten electrode diameter can vary causing problems with tungsten gripping in the collet/collet body of your TIG torch or your tungsten sharpener.

Bent Electrodes – especially with 1/16” and smaller diameter tungsten electrodes.  This can cause problems with arc performance.  See photo below.

Inconsistent Finish – spotty texture and uneven ground finish indicates a total lack of production quality.  A poorly textured finish can also contribute to arc performance problems.

Flaking paint – tungsten electrodes are color-coded with a swab of paint on the end to distinguish one blend from another. When the paint flakes off, not only does it render the color-coding system useless, it can contaminate your weld.

That’s what you see, but what’s more important is the make up of the base material prior to extrusion.  Tungsten electrodes are produced by mixing chemical compounds raw tungsten and specific dopiants which make up each blend thoriated, lanthanated etc.  Consistent mixing, the extrusion process, and adherence to documented procedures is the real key to a high-quality end product.

We field more technical calls from customers with poor weld quality, and inferior tungsten performance than all other products, well other than junk gas lenses…  more on that later.

 Bottom line, when considering tungsten electrodes — you get what you pay for.

NOTE:  Reverse engineer
to disassemble and examine or analyze in detail (as aproduct or device) to discover the concepts involved in manufacture usually in order to rpoduce something similar.  Similar. Not the same….
