I can’t believe what people do for their kids these days! Last weekend I took my daughter to a Birthday party for one of her pre-school buddies – it was at the San Diego Air & Space Museum in Balboa Park – the first thing you see at the entrance is a real SR71 Blackbird (pictured above) – more on that later.

Our private guided tour included a rocket making class, and each child got to fire their Alka Seltzer powered paper rockets! It was bitchen.

Kenneth from Pennsylvania asks Joe:

Do you have Weldcraft TIG Torch parts to fit a Miller DB20 water cooled TIG torch? Specifically a gas lens, collet and nozzle for .040? through .125″ diameter tungsten electrodes?

This question brings up a couple of points. First off, did you know that Miller and Weldcraft are related? Both are owned by the Illinois Tool Works (ITW). Currently all Miller TIG torches are sold as Weldcraft, taking advantage of the brand recognition of Weldcraft, a leader in the industry. Some earlier Miller torches were made by another company, but to quality standards.

Which leads me to point number two.

Most TIG torches parts are interchangeable. There are some exceptions, and certainly with some of the cheaper non-name brands you’ll find that the materials are not as good and the tolerances are, well, not tolerable…. But with quality brand names like CK, Diamondback, Lincoln, etc the parts should interchange.

If you google “Tony Welding” you’ll find a link to a cache of videos posted online and the opportunity to “attend” welding classes taught by Tony Marsden, a welding instructor at the Simi Valley Career Institute. Funded by the state of California, the Institute’s welding program is free, however, there is usually a waiting list.

An instructor for over 25 years, Tony has always used videos to supplement his instructions. “It did not occur to me to put them on google video until recently,” he says. There are 54 videos in total, covering everything from equipment and accessories, metal identification, welding symbols, tube bending, fabrication, and structural codes in the areas of Arc Welding, MIG, TIG and Oxy-Acetylene. These videos offer a way for students who can’t get into the program either by limits of space or geography, to learn from an instructor with over 40 years of welding experience and certifications in SMAW, FCAW, GMAW and GTAW.

The son of a general contractor, Tony was introduced to the construction industry and welding at an early age. Over the years he was told many times he would make a great teacher. When he was offered a position to teach part time, he accepted and part time soon led to full time. “I have always enjoyed sharing information,” he says.

Working at the largest and most comprehensive adult school in Ventura County, California has allowed Tony to share a lot of welding information. And place over 3000 students in good jobs over the last 25 years.

Doing business online we always wonder about the people on the other side of the computer screen, and we figured you were wondering too. So we put together this video to let you know what Arc-Zone.com is all about.

Let us know what you think! We had a lot of fun putting this together. More to come, so stay tuned!

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

Mark in Vermont asks:

I am running a Miller syncrowave 250 DX. Frequently welding cast aluminum, it pops and sizzles. I have always been looking for better cleaning techniques or a different tungsten to help get a stronger and prettier weld. There is always alot of black around the weld, and most times holes just “appear” in the weld. Any suggestions or tips to help?

That’s an interesting question — You can try a couple of things and see if it helps.

1. Use a gas lens collet body - this will improve the shield gas coverage, and allow you to run higher amperage while lowering the electrode and front-end parts operating temperature.

I spent the last weekend in Vegas and I’m not a gambler. I know that sounds weird as any entrepreneur is by nature a risk taker, but sitting at a slot machine pulling a silver handle (or these days, pressing a button) is not for me.

But Vegas is great! If you have not been there lately you should check it out. In addition to the gambling, they have shows, shopping and even some nearby recreation areas like Lake Mead, Las Vegas Motor Speedway… and Las Vegas is alive with construction projects. I was impressed by the scope of some of these projects, and best of all there is a lot of metal.

When we got in our room we were not happy with our view. We wanted to overlook the pool, so we asked for a different room. And when we got to our new digs, the bonus was that we could see the construction on the property next door. It was awesome, the project is the New City Center on the strip.

You could see all the action from the crane operators to the banks of welding machines, to the actual welders working from Sky Lift’s while they Stick welded the structural steel frame and architectural details. Of course there was a lot more welding going on inside the building as the entire core of the building requires a huge amount of welding and fabricating, from high-pressure pipe, HVAC, and on and on. I was thinking for young people this would be a great opportunity to travel, learn a valuable skill and make great money as a construction welder. It sure looked like fun to me!

EDITOR’S NOTE/ QUESTION: Is Joe Welder the only person who would be thrilled to have a room overlooking a massive construction project??

David from Peoria (Arizona!) wrote in and asked:

….about “spray arc transfer MIG.” I tried it with my Miller 8VS and Syncrowave 200 (on CC mode). It sounded like TIG, but I ruined a tip & nozzle. Is this type recommended “at home,” or do you need a bigger multi-processor power source, and what are the advantages?

I quickly replied:

I got a call today from Eric the maintenance foreman for the American Airlines Engine Repair Shop in Ft. Worth Texas. “Do you have the Monster nozzle in stock?” he asked.

When I said yes, he practically erupted with joy. “Man we have been looking all over for these things. They’re like gold around here.”

He told me they used to get a similar part but the quality was inconsistent, and the availability was too. He said, “We have a job to do, and we use these nozzles to TIG weld our Titanium and other special alloys that need repair.”

He went on to say that as the nozzles became scarce, they started making them in-house from a variety of materials — Phenolic, Ceramic and then settled on a CNC machined aluminum part that was ceramic coated. “The quality was great, but they take time to make and are expensive,” he said.

The Arc-Zone.com Monster nozzle will be a great replacement for them… and they can get on with the business they are in, welding specialized aerospace materials– not tools.

This is true of a lot of the quality purge gas accessories we sell at Arc-Zone. As a master fabricator you know you can build your own trail shield, or auxiliary gas welding nozzle…. but when you’re looking for consistency, and want to focus on your core business, it’s nice to have a supplier that can offer tools so you can Weld Like A Pro™.
