Valued Thermadyne Distributors:

We hope you will enjoy this issue of our Sales & Marketing News. This publication is dedicated to putting
a spotlight on new products, promotions, programs and people.

You will note that our cover proudly displays Victor Professional Edge Series regulator which will be
launched in September and available for orders in September as well. The product has an advanced design
and offers outstanding flow performance. And like everything that is sold under the brand Victor umbrella
it was developed with safety as a top priority. Not just Safe. Victor Safe.

The Victor Professional Edge Series regulator is an exciting product story, as are a number of other product
innovations in the works for our industry leading brands. If you have the opportunity to visit with us at
FABTECH AWS in Chicago, we’ll have this and a few other pieces of news to share. We’ll be located in
the North Hall at exhibit space 34046.

In the meantime, we hope you will not hesitate to contact your Thermadyne representative about Victor,
Thermal Dynamics, Stoody, Thermal Arc, Arcair, Tweco or TurboTorch. We are also happy to hear from
you via e-mail at marcom@thermadyne.com.

Shown here is a rendering of our planned FABTECH AWS exhibit space, which is still in development.
The mural backdrop shows a number of metal cutting and welding applications. Under each arch, we’ll
showcase a product spotlight area. Video will be running throughout the show with various product
features and highlights.

WARNING: THE GAS INDUSTRY IS COMING UNDER NEW REGULATION
The new regulation you get with the Victor Professional Edge Series regulator offers outstanding flow control. It’s
easy for a regulator to maintain good flow control when inlet pressures are high, but cylinder decay is inevitable.
A regulator needs to function well across an entire range of cylinder pressures. That’s exactly where The Victor
Professional Edge Series regulator outperforms the competition.


It’s easy to use. The Edge Series regulator comes
with gauges with enhanced high contrast graphics.
The regulators are color-coded for quick and
easy identification of gas type. They are better
positioned for hand/body position while adjusting
delivery pressure.
The advanced design of the Victor Professional Edge
Series regulator is the smallest, lightest and most
compact heavy duty regulator available on the market.
The design is innovative and unique and it is a better

“THE BEST IN THE
INduSTRY”
As a major equipment supplier to the scrapping industry,
Eddie Grosman knows what it takes to cut through the
most rugged materials. So when his customers need
help with heavy-duty scrap, he recommends the Victor
Bulldog torch.
“VICTOR BulldOg TORCHES ARE THE BEST SCRAP
TORCHES IN THE INduSTRY,” SAYS EddIE.
Along with a great torch, the key to superior cutting
performance is the right volume of oxygen supply.
“A lot of companies run into problems with portable
liquid oxygen bottles and their low output,” he says. Most
portable liquid oxygen bottles are limited to approximately
350 cubic ft. of output per hour. “We put an external
vaporizer on the bottle to boost the output to roughly
1,000 cubic ft. per hour, and that’s when the Bulldog
really tears through anything,” he says.
Grosman doesn’t just rely on Bulldog torches to make
the tough cuts. They’re also helping his business grow.
Eddie’s Welding Equipment is the largest distributor of
Victor Bulldog torches in the nation. He says, “We’ve seen
consistent growth each month since we began offering
Bulldog torches because they are the best.”

True professionals know that nothing can replace a Tweco MIG
gun. For decades, welding operators around the world have felt
the pride of owning one of the most trusted brands in the industry.
With a rich history of producing top quality professional guns like
the Spray Master and one of the most popular MIG guns of all time
– the No. 4 MIG, it’s easy to see why the Tweco name has become
synonymous with dependability and reliability. Nothing compares
to the genuine craftsmanship of a Tweco gun.

Visit www.twecotrust.com today.


VERY COOL, INDEED One of the key features of the Spray Master MIG
gun is how cool it operates in the most demanding
Spray Master MIG Guns from TWECO conditions. “The extended trigger on the handle keeps
my hand away from the heat of the arc especially
when we switch to flux cored wires,” reports Jason
Burns, one of DAE’s top welders.

The Spray Master handle is designed to stay cool, and
can increase overall productivity by not overheating,
or creating welder fatigue. It is also designed with
a superior Cablehoz rating that can handle higher
amperage ranges. This promotes better electrical flow,
which reduces the heat that can be generated from
poor connections or cable ratings.
Consumables such as contact tips are also a main
concern when welding in any environment. The
Spray Master utilizes super heavy duty contact
tips that can support up to 600 amps, and when
compared to standard consumables, the parts life can
be up to 10 times longer, due in part, by the fact that
the Spray Master has extra mass and toughness built
into the diffuser and nozzle.

L OUISVILLE, KY: DAE Industries, designs,
fabricates and installs aircraft engine stands,
docking and maintenance access stands, and aircraft
maintenance tooling. DAE has the manpower and
expertise to fulfill nearly any application that requires
aircraft work stands, docks, and engine stands from
engineering and design, construction, installation,
modification to relocation.
The company has 40 welding and fabrication stations,
and was looking for improvements in MIG gun
durability and consumable life. The Spray Master MIG
Gun from Tweco was the answer. Led by Thermadyne
District Manager Sean Norton, DAE was able to see
instant improvements from their existing MIG guns by
switching to the Tweco Spray Master.


“We have experienced a 60-70% increase in total
consumable life, which has created less downtime
when changing out parts,” says Fabrication Manager
Dennis Cook. (Dennis Cook is shown in photo on opposite page)

“Contact tip life has increased from 2-3 days to
nearly 3 weeks,” added Jason Burns, one of DAE’s
best welders.

The Spray Master MIG Gun is designed with comfort
and feel in mind. It has a natural curved handle that
fits well in most welders hands. Being very light
weight, the Spray Master is also very maneuverable.
With a conductor tube that can be rotated 360
degrees, and with several conductor tube angles to
choose from, the Spray Master can be configured
for nearly any application. Jason Burns also noted
that “Tweco has adapted the conductor tubes on
our Spray Masters, to create the perfect angle
for welding.”
DAE has been using the Spray Master for more than 6
months in full time production. It was critical to find a
solution that minimized production down time not only
from a welder fatigue and consumable point of view,
but from maintenance as well.
Dennis also shared that “Spray Master has proven to
be extremely dependable and tough with zero failures
to date, not even a trigger switch. As a matter of
fact, we haven’t even needed to replace any liners yet
either, the wire keeps feeding extremely smooth.”
The Tweco Spray Master MIG Gun was just what
the doctor ordered for DAE as they considered their
upgrade. It is keeping them running. Congratulations
on another Tweco MIG gun conversion success story.
A special Thanks to Thermadyne DM, Sean Norton and
Thermadyne Product Line Manager, Pete Anderson and DAE

Kyle is a self-employed welder and owner of K&K
Welding in Berlin, MA. He finds that free time is difficult
to come by. That’s likely because Kyle works primarily with
aluminum. “You can pick up steel welding pretty fast,” he
says. “But aluminum is a whole different animal. If you
can weld aluminum, it opens up a lot more doors.”

With his skill in such high demand, Kyle needs flexible
equipment that he can rely on to get the job done. That’s
why he loves his Thermal Arc Inverter Arc Welder. “When
the Thermadyne representative came to my door with this
little machine, I thought there was no way it could do what
I need it to,” he said.

The power and flexibility of the Thermal Arc Inverter Arc
Welder shocked him. “I welded a 4’x4’ aluminum plate,
