WHAT’S
NEW AT ARCON WELDING?
In addition to his sales and customer support duties, George
Bell is designing advertisements, submitting editorials for
trade magazines and is now publishing this E-publication. It
is available at your request. George is anxious to hear about
your ideas, questions and concerns.
ARCON’S
FEATURED WELDER
The Workhorse Tigweld 300ST
is a remarkable TIG/Stick welding machine which, unlike high-frequency
arc start machines, does not cause radio interference.
This interference can affect communication systems such as computers,
cell phones and televisions .This welder was specifically designed
for demanding TIG welding where the tungsten (wolfram) isn’t
allowed to touch the base metal and contaminate the weld. This
new Workhorse is a "no-nonsense", cost-effective machine
that uses capacitor discharge single pulse arc starting. The
Tigweld 300ST offers TIG and Stick welding current from
10 to 300 Amps @60% Duty Cycle in two current ranges. The new
machine is available for all domestic and international standard
single input voltages.
This little powerhouse offers big benefits! It produces a powerful
spark that penetrates through painted and rusty surfaces. It
features a built-in gas valve and adjustable gas pre-flow and
post-flow control. The arc is easy to strike with the spark
reaching a half-inch distance in argon gas. The 300ST’s
cooling fan doesn’t operate at less than 100Amps. This
greatly reduces the intake of dust into the weld. The Tigweld
300ST’s standard carbon arc gouging protection eliminates
harmful currents caused during arc gouging. The machine has
Smart Surge Control that reduces weld puddle agitation. This
eliminates a major cause of slag inclusions in the weld.
The Tigweld 300ST incorporates constant-arc power,
which means less dependency on a steady hand to achieve a great
weld. The constant-arc power makes "burn through"
almost impossible when increasing the arc length or welding
thin material. This means that you can forget about holding
a constant arc length, making TIG welding much easier .All of
the Workhorse family of inverter type welders offer unique features
not found on other brands. These include the SCR Inverter, constant-arc
power, and amazing durability .
The SCR inverter design is used in all Workhorse welders. Research
indicated SCR inverter failures are far less than IGBT inverters.
In field-testing, The Workhorse design proved to be
100 times more durable in welding applications! This multiplies
the life of the machine and greatly reduces costly downtime.
The rugged Workhorse fiberglass enclosure handles tough work
environments and "dragging skids" underneath are standard.
This 19.5" long x 17.9" high x 10.5" wide machine
stores and stacks easily. ARCON offers a Seahorse corrosion-resistant
version for harsh environments. Although ARCON’s welders
are considered to be superior in handling over-voltages and
spikes, the Warhorse option is available for excessive voltage
surges and spikes in "dirty voltage" environments.
All ARCON welders comply with UL 551 and equivalent CE/IEC60974-1
safety standards and come with Arcon Welding’s three-year
limited warranty. Visit ARCON online at www.arconweld.com for
our complete line of brutally rugged and dependable welders

MEET OUR DISTRIBUTORS
ARCON was pleased to be an exhibitor at Lee’s Gas Supplies,
Inc. in Elkridge and Baltimore Maryland on May 14 th and 15
th . The food and Kettle Corn was delicious (catered by The
Terrible Grill) and the weather was perfect for the open house.
Lee’s Gas Supplies is owned by Valley National Gases and
has been serving the Baltimore metropolitan area since1947.
Lee’s supplies compressed and liquid gases, dry ice and
welding equipment and supplies. The staff is friendly and knowledgeable
at Lee’s, and ARCON is especially grateful to Account
Manager Chris Binaut for his assistance that enabled us to demonstrate
both the Arc-Starter TIG and Stud welding machines. Those in
attendance found the day informative and many showed great interest
in the equipment on display. Customers in the Baltimore Maryland
area can contact Lee’s Gas Supplies at 410 631-7040 or
in the Elkridge area at 410-799-1114.
APPLICATIONS
AND EQUIPMENT
USING THE WORKHORSE STICK/TIG WELDER IN THE SHIPYARD
ARCON has many Workhorse 300S Stick/TIG welders being used to
weld aluminum in various shipyards using voltage-sensing wire
feeders. 3/64" aluminum wire can be used with wire feeders
such as Miller’s Suitcase 8VS or Lincoln’s LN-25
with a suitable MIG gun. The guns we hear the most about are
Tweco’s M412-4535 and M415-4535. Bill Strate of Strate
Welding in Jacksonville Florida says this is an ideal setup
to weld "hot and fast, making as few passes as possible".
ASK
THE TECH
Question: Some advertising states that higher
inverter frequency equals smoother welding. Is this true?
Answer: The theory behind this is that the
ripple in power caused by the inverter frequency will make the
weld puddle temperature change. The current in the arc has a
higher ripple frequency with a higher inverter frequency, which
would cause less temperature variation.
The fact is that the weld puddle has a thermal time constant
of approximately one-second. The Workhorse has an inverter frequency
of 2,000 HZ corresponding to 0.0005 second, which makes its
variation 20,000 times faster than the weld puddle’s thermal
constant.
