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

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.
