The
Workhorse Robotic TIGweld 300ST-R
300
Amp GTAW/SMAW Inverter Power Source
This
product is primarily designed for TIG welding (GTAW) with an industrial
robot using a time-proven SCR-inverter type power supply. The Workhorse
power sources weigh 80 pounds, feature built-in circuit breaker, and provide
5-zones of thermal protection to make this machine ideal for integration
with an industrial robot using 240, 480, or 575 Volts AC for primary power.
- TIG
and Stick welding current from 10 - 400 Amperes in 2 ranges.
|
- Available
in dual primary voltage, 240V (single or three phase) and 480V.
Also available in single voltage 240V, 480V, 575V and 400V.
|
- Easy
to strike the arc. The spark jumps a 1/2" in argon gas and
stops when the TIG arc is established. The Workhorse 300ST even
has an inside adjustable pre flow and post flow.
|
- Carbon
arc gouging protection. (Circuit design that eliminates the harmful
currents caused during arc gouging has been added)
|
- Constant-arc-power
characteristic means less dependence on a steady hand to achieve
a good weld and reduces risk for electrode “sticking”.
The constant arc power characteristic is, if possible, even more
advantageous when TIG welding than when stick welding. The TIG
arc remains the same cylindrical shape without flaring out when
increasing the arc length. The constant power arc characteristic
makes burn-through almost impossible when increasing the arc length.
This means that you can forget about holding a constant arc length,
which makes TIG welding much easier.
|
- Corrosion
Resistance: All welders shipped after June 15, 2005 include Seahorse
protection to withstand corrosion in natural environments such
as those found in shipyards, power plants, offshore oil rigs and
in mines. Our process is based on experiences of 1,000+ welders
used on the oil rigs in the North Sea. Arcon guarantees all models
against corrosion-related failures for five-years.
|
- Smart
surge control reduces weld puddle agitation caused by big drops
from low hydrogen electrodes, eliminating a major cause of slag
inclusions in the weld.
|
- Inverter
circuitry allows for low weight (80lbs/36Kg) and rugged design.
|
|
- Outputs
and Inputs have 1500 Volt RMS isolation and provide 1% maximum
non-linearity
|
- Superior
Capacitive Discharge TIG arc starter ignition without annoying
high- frequency radio interference
|
- Isolated
Output Current that is independently measured by a Hall Sensor
|
- Internal
Gas Valve for automatic gas control
|
- Current/Time
controlled cooling fan protects Duty Cycle, reduces the chance
of
electrical arc-overs, and reduces dust accumulation inside
the welder
|
- Bright,
easy to read panel mounted digital display
|
- 240V
single or three phase, 400V, 480V or 575V dedicated primary
Voltage .
|
- Fiberglass
enclosure allows for rough handling in demanding, tough environments.
|
- The
case has extra thick “skids” on the bottom case
as part of the design allowing for the welder to be easily
dragged on almost any surface.
|
- Foldable
handles with built-in grooves, as well as ridges in the case,
makes nesting of units easy and practical.

MECHANICAL DESIGN
The Workhorse 300ST provides exceptional ruggedness and durability in
tough and demanding environments such as construction, shipbuilding, nuclear
power plants, and offshore welding. The case is made out of solid fiberglass,
which provides sturdier resistance to dents and forces than a sheet metal
case.
ELECTRICAL DESIGN
The Workhorse 300ST uses an SCR inverter design for its power supply.
The inverter design allows for an industrial welding machine weighing
only 79lbs/36kgs. We have chosen the proven SCR component instead of the
IGBT because of reliability. We have strong indications from the market
that SCRs are up to 100 times more reliable in welding applications.
TIG Welding
The Arc Start feature allows no contact between material and torch. The
Arc Start feature is therefore the best solution for critical TIG welding.
Smart Hot Start
Brings the puddle temperature up quickly for good initial penetration.
The amount of Hot Start is dependent on the weld puddle temperature. The
Workhorse 300ST measures the time in between welds. The longer the period
between stopping and starting, the greater the Hot Start current. If the
arc is broken for less than a second, the Hot Start is eliminated. This
prevents the puddle from overheating and burning through.
Thermostat-controlled Cooling Fan
The cooling fan starts automatically when welding current exceeds 100
A. If the current drops below 100 A, the fan will stop after approximately
6 minutes. If the fan is operating when the work is discontinued, the
fan will continue to run and stop after approximately six minutes.
Option – The Warhorse
The Warhorse 300ST is a 400V or 480V welder designed to protect the machine
from voltage spikes and over voltage surges commonly found in environments
with very “dirty” power distribution system, such as power plants
and shipyards and some generators.This high resistance to surges and spikes
has been achieved by vastly increasing the capacity of existing surge
protection circuits, adding new surge protectors and by using high voltage
rated components in critical parts of the inverter circuits.
Safety, Warranty and Service
The welding units are designed to meet UL551 and CE requirements.
The units come with a factory warranty and user manual.
Service will be taken care of by the factory or can in many cases be performed
locally by your service authorized Distributor.
