INTRODUCTION
True to its name, The Workhorse MIGweld 300MS is a very rugged
multi-process MIG/Stick welding machine, weighing approximately
80lbs/36.3Kgs, and designed specifically for the industrial market.
The underlying design concept was to employ proven electrical
and mechanical technologies and build a “no-nonsense”,
cost-effective machine where usability, reliability and ruggedness
are the most important design parameters.
The electric circuitry is based on principles that over the years
have proven their functionality and reliability in the over 100,000
welding machines sold and used around the world.
The fiberglass reinforced plastic case also provides unique benefits
over the sheet metal and thermoplastic cases used in most competing
products.
FEATURES |
- MIG/Stick
welding current from 30 - 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.
|
|
|
- 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 MIGweld
300MS can be used for MIG short arc with puddle control and
spray transfer, Stick and carbon arc gouging.
|
- The MIGweld
300MS uses all types of electrodes, including 6010-5P
|
- The MIGweld
300MS is equipped with arc force control for stick welding
|
- 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.
|
- 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.
|
- Inverter
circuitry allows for low weight (80lbs/36.3Kg) and rugged
design.
|
- Fiberglass
enclosure allows for rough handling in demanding environments
like construction sites, shipyards and offshore oil rigs.
|
- 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.
|
- Units
can be connected in parallel for higher current or in series
for higher voltage, should there be a need for that.

MECHANICAL
DESIGN
The Workhorse provides exceptional ruggedness and durability
in demanding environments such as construction, shipbuilding
and offshore welding. The case is made out of fiberglass, which
provides sturdier resistance to dents and forces than a sheet
metal case.
ELECTRICAL
DESIGN
The Workhorse uses an SCR inverter design for its power supply.
The inverter design allows for an industrial welding machine
weighing only 80lbs/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.
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 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.
Arc Force
This allows the operator to adjust the current surge which results
when a drop shorts the arc.
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 300MS 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 coal mines, power plants, steel mills 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.
All 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.
