The Workhorse Model-300MS: MIG/Stick Welder, 30-400Amps

By definition, a "WORKHORSE" is : "A markedly useful or durable machine"...... Webster Dictionary

True to its name, the portable Workhorse MIGweld 300MS is an extremely rugged, multi-process MIG/Stick welding machine, weighing approximately 80lbs/36.3Kgs, and designed specifically for the industrial market. The design of this machine employs proven electrical and mechanical technologies which results in a “no-nonsense”, cost-effective welder where usability, reliability and ruggedness are the most important design parameters.

The electric circuitry, which utilizes SCR's, 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 composite case also provides unique benefits over the sheet metal and thermoplastic cases used in most competing products.

The Workhorse 300MS
MIG/Stick Welder, 30-400A

For the following processes:
MIG (GMAW)
Flux Cored MIG (FCAW)
Stick (SMAW / MMAW)
Air Carbon Arc Gouging (CAC-A) Stick (SMAW or MMAW)
Scratch-start TIG (GTAW)

  • A multi-process MIG / Stick welder.
  • Provides a Command Arc function in MIG which minimizes spatter
  • Available in single voltage models for: 240V, 480V, or 400V. Also available in our Flexi-volt model, which operates between: 240V & 480V  with our "auto-sensing" circuit.(single or three phase).
  • Exclusive 5-year guarantee against Corrosion-related failures
  • 10-400 Amps gives you all the power you need in an 80 lbs unit! 
  • Command Arc for spatter free MIG welding
  • Constant power for Stick welding gives you great control with forgiving arc
  • Arc gouging up to 3/8" (10mm)
  • Solid fiberglass case for rugged environment
  • Corrosion Protection in all machines with 5-year guarantee

 

  • MIG/Stick welding current from 30 - 400 Amperes in 2 ranges.
  • Available in Arcon's "Flexi-volt" model which operates between 240V & 480V, single or 3-phase, using an auto sensing circuit.
    Also available in single voltage models; 240V, 480V, 575V and 400V
  • Easy to strike the arc
  • 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 Arcon welders 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.
  • Fold-able 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 79lbs/36kgs. We have chosen the proven SCR component instead of the IGBT to increase reliability. Indications from the market show that SCRs are up to 100 times more reliable in welding applications.

TIG Welding

The Lift Start feature allows contact between material and electrode, with no damage to the electrode, and is a low-cost solution for TIG welding since no expensive high frequency or capacitor discharge circuits are needed.

Smart Hot Start

This feature brings the puddle temperature up quickly for good initial penetration. The amount of Hot Start required 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 the weld burning through.

Arc Force

This allows the operator to adjust the current surge which results when a drop shorts the arc.

Remote Hand Control

Hand operated remote control with 25 feet of cable.

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.

 

The Workhorse MIGweld 300MS is a very rugged 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.
