Workhorse 300SMT


The Workhorse 300SMT is a Presettable, Multi-Process, CC/CV Inverter Welder

20-400 amps / 10-35 VDC

Rugged & Reliable
Designed specifically for the industrial market. 

The ideal welder for the harsh conditions found in:
Shipyards  / Offshore Facilities / Mines / Construction
Oil & Gas Production / Paper Mills /  Rental Fleets 

Lightweight & Compact
Just 90-lbs (41-Kgs) / Measuring:19"L x 11"W x 18"H.

 

The Latest Addition to the Proven Arcon Workhorse Line, is the Model 300SMT Inverter  

  • A "Pre-Settable" Multi-process, CC / CV Inverter Welder, for:
    Stick / TIG / MIG & Flux-core welding, in all conditions.
  • 20-400 Amps gives you all the power you need in an 80 lbs unit!
  • Available in single voltage models for: 240V, 480V, 575V or 400V. Also available in our Flexi-volt model, which operates between: 240V & 480V  with our "auto-sensing" circuit.(single or three phase).
  • All models carry Arcon's 5-year parts & labor warranty, plus ...
  • Our, Exclusive Lifetime warranty against Corrosion-related failures
  • Arc gouging up to 3/8" (10mm) in Stick mode
  • Solid fiberglass case for rugged environment

  • Constant Current (CC) welding with output current from 20 – 400 Amps, in 2 ranges, for; Stick & Lift Start TIG
  • Constant Voltage (CV) welding with output voltage from 10 to 35 VDC, in 2 ranges, for: MIG & Flux-core
  • Large digital meter clearly shows pre-set current or voltage as well as the actual during the welding process.
  • Hot Start; This feature temporarily increases of the output current during the start of a weld, this helps ignite the arc and start the puddle quickly.
    Hot Start provides improved arc ignition without the electrode sticking and helps avoid contamination of the weld.
  • Industry standard, 14-pin control connection, allows welder to be paired with a wide variety of accessories.
  • Available with either Dinse or Tweco output connectors. (specify when ordering)
  •  Available in single voltage models; 240V, 480V, 575V and 400V
  • Also available in Arcon's "Flexi-volt" model which operates between 240V & 480V, single or 3-phase, using an auto sensing circuit. 
  • Carbon arc gauging protection. (Circuit design that eliminates the harmful currents caused during arc gouging has been added)
  • Multiple zones of thermal protection will shut off the welder before damage occurs in the event of thermal overload.
  • Built-in circuit breaker protects the welder against electrical overload.
  • Reliable, easy and inexpensive to repair; SCR construction.
  • Corrosion Resistance: All Arcon welders include our 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 thousands of welders used on the oil rigs in the North Sea. Arcon guarantees all models against corrosion-related failures for five-years.
  • Heavy duty fiberglass composite enclosure allows for the 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 protecting the welder when dragged on almost any surface..
  • Fold-able handles and 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

OPTION: The Warhorse

The Warhorse is an option to The Workhorse 300SMT.
It is available in standard voltages and is 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.

 

 

The new Workhorse 300SMT power source combines time-proven technology with modern components to provide high-quality performance, in any environment.  
The digitally controlled SCR type inverter is very reliable in all welding applications and able to deliver up to 400 Amps@29% Duty Cycle.

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 a fiberglass composite material, which provides sturdier resistance to dents and forces than a sheet metal case.

ELECTRICAL DESIGN

All Workhorse models use 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 to increase reliability. Indications from the market show that SCRs are much more reliable in welding applications than the IGBT's, used by most other manufacturers.

All of our electronics are coated multiple times to protect against corrosion and arc-over.


Safety, Warranty and Service

The welding units are designed to meet UL551 and CE requirements.

Duration of Warranty Period
The standard Arcon warranty covers equipment failure for a period of THREE (3) YEARS and a 5-year guarantee against corrosion-related failures in natural environments.
This coverage is only extended to the original purchaser.
The warranty period begins on the date of delivery. 
Proof of purchase documentation is required for any and all warranty claims to establish the warranty period.

What is Covered in this Warranty
Within the US; All material and labor required to repair or replace the defective product, for any failure that occurs with the applicable duration of the warranty period, that is the result of defects in materials or workmanship for products purchased and used in the 48 mainland states, Alaska, Hawaii and Washington, D.C.
The manufacturer also warrants that the product conforms to its specifications as stated in product literature supplied by Arcon Welding.

Outside the US; The warranty covers defective parts for THREE (3) YEARS, with a 5-year guarantee against corrosion-related failures in natural environments.
This warranty is only is extended to the original purchaser.  
The warranty period begins on the date of delivery.
Proof of purchase documentation is required for any and all warranty claims to establish the warranty period.

Service may be obtained directly from the factory or, in many cases, may be performed locally by an authorized Distributor.
