ARCON Welding Equipment LLC or its Authorized Repair Center will perform warranty Repairs. The Workhorse 300S or any of its parts must not be altered without the prior written approval of ARCON Welding Equipment LLC. Any malfunction,...
1. SAFETY Safety is eveyone’s responsibility. ARCON designs every machine with safety in mind, and a safe work environment depends largely on you. Do not install, operate, or repair this equipment without carefully reading this manual and observing all of the safety precautions mentioned.
ELECTRIC SHOCK Precautionary measures must be taken to provide maximum protection against electrical shock. Electric shock can injure or Kill WARNING 1. Do not touch live or energized electrical parts or store metallic objects near power. 2. Ground the work or metal to be welded to a good electrical (earth) ground. 3.
FUMES and OXYGEN DEPLETION Only weld in areas or rooms where adequate ventilation of weld gases is possible, and where there are not fire, smoke or explosion hazards. When working in a confined space always have trained support personnel nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death.
PRODUCT DESCRIPTION AND INFORMATION 2.1 INTRODUCTION TO THE WORKHORSE 300S The Stickweld 300S is a portable welder using an inverter-type power supply to generate the output power.
3.1 Handling and Unpacking the Welder Since the Workhorse 300S machine weighs approximately 90 pounds in the shipping carton, no fork lift or special handling equipment is necessary to move the machine. The shipping carton has built-in reinforced handles to enable two people to easily transport the machine.
3.3 Selecting Suitable Supply Cables The standard power input cable for the Workhorse 300S welder is a high quality #10 gauge that is 12.5 feet long. The secondary cables that connect the electrode holder or TIG torch vary in length according to needs, but are normally 1/0 gauge and 25 feet in length.
3.5 F USES It is recommended that input fuse sizes be in accordance with the table below: Input Voltage Welder input Recommended Fuse Maximum Amperage Capacity 240 V Three-Phase 240 V Single-phase 400 V 480 V 575 V Table 3.0 3.6 O UTPUT CONNECTIONS The standard supplied output connector types are female Dinse type (manufactured by...
4. OPERATION WARNING! PLEASE READ CHAPTER REGARDING SAFETY 4.1 General Description The Workhorse power source combines time-proven technology with modern technology to provide high-quality performance. The digitally controlled SCR type inverter is very reliable in welding applications and able to deliver up to 400 Amps@29% Duty Cycle. 4.2 Design Features The Workhorse power source is designed to be portable and easily transported to provide many benefits.
4.3.5 Arc Force Control This control is used to adjust the Arc Force on constant current applications. The control is fully adjustable from 0 to 100%, with 0 being very soft and 100% being very hard. When adjusting the Arc Force, the low settings will produce a soft arc and the high settings will produce a more forceful or driving arc.
4.3.8 Remote Control Connector Two different types of remote control connectors are available. Units come standard with a 14-pin panel mounted female socket plastic shell connector. Some units may be delivered with a 14-pin female socket metal shell connector. The remote control function is automatically activated when a pin compatible remote control is plugged into the connector.
Welding Operation 4.4.1 Stick Welding 1. All secondary outputs must be connected to output terminals of the power source 2. After the primary input connections have been made, close the main wall disconnect switch or circuit breaker. 3. Place the primary power selector in the ON position. This will turn on the control circuitry. The Power-On light on the front panel will be lit.
Please note: Opening up the case voids the Warranty. Maintenance or repair should only be performed by an authorized ARCON Service Center, or by the factory. Do not permit untrained persons to inspect, clean, or repair The Workhorse. Please call the factory for the location of the Authorized ARCON Service center nearest you.
6. ELECTRICAL SPECIFICATIONS & DIAGRAMS 6.1 General Information Circuit breaker The 3 phase elecric input power is connected to the circuit breaker (K). When the welder is used for 240 V single phase, the brown conductor is not connected. If the correct phases are connected the fan will start and run for a few minutes and then stop.
