Page 8: Safety
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. -
Page 9: Electric Shock
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. -
Page 10: Fumes And Oxygen Depletion
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. -

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. -
Page 16: Arc Force
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. -
Page 17: Remote Control Connector
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. -
Page 18: Welding Operation
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. -
