DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT WITHOUT READING THIS MANUAL AND THE SAFETY PRECAUTIONS CONTAINED THROUGHOUT. And, most importantly, think before you act and be careful.
i i SAFETY WARNING CALIFORNIA PROPOSITION 65 WARNINGS Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. The Above For Diesel Engines The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. The Above For Gasoline Engines ARC WELDING CAN BE HAZARDOUS.
ii ii SAFETY ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. 3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.
iii iii SAFETY WELDING and CUTTING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available. 6.b.

Protegez-vous contre la secousse électrique: a. Les circuits à l’électrode et à la piéce sont sous tension quand la machine à souder est en marche.
v v SAFETY Electromagnetic Compatibility (EMC) Conformance Products displaying the CE mark are in conformity with European Community Council Directive of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility (89/336/EEC). It was manufactured in conformity with a national standard that implements a harmonized standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment.
vi vi SAFETY Electromagnetic Compatibility (EMC) The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may extend beyond the boundaries of the premises. Methods of Reducing Emissions Mains Supply Welding equipment should be connected to the mains supply according to the manufacturer’s recommendations.

A-2 A-2 INSTALLATION Read entire installation section before starting installation. SAFETY PRECAUTIONS WARNING ELECTRIC SHOCK can kill. • Only qualified personnel should perform this installation. • Disconnect input power by removing plug from receptacle before working inside INVERTER ARC™ 230. Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment. • Insulate yourself from the work and ground. • Always wear dry insulating gloves.
A-3 A-3 INSTALLATION 230V INPUT FIGURE A.1 The INVERTER ARC™ 230 is provided with a 230V cable, 6.0ft.(1.8m) in length, with a 50 Amp (NEMA 650P) plug molded onto the cord. The rated output of the INVERTER ARC™ 230 is available when connected to a 30A branch circuit. When connected to a branch circuit with lower ampacity, lower welding current and duty cycle must be used. Other loads on the circuit and fuse/circuit breaker characteristics will affect the available output.
B-1 B-1 OPERATION Read and understand this entire section before operating your machine. WELDING CAPABILITY The INVERTER ARC™ 230 is rated at 150 amps at 30% duty cycle on a ten minute basis. It is capable of higher duty cycles at lower output currents. If the duty cycle is exceeded, a thermal protector will shut off the output until the machine cools. SAFETY INSTRUCTIONS WARNING ELECTRIC SHOCK can kill. • Do not touch electrically live parts such as output terminals or internal wiring.
B-2 B-2 OPERATION CONTROLS AND OPERATIONAL FEATURES FRONT CONTROL PANEL (See Figure B.1) 1. Output Current Knob: A Potentiometer used to set the output current used during welding. Set the output according to the type and size of electrode. 4. Thermal LED: This indicator will turn on when the machine is overheated and the output has been disabled. This normally occurs when the duty cycle of the machine has been exceeded. Leave the machine on to allow the internal components to cool.
B-3 OPERATION STICK-WELDING CIRCUIT B-3 This figure closely resembles what is actually seen during welding. The “arc stream’’ is seen in the middle of the figure. This is the electric arc created by the electric current flowing through the space between the end of the electrode and the work. (See Figure B.3) FIGURE B.3 The temperature of this arc is about 6000°F (3315°C), which is more than enough to melt metal.
B-4 B-4 OPERATION 4. Immediately after striking the arc try to maintain a distance from the workpiece that is equivalent to the diameter of the electrode used. Maintain this distance as constantly as possible during the weld. Whenever possible, weld from left to right (if righthanded). Hold the electrode at a slight angle as shown. (See Figure B.5) FIGURE B.5 5. As the electrode burns off the electrode must be fed to the work to maintain correct arc length.
B-5 OPERATION Making a TIG Weld: 1. Connect the work cable to the positive “+” output terminal. 2. Connect the TIG torch to the negative “-“ output terminal. 3. Connect the gas line from the TIG torch adapter to the gas regulator connected to the gas bottle. 4. Open the gas valve on the gas bottle and adjust the gas regulator to approximately 20-30 cfm. 5. Set the amperage based on material thickness: Steel Thickness (1/16”) 1.6mm (1/8”) 3.2mm (3/16) 4.
C-1 ACCESSORIES C-1 CABLE PLUGS OPTIONAL ACCESSORIES AND COMPATIBLE EQUIPMENT K852-25 - Cable Plug Kit attaches to welding cable to provide quick disconnect from machine. Factory Installed TIG Torch Parts Kits - Parts kits are available for the PTA-9FV and PTA-17 TIG torch. These kits include back cap, collets, collet bodies, nozzles and tungstens.
D-1 D-1 MAINTENANCE SAFETY PRECAUTIONS WARNING WARNING ELECTRIC SHOCK can kill. • Have an electrician install and service this equipment. • Turn the input power off at the fuse box, disconnect supply lines and allow machine to sit for five minutes minimum to allow the power capacitors to discharge before working inside this equipment. • Do not touch electrically hot parts. Do not open this machine and do not introduce anything into its openings.
