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.

A-2 INSTALLATION SAFETY PRECAUTIONS A-2 Connecting a water-cooled torch: WARNING 1. Disconnect all power to the power source. ELECTRIC SHOCK can kill. • Disconnect input power by removing plug from V310-T/V311-T before working inside Cooler. • Do not touch electrically “hot” parts inside Cooler. • Have qualified personnel do the installation, maintenance and troubleshooting work. ---------------------------------------------------------------------- 2.
B-1 B-1 OPERATION FRONT PANEL PRODUCT DESCRIPTION (See Figure B.1) The new COOL ARC® 35 is an intelligent cooling unit equipped with a variable speed three phase rotary pump and an embedded microprocessor PC board which controls the pump operation, fan operation, and the overall functioning of the unit. The cooler operation is enabled by the power source and utilizes a “cool as needed” approach, so the pump and fan speed vary based on real coolant temperature.
B-2 B-2 OPERATION USER INTERFACE DISPLAY The 7 segment display shows the coolant temperature during normal operation, but also displays additional cooler status information. Status indications: Display Meaning oo OFF mode. The cooler has been turned off by the user. -- AA Stand-by mode. The cooler has power and is ready to function, but the selected weld mode is not a water cooled operation (STICK modes), or the unit is initiating at power up. Alarm mode.
B-3 OPERATION USER INTERFACE PUSH BUTTON The push button on the user interface of the cooler has two different functions: Holding the push button in for 3 seconds toggles the cooler ON and OFF. When the cooler is turned OFF, the display will shown “oo”. In this condition, the cooler can only be turned ON again by pressing the push button for 3 seconds again, or by cycling input power to the power source. The power source has no control over the cooler when it is OFF.
D-1 MAINTENANCE SAFETY PRECAUTIONS D-1 RESERVOIR COOLANT LEVEL WARNING ELECTRIC SHOCK can kill. • Disconnect input power by removing plug from V310-T/V311-T before working inside Cooler. • Do not touch electrically “hot” parts inside Cooler. • Have qualified personnel do the installation, maintenance and troubleshooting work.
D-2 MAINTENANCE D-2 INSPECT CONDITION OF COOLANT Prepare the disinfectant: Make a quantity of only what is needed to avoid an excess Bulk preparation (for coolers serviced in quantity): 5.7L (1.5 gals.) of pure, fresh water per cooler and 1.0ml of additive per cooler. Example: for 100 coolers, add 100 ml to 150 gals. of pure fresh water, Pour 5.0L (1.3 gals.) of disinfectant into the empty reservoir. Recap the reservoir.
