TheCampbell Hausfeld Arcitech™ arcwelder uses inverter technology toeliminate the mass and weight oftraditional transformer welders, givingyou amazing power in a tiny portablepackage. This constant-current powersource delivers smooth DC power forhigh quality welds with the SMAW(shielded metal arc welding) processusing stick electrodes. It can also beconverted to a TIG (tungsten inert gas)welder with the optional TIG torch(WT6100) and a bottle of inert gaswith a regulator.The Campbell Hausfeld Arcitech™welder runs on 115 Volt – 20 Ampsingle phase input power. It isequipped with infinite amperagecontrol to accurately select the propercurrent needed for various weldingconditions. Internal components arethermostatically protected.UnpackingWhen unpacking, inspect carefully forany damage that may have occurredduring transit. Make sure any loosefittings and screws, etc. are tightenedbefore putting unit into service.Circuit RequirementsThis equipmentrequires adedicated 115 volt circuit. Refer to thefollowing chart for the correct circuitbreaker or fuse rating. Do not runother appliances, lights, or tools onthis circuit while operating thisequipment.. See chart for properextension cord use. Blown fuses andtripped circuit breakers can result fromfailure to comply with thisrecommendation.! CAUTIONSpecificationsThe electrodeholder is "live"(has current potential) when machine isturned on.Components (See Figure 1)1. Work Clamp with 10’ lead and dinseplug connector! WARNING2. Electrode Holder with 15’ lead anddinse plug connector3. Power Cord – 7.5’ – 14AWGX3C-SJTControls – Front Panel (See Figure 2)1. Infinite amperage control knob –controls 5-110 Amps DC output2. Positive Dinse plug connector:a) Connect electrode holder for“reverse” (DCEP) polarity.b) Connect work clamp for “straight”(DCEN) polarity.3. Negative Dinse plug connector:a) Connect work clamp for “reverse”(DCEP) polarity.b) Connect electrode holder for“straight” (DCEN) polarity.4. Yellow LED – Normally off. When lit itmeans that welding current is shut offdue to:a) Thermal overload – duty cycle isexceeded – allow to cool for 15minutes.b) Input voltage outside of safeFor parts, manuals, product & service informationvisit www.chpower.comor call 800-746-5641© 2003 Campbell HausfeldExtension Cords – Length at Rated OutputWeld Output Amps 55 65 90Cord Gauge Cord Length – Feet14 Gauge Cord 65 50 2512 Gauge Cord 100 75 5010 Gauge Cord 150 125 100Figure 1 - Welder Components and ControlsInput Current at Rated OutputInput Amps AC 16 19 24Output Amps DC 55 65 90Weld Volts DC 22 23 24Duty Cycle 100% 60% 35%Power SpecificationsSingle Phase 50/60 Hz 115 Volts132™
