This manual contains information such as the specific assembly information, welder duty cycle, welder open circuit voltage, heat control adjustments, recommended electrodes, etc. that are related to this welder only. Table 1 lists the welder specifications. General welder information such as safety information, general installation or assembly instructions, preparation for welding, general operation instructions and welding techniques, etc are in the WELDER'S INSTRUCTION MANUAL, ARC WELDERS. DO NOT ATTEMPT TO OPERATE THIS WELDER until you have read and understand both manuals. Make certain you have removed all documentation from the shipping carton. Additional information on your welder is available through the place of purchase or from the manufacturer. Read SAFETY SUMMARY in the WELDER'S INSTRUCTION MANUAL, ARC WELDERS before unpacking the welder and before proceeding with any procedures or making any attempts to do any welding. Table 1.

Duty cycle is expressed as a percentage of 10 minutes and represents the maximum welding time allowed. The balance of the 10 minute cycle is required for cooling. Your new welder has a duty cycle rating of 20% at maximum rated output at either output tap. SELECTING WELDING The proper determined done. OR DC type of welding current is by the work that needs to be ALTERNATING WELDING • AC CURRENT Alternating current (ac) welding is performed when the welding cables are connected to the AC OUTPUT jacks. This kind of welding ideal for Heavy welding. Plate current is Most ac welding operations will be performed using the LOW AMPERAGE jack. This output tap, because it has a higher open circuit voltage (OCV), provides a deep penetrating arc for welding rusty or thicker metals. American Welding Society (AWS) rated rods 6011 and 7018 type are formulated to work well with the higher OCV of the LOW AMPERAGE jack. The HIGH AMPERAGE jack is better suited for welding thinner pieces because the OCV at this tap is much lower. This tap delivers a shallow penetrating arc and smooth, non-stick welding, preferred for welding thinner metals. AWS rated 6013 and 7014 type rods work well at this tap, since they do not require a very high open circuit voltage to start. a. LOW/180 71.60CV amp. jack = Approx. b. HIGH/230 44.70CV amp. jack = Approx. DIRECT CURRENT WELDING (flat position) This welder has three plug in AC OUTPUTS and two DC OUTPUTS, on the front of the welder. The ac jacks are marked HIGH AMPERAGE, LOW AMPERAGE, and GROUND. The dc jacks are marked, POS and NEG. Connect the electrode output cable to the HIGH AMPERAGE jack for high current (230 amp maximum), low voltage ac operation or to the LOW AMPERAGE jack for low current (180 amp maximum), high voltage ac operation. Direct current (dc) welding is performed when the welding cables are connected to the DC OUTPUT receptacles. The welder has two dc welding options, straight polarity and reverse polarity welding. StraightPolarity Straight polarity dc current flows from the welding rod (negative) into the work piece (positive). Straight polarity dc welding is ideal for: Cutting • Hardfacing • Single • and Build up work for heavy Steel, work, deposits. Polarity Reverse polarity dc current flows from the work piece (negative) to the electrode (positive). Reverse polarity dc welding is ideal for: Overhead Vertical Cast Heavy welding. iron Welding, Welding. Rivet Welding, Sheet Metal Welding, Low Hydrogen and Arc Bronze This welder has a unique OUTPUT AMPERAGE SELECTION (current) control lever for faster, more efficient heat adjustments than plug in style, clicker switch, and crank type designs commonly used in other welders. The OUTPUT AMPERAGE SELECTION control provides amperage control (current adjustment) for both, ac and dc welding operations. To reduce the amperage: the OUTPUT AMPERAGE Squeeze SELECTION control lever (on the front of the welder), push in lightly, and push the lever downward. Welding, Aluminum is done in the dc reverse mode of operation. SETTING THE AMPERAGE CONTROL Brazing, To weld with straight polarity dc, place the electrode cable in the plug marked NEG (negative) and the ground cable in the plug marked POS (positive.). Reverse As you can see, most of the dc current welding polarity • Carbon To weld with reverse polarity dc, place the electrode cable in the plug marked POS (positive) and the ground cable in the plug marked NEG (negative). Rod Welding, Rod Welding. To raise OUTPUT the amperage: AMPERAGE Squeeze SELECTION the control lever (on the front of the welder), pull out lightly, and move the lever upward.
