#13 Use the shade chart below to select proper shade control setting based on your welding process. We recommend starting at shades 12 or 13 and adjust lighter based on the welding application and personal preference. Application Welding Arc Current in Amperes Protective Shade No. Stick Electrodes Less than 40 40.80 80.175 175.300 #9 #10 #11 #12 . #13 MIG Less than 100 100.175 175.300 #10 #11 #12 . #13 Gas Tungsten Arc Welding (TIG) Less than 50 50.100 100.200 200.300 #10 #11 #12 #13 Page 5 Sensitivity Control (XTV And XTP Models Only) The sensitivity control is used to make the lens more responsive to differing light levels experienced in various welding processes. We recommend a (Mid-Range or 30.50%) sensitivity setting for most applications. Please refer to the chart below for recommended settings. Sensitivity Control (XTV And XTP Models Only) The sensitivity control is used to make the lens more responsive to differing light levels experienced in various welding processes. We recommend a (Mid-Range or 30.50%) sensitivity setting for most applications. Please refer to the chart below for recommended settings. Recommended Sensitivity Settings Stick Electrode Mid-Range Short Circuiting (MIG) Low/Mid-Range Gas Tungsten Arc (TIG) Mid/High-Range Plasma Arc Cutting/Welding Low/Mid-Range Helpful Hint For Setting Sensitivity In Low Amperage Tig, 50 Amps And Below: 1. Face the helmet front toward the floor. 2. Turn the sensitivity setting toward HI until the lens darkens. 3. Now, reduce the sensitivity by turning the control to the left until the lens lightens; you are then ready to weld. 4. When job is completed, return sensitivity control to mid-range. Lens Delay Control The lens delay control is used to slow the lens-switching time to the clear state after welding. The delay is particularly useful in eliminating bright after-rays present in higher amperage applications where the molten puddle remains bright momentarily after welding. Low Battery Indicator The low battery indicator lights when 2.3 days of battery life remain (see battery recommendations below). Model XTF: Non-replaceable Lithium battery. Model XTV: Replace with 2 AAA Alkaline batteries. Model XTP: Replace with Lithium battery CR2450. Page 6 Adjustment of the Headgear for Maximum Comfort There are four adjustments on Hobart headgear that can be adjusted for maximum comfort: 1. Headgear Top – Adjusts headgear for proper depth on the head to ensure correct balance and stability. 2. Headgear tightness – To adjust, turn knob located on the back of the headgear left or right to desired tightness. 3. Stop angle adjustment – Five pins on the right side of the headband top provide adjustment for the forward tilt of the helmet. To adjust, loosen the right outside tension adjustment knob and lift on the control arm tab to move it to the desired position. Retighten tension adjustment knob. 4. Distance adjustment – Adjusts the distance between the face and the lens. To adjust, loosen both outside tension knobs and slide forward or back to desired position and retighten. (Both sides must be equally positioned for proper vision.) Replacement of the Front and Inside Lens Covers Warning! Never use the auto-darkening lens without the inside and outside lens covers properly installed. Welding spatter will damage the auto-darkening lens voiding the warranty. 1. Outside . Place helmet on a flat surface. Grasp the front lens holder with one hand while pushing the inside retaining clips of the lens holder outward. Do one side at a time, gently pulling the front lens holder away from the helmet as each tab is released from its retaining clip. Once released, the outside cover lens can be replaced. 2. Inside . Remove the inside lens cover by following the procedure in Step Adjustment of the Headgear for Maximum Comfort There are four adjustments on Hobart headgear that can be adjusted for maximum comfort: 1.
