FUNCTIONS
- Shade adjustment: Auto (shade level adjusts automatically depending on arc intensity) or Manual (user adjust), adjust in increments of +/- 0.5 via external or internal controls
- Shade Deviation: When using Auto shade, +/- deviation (fine adjustment) can be adjusted in 0.1 increments to up +2.0/-2.0
- Welding mode: Variable shade 9-14
- Cut mode: Variable shade 4-8
- Grind mode: Locks lens to light mode (shade 3), activate on/off via external button or internal controls
- Shade Lock: Switches off auto-darkening function & locks lens to a selected shade level (4-13), ideal for oxy cutting & similar processes where conditions may not be ideal for normal auto-darkening function
- Memory: Save up to 9 favorite settings (recalls shade, sensitivity & delay settings), with ‘instant save’ function on external controls
- Delay (switching time from dark back to light after welding stops): Auto or Manual 0.1-1.0s
- Gradient Mode: Gradual return (slope down) from dark to light, mirrors cooling of the weld pool to reduce eye strain
- Sensitivity: Auto or Manual 0-9 settings
- Tack Mode: Returns to shade 5 (instead of shade 3) between welds to reduce fatigue
- Respirator airflow speed adjustment: 170, 200, 230 L/min
