You have made the right decision to invest in your health. But would it surprise you to learn that you may be blowing it all away. Literally. This indicates, if properly worn, the level to which the respirator protects the wearer from the surrounding pollutants. The 3 M Adflo Powered Air Purifying Respirator (PAPR) when worn with any of the 3M Speedglas Respiratory Welding Helmets has a RMPF of 50, meaning that they supply air which is a minimum of 50 times cleaner than the air the welder would otherwise be breathing unprotected. Do not attempt to remove contamination using for example compressed air as this will destroy the filters, the equipment will not give the expected protection and the warranty will be invalidated. They are not built to deal with high pressure compressed air. When you use compressed air to blow out your PAPR filters, the force of the air can create holes in the filter. These holes can be extremely small meaning that they may not be visible to the naked eye.http://www.tourofoman.om/gctcms/fckeditor/userfiles/3m-oac100-manual.xml

As a result, your filter may appear to be in working order, however, particles may be able to fit through the holes and reach your airways. This would mean that the integrity of the filter has been compromised and you are not receiving the desired level of respiratory protection. Damage caused by large particulates entering the motor as a result of cleaning your filters voids the Adflo motor warranty and can be costly to replace! If you notice any damage, particle breakthrough, or the filter becomes loaded (indicated by the particle loading indicator turning red), change your Adflo particle filter and pre-filter immediately to ensure you are receiving the desired level of protection.Start using an Activated Carbon Filter How has the welding industry grown in recent years.

Alaina Couch 5.0 out of 5 stars It is definitely worth the money. I am a production welder, so I spend about 8-12 hours a day under my hood. I TIG weld stainless steel, aluminum, and cold roll steel. I also MIG weld aluminum and steel. This hood, not only keeps me in fresh air, but also cool air.http://aiyta.com/images/3m-accuglide-2 -manual.pdf Two days with this thing on and I feel better, and less congested. I like the multipurpose function of this hood. Going from welding to grinding and back to welding without taking off my hood is awesome. Not breathing metal dust is awesome. I should have bought this thing two years ago. Michael M. Certified WelderWelding is a new experience not having to breath fume all day!I feel so much better, plus no fogging, fresh air blowing in the hood. The chin strap had a nice comfortable cloth cover. It is almost a closed system. Having the grind shield is awesome, I don't have to stop what I am doing to put a grind shield on. Price is steep, but you can't put a price on good health.

The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.Note: The Tape Application Monitor can be used to signal a low tape condition by turning on the panel indicator and (optional) beacon light. The system can be set to stop the case sealer when either the upper or lower low tape supply sensors detect a low tape condition. (Refer the Theory of Operation and Adjustments sections of this manual for further information on this feature.) Figure 2-23 The sensor should be positioned to allow the operator ample time to replace the tape roll before adversely affecting your production process when the system is set to indicate a low tape condition. Setting the PLC Application Parameters The PLC controller is equipped with a display used for changing and monitoring data. There are three modes of operation which include Device, Digital Trimmer and System Mode. The Device modes are used for changing timers and registers for the your specific application. The PLC also has a Locking feature that is factory set to “Loc” to prevent inadvertent changes to the initial program parameters. To adjust the sensor: 1) Check the distance between the sensor and target. The gap must be less than 0.079 inches (2 mm) and must not touch the target or interfere with the motion of the dancer arm. Note:: For application specific data register and timer values refer to the Theory of Operation section of this manual. For general information on setting the data memory registers and timers refer to “Access Window” section of the Keyence Visual KV Series Installation Manual. 2) If necessary, loosen the M8 sensor jam nuts and reposition the sensor. 3) Rotate and hold the dancer arm in a position that represents your low tape condition. This can be accomplished by placing a spacer or a tape roll with the amount of tape that represents the low tape condition. Slots are supplied to allow adjustment. If the operational configuration is not displayed on the PLC while in the Device mode refer to the trouble shooting section of this manual. Figure 2-26 17 Installation and Set-Up (Continued) Changing operational configuration: or key In the Device mode press either the until the number 75 is displayed in the upper right hand corner. (data memory register 75). Note: The screen will display “User 50” after changing the taping head configuration (value of register DM0075) to indicate a new configuration has been selected. The Indicator light on the control box and the beacon light (optional) will flash. The system must be reset for the changes to take effect. They are set at the factory for standard sensor installation.Refer to the adjustment section for more information.For a more complete description refer to Operation and adjustment Sections of this manual.The PLC controller contains programs to interpret the information received from these sensors. This system has a setup menu for selecting the system configuration and operating parameters for the application. Operational Explanation The operation is based on information received from the sensors supplied with this system. They sense the presence of electrical current supplied to the case sealer, the presence of a box as it passes through the machine, the dispensing of tape from the supply roll and a low level of tape on the supply roll. The spring loaded dancer arm assembly is mounted adjacent to each taping head to be monitored. The dancer arm roller is placed in contact with the tape supply roll to monitor tape movement and supply level. Seven targets spaced equally around the circumference of the dancer arm roller, pass the tape dispensing sensor to indicate when tape is dispensed. The information obtained from the tape dispensing sensor is used to calculate the tape apply V1 (i.e. supply roll tape velocity while taped is being applied) and tape cut V2 (i.e. supply roll tape velocity after tape has been cut). The calculations occur at two different points with information obtained from the box presence sensor. The first calculation for V1 begins when the leading edge of the box reaches the tape cutoff bracket and ends when the trailing edge reaches the cutoff bracket. The calculation for V2 begins at a point after the trailing edge has passed the cutoff bracket and ends after the time expires ont TH053. A tape apply velocity less than or tape cut velocity greater than these preset values will generate a fault code and stop the case sealer. This system consists of a current sensor, a box presence sensor and 2 dancer arm assemblies for monitoring tape activity of both an upper and lower taping head. Each sensor is independently adjustable for your specific application. The dancer arm assemblies are spring loaded mechanisms designed to remain in contact with the tape supply rolls on your case sealer. A second sensor at the opposite end of the arm senses the angular position of the dancer arm. As the supply roll gets smaller the arm moves closer to the sensor and the point you have selected to replace the roll. The current sensor is located in the main control box It is placed in-line with the case sealer’s power cord wiring and is used to detect current flow and determine whether or not the case sealer is running. This sensor allows the system to reset automatically after a fault condition is corrected by simply restarting the case sealer. Note: The following explanation is for both upper and lower taping head monitoring. It includes additional detail on program timers used to delay the start of the velocity calculations for the upper head due to the physical offset of the upper and lower taping heads (upper taping head is approximately 5 ?” behind the lower taping head position). The box present sensor assembly consists of a reflector and a sensor mounted on opposite sides of the case sealer. The sensor and reflector 19 Theory of Operation (Continued) Upper and Lower Tape Head Monitoring (Detailed description) The typical installation and taping head orientation is shown in Figure 3-1. The box enters the case sealer from right to left in the illustrations. The leading edge of the box is detected by the box present sensor (Figure 3-2) starting timer TH051. Timer TH051 is adjustable and represents the time required for the box to travel from the sensor to the taping head cutoff bracket. The pulses are accumulated from the lower tape dispense sensor as the tape supply roll rotates. These pulses are counted until the trailing edge of the box passes the taping head cutoff bracket (Figure 3-3). The tape, at this point, has not been cut and the tape apply velocity (V1) is calculated. The first filter is a general calculation that compares the calculated velocity (V1) to a preset V1min. If (V1) is less than or equal to (V1min) the system will generate a NO APPLY fault and stop the case sealer. Figure 3-2 Note: (V1min) is set at half the expected belt speed. The second filter is used to ensure tape was dispensed continuously as the box passed through the case sealer. The Elapsed Time and pulse count are divided into smaller segments. If at least one pulse was measured during the last segment of the apply cycle (i.e. just before the tape is cut) then tape was successfully applied to the box. If the pulse(s) measured during the last segment of time equals zero a NO APPLY fault is generated. The last filter used is to determine if the tape was successfully cut. As the trailing edge of the box passes the taping head cutoff bracket (Figure 3-3) timer TH052 starts. This timer is similar to TH051 and represents the amount of dwell time after the apply cycle has completed and the cut cycle begins. The fault will also be indicated by the control panel indicator light and the beacon light (Optional).
