When your welding job won’t wait and you’re close to other workers, help protect them with the Wilson Orange See-Thru Welding Curtain. The heavy-duty 14-mil vinyl welding screen is designed to filter far and near ultraviolet (UV) radiation and blue light. They come with ready-to-hang grommets (framing and tubing sold separately) and are a smart item on your list of welding supplies.
The heavy-duty orange vinyl is designed to filter far / near UV radiation and blue light
Grommeted and ready to hang (tubing or framing is not included); Plastic grommets are placed 8” apart on one width side and 16” apart on both height sides
These welding screens help protect bystanders from ultraviolet light while welding is being performed; not intended for use in lieu of visors, goggles, eyewear or welding helmets
WILSON Welding Curtains meet or exceed California State Fire Marshall (CFM) requirements for flame resistance
Instructions for using the Operating Cost Analysis Tool
The Operating Cost Analysis Tool is divided into four sections:
- Section 1: Input Data - raw data used in the calculations
- Section 2: Output Data - calculated data based on Operating Cost formulas
- Section 3: Summary Data - a comparison of the initial and energy costs for each option
- Section 4: Graph Data - a graphical comparison of the initial and energy costs for each option
Enter the appropriate data on the "Input Data" page
If necessary, you may change the default data that automatically appears in the input fields.
All of the WHITE cells must contain input data for the model to work. If fields are left blank or as zeros the data will not be complete. Not a number (NaN) and infinity values indicate an error.
The system airflow rate is set at a default equal to 2000cfm multiplied by # of Filters. The system airflow rate appears when you enter a value in the "# of Filters" field. To change this default, simply enter the actual system airflow in this field and do not change the "# of Filters" field.
To clear all fields and reset the inputs to their defaults, use the "Clear All" button. To reset only the input fields, use the "Default Input" button.
The "Calculations" section displays the calculated data based on the input data. These calculations are use to create the Summary Data. It contains the following sections: 1) Initial Investment Costs 2) Energy Costs.
Energy Calculations are based on the following formula:
Filter pressure drop is calculated as the straight line average between the initial pressure drop and the final pressure drop.
The "Calculations" section cannot be changed.
The "Summary Data" section displays a comparison of the results for each option. This page also recommends which option would realize the most savings.
The "Graph Data" displays a graphical comparison of the cost categories between each filter option.
