Thus, it is useless when paired with an AC-based welding machine. When it comes to polarity due to its coating this welding rod can only be used with a DC current. A 1/8 inch 6010 welding rod works best with an amperage of between 75 and 125 amps. And the best amperage setting depends on a rod’s diameter. The 6010 welding rod amperageĭifferent stick welding rods are suited to different amperage settings. Also, it leaves a very thin layer of slag which can easily be removed. Another characteristic of this rod is that it cools quickly. Cellulose makes up to 30% of its weight.Īs such, it is sometimes referred to as a cellulosic electrode. It has a coating comprised of cellulose, titanium dioxide, magnesium, aluminum, and metallic deoxidizers. This electrode offers deep penetration thanks largely to its coating. Additionally, it can be used in all four positions, horizontally, vertically, flat and overhead. A Comparison chart of Different welding rod sizesĭifferent rod sizes and their amperages Rod SizesĪrguably the most common welding rod out of the four, the 6010 has a tensile strength of 60,000 pounds per square inch. This number varies from rod to rod and we will go into it in more detail later on.īut for instance, below we are giving you all the welding rod general specifications and their comparison. This number, therefore, influences which currents should be used. The last number represents which coatings have been used on the rod. In most cases, the third number will be ‘1’, meaning the rod can be used in all positions.Įxx1x – Flat, Horizontal, Vertical (up), Overhead.Įxx4x – Flat, Horizontal, Overhead, Vertical (down). The third number tells you the position in which the welding rod can be used. The higher the number the stronger the stick electrode. If for example, your rod has the number ’60’ then it means it can withstand 60,000 pounds per square inch. This refers to how much stress the weld bead can take. The first two numbers represent a rod’s tensile strength. These numbers refer to a different characteristic of the rod. When you buy a welding rod you will notice three sets of numbers imprinted on it.

So if you're going to use welder's glass, expect to do some considerable white balance correction (you do shoot in RAW, right?) - or convert to black & white - and accept whatever optical peculiarities you may get from the particular sample you get. All this, of course, means that it's going to be a rather expensive "pane of glass."Ī welder's glass alternative is going to have a strong color cast (the one I used for a solar eclipse was very green), as well as possible image quality issues such as distortion or ghosting (where off-angle light gets reflected internally within the filter) - especially with wide-angle lenses where the corners of the frame are receiving light at an angle far from perpendicular to the filter plane. It is also of an optical grade of material and design, so as to reduce any aberrations or ghosting caused by having a pane of glass in front of your lens. To clarify the math, the reverse of the top equations is:Īnd since 1 f-stop is half as much transmission:Īn ND filter is specially made to be of neutral-density ("ND"), meaning that it reduces the light level evenly across the visible light spectrum, therefore retaining the original white balance of the light source. It was surprisingly difficult to find this information online! It seems that most welding companies would rather tell you what shade number you need for specific applications rather than the actual formula they used to determine that shade number. Thus, if you wanted, say, 10 f-stops, then F = 10, giving SN = 8.) combining the constant terms gives the approximate (and much simpler) equation of: Actually, that simplifies the formula you seek to: F = (1 / log 2) * (3/7) * (SN - 1). A quick and easy method is simply to divide the OD by log 2. Where T = transmission rate, OD = optical density, and SN = shade number.įor example, shade #10 gives SN = 10, OD = 27/7, and T = 0.000139, or nearly 13 stops! (calculating stops merely involves using base 2 instead of base 10 for the optical density. I've been looking around for this information too! I finally found the answer (after stumbling across your question first) at this website.
