There are settings for both gas pressure and flow rate. These can vary depending upon the welding position, metal type/thickness, type of gas used, and conditions (wind, drafts etc.) My welding instructor told us that 20-20 is a good place to start (20 psi, 20cfm flow).
It is the one lettuce that doesn't have a lot of Vitamin K. One cup of iceberg lettuce contains only about 13 micrograms (mcg) of Vitamin K. This is a low amount and should be safe for you to use as part of your diet while on CoumadinÂ® (warfarin). Thanks for writing, Timothy S. Harlan, MD, FACP. Dr. Gourmet.
Vitamins. While iceberg lettuce is relatively low in nutrients, darker greens contain folate and vitamins A, C and K. The exact amount of vitamins depends on the type of green. A cup of raw kale will provide you with more than a day's worth of vitamins A, C and K, as well as a small amount of folate.ark green leafy vegetables can also be good sources of calcium, iron and potassium. Each cup of raw kale provides 15 percent of the DV for calcium, 8 percent of the DV for iron and 14 percent of the DV for potassium.
