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.
There is 3.445 mcg of Vitamin K in 1.0 medium of tomatoes (red, ripe, cooked). The recommended USDA amount of Vitamin K for adults 19 and older is 90 mcg/day. While on Warfarin, you should consume the same amount of Vitamin K daily. The USDA recommends that adults get 90 mcg of vitamin k daily. If the only thing you ate today were tomatoes (red, ripe, cooked). You would have to eat 26.12 media in order to get your 100% recommended daily value of 90mcg of Vitamin K.
