Fantastic 18 Gauge Nichrome Wire Galleries - Hello dan, sorry to be the sort of pest, every other query if i may additionally. Does the heating detail ought to be in three pieces 35.4 inches each or can or not it's one piece this is 106.2 inches in duration? Thank you, -mike.

Hello blaine, kanthal a1 is rated for 1400°c (2552°f) and so should be capable of face up to the temperatures required to soften copper. In fact i often take my warmness treat oven to 1080°c (1975°f) with kanthal a1 running @2000 watts. . You'll need to get your watts up if the loading is sizable. I don't recognise what the firebrick is and the scale the crucible. I don't assume pulling 22 a through some 12 gauge twine could be a hassle. The quickest way to soften copper is with a gas setup, however there can be reasons for going electric which includes co emissions. Top luck! Dan.

Hi james, i can best remark from my enjoy with 18 gauge. The trendy 18 gauge factors were going for walks in my oven for multiple years, whereas the imported 22 gauge ones i were given from ebay failed in much less than a year. If we dared to assume, it makes feel that heavier cord can be greater long lasting. I've worked with some makers that went with 16 gauge and their ovens are running quality. Imho 18 is first-rate, sixteen is better. ;-) Dan.

The method for floor modern-day load for kanthal a-1 is between 14 and 32 watts in line with squareinch of cord surface place, the better the temperature you would like to operate on the lower the present day load potential. To get the correct wire gauge you want to know your intended voltage and amperage (up to you, however you may need the proper ohms per foot to reach your supposed amperage) the system for floor region of a cylinder is as follows (i'm now not which includes the pinnacle and backside of the twine because it isn't important for our case) (2 x pi) x radius x top. Example 16awg cord has a diameter of .0508 first divide .0508/2 = .0254 radius. Then multiply {(2 x pi) 3.14 x 2=6.28} .0254 x 6.28=zero.159512. Now you must parent out how many feet of wire you need to reach your favored ohms. For this discuss with the opposite design notes: referenced above. For smooth reference i'll use the 2200 watt @ 120v layout of 2 detail runs of 38.5 feet each. First we need to convert the total length of each wires to inches to gain the entire floor region of both runs, which is as follows 38.5 x 2 = 77. 77ft converted to inches, 77 x 12 = 924 inches overall period. Now we take our in advance calculation of .0254 x 6.28 = .159512 and multiply this with the aid of our 924" to get our overall floor vicinity in rectangular inches. .0254x6.28x924= 147.389088 sq.In. Now that we've got our general surface place we will decide our floor loading for our twine. Kanthal's furnace-mini-handbook pg 9 figure 4 (a. Kanthal a-1 spiral wound in grooves) suggests for our desired temperature of about 1830f our maximum recommended surface load is 19 watts in line with sq.In. So now we take our total of 147.389088 squarein and multiply through 19. 147.389088x19= 2800.392672 watts floor loading ability. Whilst deciding on cord gauge it's exceptional to stay 10-20 beneath the max surface load in an effort to have the longest usable lifestyles of the element.
