@appliguy - No worries, glad we were able to clean up that misunderstanding. Now let's go play with the other children, shall we? *LOL*
@Mr.X - Don't know if your only referring to max power for 15amp only sockets, but American homes have 20amp sockets as well. Usually one finds these circuts for high power draw appliances but not 220v, such as air conditioners, refrigerators, etc. I like to run my ironers, presses, and even irons off the 20amp circuts as it gives a bit more wiggle room in terms of power.
In general found that by "vintage" steam irons one didn't like anything say before the 1960's or 1970's as they didn't put out nearly enough steam to properly iron things unless they were dampened. Well if one is going to go through all that might as well stick with dry ironing. By about the late 1950's or so appliance makers seem to have come up with ways to produce more steam and things got better. That was until some darn fools decided irons were getting "too" hot and wattage was reduced.
Cloth cords versus plastic:
Most of my NIB vintage irons with a cloth cords state not to twist the cord into "loops" and wrap closed (as they usually come from the factory) after use, but to loosely wrap around the iron after it has cooled. Apparently the former method wears out cloth cords faster and or causes fraying.
Had to replace the cloth cord on one of my Presto "Vapor-Steam" irons and am here to tell you yes, the stuff frays and creates "dust" as cut and messed about to put on a new plug for instance. Became worried about this out of fears of Asbestos which was routinely used for insulation and other purposes back in the day. Happily vintage replacement appliance cord sets for irons are easily found at estate sales or Fleapay, so stick to ready made.
This brings up another point, if replacement appliance cord sets were so widely sold there must have been a great need. So either the irons out lasted the cords or the latter could be counted on to wear out.
Have found the earlier black/white cloth cords a bit less durable than the later blue and other colours from the 1960's or so.
