We've dropped a new manual into the website for the Power Cool 300. http://www.everlastgenerators.com/do...Power-Cool.pdf
Also we've just completed a COMPLETE revision of the 250EX manual. Although there are many similarities to the other 2 units, we are now spinning out a manual for each power tig because some people were confused by the combined manual. I will announce when it goes up for all those wanting to see the latest changes in print form.
