Got one of these: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=91129
Works great, but want to modify it to work continuously, or atleast for a few minutes at very high current. Has anyone here done something similar? Any ideas?
Simplest way I guss is to drill a hole and use a spray bottle to cool the element. Air cooling probably won't cut it.
