How difficult is it to modify the heating unit to 110V so it
will heat and operate at a reasonable rate?
By simply changing the plug from 220 to 110, you effectively cut the
rating of the heating element in half, so it produces only half the
heat. Your options aRe:
obtain a replacement heating element designed to deliver the
correct wattage at 110 volts,
or give the machine the 220 volts it wants. That could be either
by placing it somewhere where you’ve already got 220 (such as a dryer
or range circuit in your home), or by using a step up transformer.
To use the dryer or range circuits, you’d have to change the plug
again, and since these circuits are normally specialty plugs, this
will be somewhat clunky, especially if you use the circuit for it’s
original purpose as well. The plugs used for these higher amperage
devices generally are designed so you have to push in and twist to
plug in the thing, so switching some of these from one to another can
sometimes take a bit of strength. Depends on the plug type, and how
easily you can access it.
You could, if you’re handy (Or have an electrician do it if you’re
not) run a new 220 circuit for the thing, as it’s certain your home’s
fuse/circuit breaker box does actually have 220. You just have to
get it where you need it, or you could tap off an existing circuit,
such as the dryer circuit. This is much easier to do than running a
new circuit, but you may then have to be sure to only use one of the
devices at a time. Being basically lazy myself, I run my laser
welder off a second plug I wired off of my dryer circuit. Just
means I can’t use the laser when the dryer is running.
The simplest solution, and most versatile for placement, etc, would
be just to obtain a step up transformer. These are made for exactly
this type of use. And that then lets you use any normal 110 volt
