I broke down and bought the Eastwood dual voltage gun. I started with the hf gun. I wanted to give my opinion on both. I searched and searched the Internet before buying the Eastwood and have read mixed reviews. Read tid bits here and there about this and that. Kinda broken up info if you will.

HF gun
Pros
-cheap
-decent starter gun
-easy to work
-has an led to tell you when the unit is on and also a seperate light to let you know it's energized
-can run to a local hf and buy one the same day
-very controllable
-has a regulator on the handle
-comes with a water filter
-if you break it, it won't cost much to replace
-it's a decent starter gun to see if its something you want to get into
-wires are made plenty long enough (eastwoods too short)
-there's several mods you can do to it to make it a much better gun...but the remote mount cup seems like a pita

Cons
-cheap. Drop it once and it will likely break. Mine did but its an easy fix
-doesn't shoot a consistent and good pattern.
-when the powder gets low in the cup it starts messing up
-if your shooting down sometimes it will dump a nice lump of powder on your part
-it's hard to find extra powder cups. Stupid thing is hf sells powder in a cup that looks identical to the powder cup that goes on the gun but the threads are just that much smaller that it won't fit. :(. Dumb. I found our if you wrap the threads with tape a little bit, it will screw in.
-the gun and the box are alot bigger than they need to be
-needs tweaking to make it better, it's liveable if you have patience

Eastwood gun
Cons:
-does not come with a regulator or a filter
-the ground on the handle is not fully grounded when you screw a fitting or a water filter on. I had to add a washer
-the tip or diverter that comes on it spreads the powder out like crazy and wastes a bunch. A quick fix was rob the small one from the hf gun. The electrode is not threaded where the tip goes on either. The tip just slides on. Think that will loosen up quickly. Super glue to the rescue when that happens.
-the cup will leak out the box. It's cheesily siliconed sealed. The silicon was peeling out the box! I already knew about this issue. I went ahead and cleaned the silicon off of it and sealed it with clear two part epoxy. Here's something I'm gonna tell you that no one else has mentioned (that I've seen anyway). You think by looking at it that a Phillips screw and the silicon hold the threaded top for the cup on. Nope. The plastic tubes are threaded and screwed into the gun body. The threads are kinda crappy too so be careful. Use a rag of some pliers to grab it and loosen it.
-the wires are too short
-there's no on/off switch nor are there power or indicator lights. Kinda crappy on their part in my opinion.
-shoots alot more powder with the same air pressure. Seems much more consistent.
-oddly, seems like the powder sticks better and goes on better. May be higher voltage on the high setting vs the hf gun. The spark does seem stronger. I dunno. Just works better!

Pros:
-looks and feels better quality
-small
-lighter and more balanced
-the power supply is 1/3 the size of the hf
-shoots more consistent. I actually changed the big diverted than came with it to the small hf one and it shoots like a dream (compared to the hf anyway :lol)
-has dual voltage
-a performance kit is available from Eastwood for it
-Eastwood has great customer service and backs their products
-I bought it for $129 shipped from Eastwood on there eBay auction. No idea why it was that cheap
-all their powders come in cups that screw right onto the gun. You can also buy extra cups cheap. Yes! That's a big plus for me right there.
-overall I like this gun alot more. I'm thinking about buying one or two more and put quick connects on the wires to make swapping colors easier. I could just buy single voltage guns for cheaper and use them. The box is what makes it dual voltage.
-has a thumb button to energize it compared to the foot pedal on the hf gun

Here's a comparison

When I wrote the above I haven't had to use the dual voltage yet. I did the flywheel side of the case afterwards. I could not get powder into the deep crevices until I turned it on low voltage. I guess it worked. I didn't find any dry spots.

anyone try one of the infrared curring lamps from eastwood or anywhere else? basically looks like a lamp on a stand and you can move it around to cure all of a bigger object.. such as a frame. sounds good, but does it work?

I dunno. I almost bought one but I'm skeptical of it. It probsbly does work but I'd imagine you'd see curing lines maybe. I'm not sure.

I will be looking for your review then. I am skeptical of it working too, but i would also like to powder my own frames rather than send them off

Will do. I'm still trying to decide on a sand blasting setup. I have a pot blaster, but don't really like doing that in the yard. However, my compressor really isn't big enough to support a blasting cabinet.

It gives you two voltage settings. The theory is that you can spray the first layer at low voltage and then spray a second layer at the higher voltage.

Personally I found that its best to spray the second layer with the item heated to the thermal setting temperature of your powder, which makes the voltage setting almost irrelevant.

But I'm no expert and have only sprayed about 10 times so far.

Honestly, I've tried the lower voltage and I don't see any situation where it helps. If I buy another, it will be the single voltage Gun. I keep it on high voltage as it is.

The single voltage gun operates at 11kV.
The dual voltage gun operates at 15kV and 25kV.

So, there is a bigger difference then just the dual voltage setting. Not sure if its worth it, just FYI.

Well get the dual voltage then. The extra voltage does defiantly help. I noticed my hf gun is weaker so the powder does not stick nearly as good.

I have the cheap O HF gun and do not have any negative comments about it. I've been coating things for a few years and pre-heating the part seems cures many of the application adhesion issues/problems, this especially true on parts that have been in service with oil and grease bake those for a few hours at 450-500 cool wash in lacquer thinner and bake again cool clean heat em and shoot em. I shoot ALL of my items preheated to curing temp with fantastic results.

Been awhile since i was on here last. I just started powder coating been using a hf gun with good results so far. I seem to have to recoat multiple times to get a smooth look cause i tried a few parts with a single coat and once cured they looked horrible. I cure until it starts to melt then re shoot then cure and sometimes re shoot. I have a hopper setup on mine. Works well except i loose some powder out of where i put the fittings into the cup.
