Solution: The Hot Gas Bypass Valve (not shown in the Parts List or Assembly Diagram) needs to be adjusted. This adjustment should only be done after consultation with our technical support service at: 1-800-444-3353.


Hopefully this is my issue. I will call tech support. Hopefully Harbor Freight's tech support is as good as Torchmate's.....but I'm guessing it wont be. lol

has anyone spoke with HF tech support about this? my replacement units freezing up even after i adjusted the fans kick on temp setting.

On mine, you can look at the site glass on the coelsecent filter. If it's full, empty it by hand and figure out why it's not auto draining. Or just go ahead and remove the cover and bowl and look. 5 minutes will cure your curiosity.

My plasma indeed has a filter, but why would I get good pressure straight from the compressor and bad pressure from the HF air dryer?

I have a hankinson dryer and it will pop the drain when its full, it takes weeks. If I shut the air off and pressure the lines down it will drain after the pressure is zero. Is your air dry? hook up an air gun to it and spray it on a papertowel.

jatepper Well, everything was going good today until I was about 3/4 through the sheet. I got that loud ripping noise and thought I blew either my tip or electrode. Electrode looked good, so i just replaced the tip. Started cutting and all was good for a monute or so and I heard the ripping again. Looked at me plasma cutter and put the air on purge. It was only getting aboit 40 psi. Did some troubleshooting and bypassed the air dryer and the pressure was good again. Anyone knows what gives? There is something in the dryer restricting air flow.
07-15-2011 09:29 PM
jatepper Yup, I bought one too. I did it online and used 20% off, so with shipping ($1.99) it was $9. Better then me driving 30 minutes to my closest store

The Harbor Freight air dryer has a good reputation. I have been using the HF auto compressor drain....it drains the tank for a few seconds every time the compressor cycles. It was about $15, and I have had it in use for 2 years...works great.

Thanks for mentioning that Jim I went and picked up one today, it was only $8.99 so I couldn't pass it up!

jatepper Hey, I get it now! Thanks for that little tutorial. Thank you as well Wayne!
07-15-2011 09:33 AM
jimcolt Wayne has it right. Here it is in simple terms.

Air is compressible...water is not. So whenthe compressor intakes a large amount of air on a humid day....an increases its pressure and packs it into a tank.....you have a large volume of high pressure air.....as well as all of the humidity that was originally in the air.

When humid air is released.....as through an air hose nozzle...or in a plasma torch....the pressure rapidly drops, which causes a cooling effect on the air....which causes the moisture in the air to form larger droplets....separating the water from the air. Often you can spray an air hose from a compressed air system on a humid summer day...and see a fog coming from the hose.

The air dryer is a regrigeration unit that cools the high pressure compressed air (before it gets to your plasma or other air tool), making the water particles into larger droplets...this cool air is then fed into a coalescing filter....which basically is a centrifuge that spins the air rapidly.....the water droplets are heavier than the air....so the centrifuge effect slings them to the ouside of the filter bowl where the water separates from the air. The bottom of the coalescing filter bowl either needs to be drained periodically or has an auto drain. This effectively removes the humidity from the air.....now it can go to the plasma cutter relatively dry.

I'm already here, so I'll answer for Jim...

The air goes in and passes through a series of coils and a radiator looking thing with a fan. From there it goes to a big tank and out. On the bottom of the big tank is a coalescent filter and since the air is so cold, the air turns to droplets, and droplets fall out at this point.

The coalescent filter has an auto drain. In my setup, it will purge nearly every compressor cycle, so make sure the drain is pointed away from something you don't want getting wet.

If it notices the air temps creaping up, the fan will turn on to cool both the refrigerant and the air.

I did make a quick adjustment to mine though. Run yours first to see if you need to make the adjustment. There is a thin line between the fan cycling and running all the time.

Now the air is still ~145*C going in, but the air going out is around 0-2*C, which is still low enough for the dew point and to pull water.

I ran my plasma on purge for an hour straight. The compressor cycled 4 or 5 times and the air temp never got higher than that 0-2*C...

Basically I set the fan low enough that it still cycles when the compressor is off. If you are looking at the control box (white box under the temp gauge), there are three phillips head screws. One in the top right, and then two in the middle'ish. The one on the left, was set at around 18, leave it. The one on the right was set at 10, I left it. The one on the top right was all the way down, so I simply raised it up to about the first white line.

Left side of the box is for the compressor. Right side is for the fan. The screw on the top right I'm assuming is a fine adjustment for the one below it. They both do the same thing, trigger the fan on/off setting....

What about running an M-26 or M-60 motorguard filter in conjunction with the refrigerated air dryer? Is that overkill? What is the difference between the M-26 and the M-60?
This is how I have my setup and because of it I have no drains to fuss with, either auto or otherwise. No moisture in the tank means it can't rust, either

I don't think I bought mine with the extended warranty?
07-01-2011 05:37 AM
jimcolt It is a coupon that came in a flyer in the mail a couple of days ago. It says order online only.

I have heard nothing but good reports from owners of thes units.
