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

|TerraWombat||I would be extremely surprised if anyone on the end of that phone number knew what to do.|
|12-18-2011 05:25 AM|
Well, I hate to do it, but I reverted to the instructions. Under the "troubleshooting" section, it states...
Problem 7: Ice accumulating in the dryer, and/or a pressure loss through the unit.
Reason: This may be caused by the formation of ice inside.
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

|jmusser15||I think have a problem with my HF Air Dryer. I have yet to get any water come out of the Auto Drain tube from the dryer during short or extended periods of use. I cannot imagine my compressed air is that dry. Anyone else having this issue? Is there a setting in the machine that needs adjusted or is it junk?|

|monkeyworks||Check your plasma. I have the a60.it has an inline filter inside the machine. Check if you have one on yours.|

|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.|

|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|

|jatepper||Hey, I get it now! Thanks for that little tutorial. Thank you as well Wayne!|
|07-15-2011 09:33 AM|
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.

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.

Compressor, coalescent (in case the compressor spits anything out), HF, tank, M60, tool/plasma

Guess it sounds like I have it configured correctly then. Thanks.
|07-15-2011 08:50 AM|
You should have the dryer after the compressor and the tank....the tank should either have an auto drain (Harbor Fright has a nice one for cheap) or should be drained daily. A pariculate filter like the Motorguard is always a good idea between the chiller and the tool (plasma).
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.

I'm about to get my table running this weekend and I just want to make sure I am doing this right since I feel I may have it configured wrong....
I have my tank going to my HF refrigerated dryer and then to the plasma. Should I have the compressor motor going to the HR refrigerated dryer, to the tank, and then to the plasma?
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?

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.
|07-01-2011 05:18 AM|
I'm imagining you guys would recommend springing for the extended warranty/service plan on this?
|07-01-2011 04:44 AM|
The Harbor Freight refrigerated dryer is currently on sale for $299.....it is a bargain for that price as it is usually over $400.
