I want something that will cut 1/4" steel without any problems. I was looking at the Lincoln Tomahawk 375 and the AHP AlphaCut 60.

I like the fact that the Lincoln is easy to get parts for at my local welding shop, but the AHP is cheaper and has an additional 35 amps of power. Any recommendations? I am not looking at these exclusively, so if you have experience with another machine I am all ears.]]>

Oxy-propane or Plasma Cutting? http://w2ww.cypressweld.com/index.php/en/weekendwarrior/oxy-propane-or-plasma-cutting http://w2ww.cypressweld.com/index.php/en/weekendwarrior/oxy-propane-or-plasma-cutting
Oxy-Propane Pros:
-300 to 500 dollars for a high quality set(depends on where you look)
-Propane is MUCH cheaper and easier to find and buy than acetylene
-Propane is less volatile than acetylene
-Much more "portable" than a plasma cutter
-can be used to heat and bend steel

Oxy-Propane Cons
-Uses slightly explosive gases
-need to refill gas bottles
-slower than plasma

I know that propane is used instead of acetylene in the industrial world because of the higher cut efficiency over acetylene because it can achieve higher BTU's than acetylene. I wouldn't mind the slower cut speed if I can heat and bend steel as well.

Hypertherm Powermax 30 AIR Pro's
-Self Contained(has a built in air compressor)
-Fast and clean cuts
-Can sever cut 5/8 plate
-Dual voltage

Powermax 30 AIR Con's
-Cost(almost $1500)
-Needs electricity

Any helpful answers would be greatly appreciated. I'm leaning towards the torch, but I might still get the plasma cutter. I'm leaning towards the torch because it is cheaper and it has multiple uses(and the cost of the steel is about $3500)

Starter Plasma Cutter? http://w2ww.cypressweld.com/index.php/en/weekendwarrior/starter-plasma-cutter http://w2ww.cypressweld.com/index.php/en/weekendwarrior/starter-plasma-cutter A big thanks to everyone who answered my Oxy-propane vs Plasma question. I am now steered back on the plasma path, so to speak. I need a plasma cutter for my shop, but I don't want to drop $12-1600 on a hypertherm(yet). I know that hypertherm makes the highest quality of plasma cutters, it's just that they are a little pricey for me right now(saving for my big project!). On the other end of the spectrum, I don't want a crap ChiCom machine either. Do you have any recommendations on starter plasma cutters(ones I can do a ton of projects with before replacing)? My budget is about $1000 (+/- $2-300) for the plasma cutter and the air compressor(getting a portable one)

Playing with different size plasma nozzles. http://w2ww.cypressweld.com/index.php/en/weekendwarrior/playing-with-different-size-plasma-nozzles http://w2ww.cypressweld.com/index.php/en/weekendwarrior/playing-with-different-size-plasma-nozzles
Trying different air pressure and amp settings..

Mechanic416 (aka George) was kind enough to help me get started in the right

Think I need to order a set of nozzles and tips just to have some on hand..

Has anyone seen a chart or something that lays this out?

air pressure versus amps?

George,, You have a set I can order from your shop?

Can see a video or two coming out of this .....

Oh Yeah,, anyone looking for a set of training wheels/ circle cutter attachment for your plasma should talk to George..

He custom makes each to fit YOUR machine..

Really nice with a swivel built in to the mount.. You don't have to walk around the table or turn the metal to cut the circle...

Fun with a hypertherm 600 http://w2ww.cypressweld.com/index.php/en/weekendwarrior/fun-with-a-hypertherm-600 http://w2ww.cypressweld.com/index.php/en/weekendwarrior/fun-with-a-hypertherm-600 He wanted to take some time and see if we could figure it out. Well the no air error cleared and the safety error on the torch light up. After changing all the consumables that code went out and he fired it up, cut the pieces out. went to cut some braces and the overheating error code was light up it wasn't clearing. So I called the tech services the guy said that sitting in the sun It was sunny and about 73°F the units fan was working. He says well you can try getting an umbrella for some shade on the case as the aluminum ones heat up fast and trip the board thermostat. Well I will get one of the HF Bistro umbrella's tomorrow. What I did do was put a fan on the ckt board side of the case on high with both it and the internal fan it cooled off and we ran it the rest of the day.

Haven't used it much, but never had so much trouble with the unit. when it works it works well. And I understand that the inverters are even better.

So if your plasma is acting up try a fan on the case or its own umbrella!;)]]>

While working on the mod's to the kids smoker had to do some edge to edge cutting of 1/8" sheet. Using the 8 foot aluminum yard stick takes two people to get it set up. While I was picking up HF version of the adjustable C welding clamp yesterday I came across the above. So with my trusting 25% off coupon photo on my phone I picked up one. For thin stock it will require something to keep the pads from sliding past the edge of the metal. Has a very nice edge for cutting the width of sheets. They also com in smaller lengths too.

But this does close up to nothing with just the excess hanging out.;)]]>

Plasma Cutter? http://w2ww.cypressweld.com/index.php/en/weekendwarrior/plasma-cutter http://w2ww.cypressweld.com/index.php/en/weekendwarrior/plasma-cutter I see a lot of 50 AMP Inverter Plasma Cutters advertised for under $300. Are they worth it?
I have seen some good reviews on Amazon and you tube.

How to have dry air for your plasma cutter... http://w2ww.cypressweld.com/index.php/en/weekendwarrior/how-to-have-dry-air-for-your-plasma-cutter http://w2ww.cypressweld.com/index.php/en/weekendwarrior/how-to-have-dry-air-for-your-plasma-cutter I Am an ASE Certified automotive painter, one thing I have found is that most people don't know why they have water in their air supply. All compressors make water, but more importantly they make steam.... If you take a supply tank 80 gal upright or what ever, and put a 2 foot pipe and a water trap or some other filter you will have severe water issues 50 ft later at the air tool....Why is this you ask because it is hard to filter steam!
If you have ever looked at a water trap, you may have noticed it is not much more than a cup with a drain at the bottom and an inlet and outlet at the top....If you have steam at the inlet and 3 inches across is the outlet where do you think the steam will go! Just remember it's called a water trap, not a steam trap!!!;)
Take the same compressor and put 50 ft of line or pipe and add a harbor freight cheap water separator and you Will have DRY Air! It takes 50 ft for the steam to condense to water...once you have water, you can easily separate it from your air supply.

I use nothing more than a 50 foot air hose strung on a wall in a down hill zig zag pattern, with a simple water trap a the end and then my pressure regulator. I get water at the trap but nothing after it.
To prove I have no water in my lines after the filter consider this, I have a water trap on my plasma cutter as well and have used it for over 7 Years, It is dry as a bone and has never been opened , yet i have to regularly open up my primary to empty the water out!!!
Their is nothing wrong with using filters..but they are meant for small amounts of matter not doing the work load of a water separator!]]>

Cutting clean "fish mouth" in steel tubing http://w2ww.cypressweld.com/index.php/en/weekendwarrior/cutting-clean-fish-mouth-in-steel-tubing http://w2ww.cypressweld.com/index.php/en/weekendwarrior/cutting-clean-fish-mouth-in-steel-tubing I have a tubing notcher, but the small diameter thin tubing knocks the teeth off hole saws. I even found some expensive hole saw blades that have 15 teeth per inch, but I get the same result. Not as bad, but loose too many teeth. I only get four or five good cuts per blade. The larger diameter tubing cuts real nicely.

I am feeding at the slowest speed I can and the RPMs are as slow as possible. I have experimented with every speed range combination on both. Can't seem to get around it.]]>

Plasma cutting stainless - can I get a clean edge? http://w2ww.cypressweld.com/index.php/en/weekendwarrior/plasma-cutting-stainless-can-i-get-a-clean-edge http://w2ww.cypressweld.com/index.php/en/weekendwarrior/plasma-cutting-stainless-can-i-get-a-clean-edge
Do any of you have any tips? Would nitrogen help?

If there aren't any suggestions, does anybody know where I can find more effective sanding belts and drums? Ideally I need Ø1.125" drums and 4x24" belts. I have been told that ceramic sanding media will work well, but I can't find it in my sizes.

Thanks in advance!]]>
