How to Choose Plasma Cutter

There are several factors you need to consider when you’re planning to buy a plasma cutter. The factors include cut capacity, cut quality, reliability, ease of use, duty cycle and operating cost. The first step you need to take is to find out what kind of plasma cutting you plan to do. Are you planning to cut on a table? Or to cut by hand? Some of the plasma cutters of doing both. That is, going from handheld to mechanized cutting and back again.
Cut capacity
The rule of thumb is to choose a system with a recommended cut capacity that matches the thickness of the material you plan to cut 80% of the time. If you plan to cut 1/2 inch thick metal and occasionally cut metal that is a bit thicker, let’s say 3/4 of an inch, then you should go for a 1/2 inch system.
Cut quality
Cut quality is very important. Not only it will impact the quality of the finished piece, it will also save time in later stages of production.
Reliability
Generally, the most reliable plasma cutting systems are engineered with fewer parts, are manufactured to ISO standards, are adequately tested and use software instead of hardware where possible.
Ease of use
Some tools are easier to use than others. For an experienced user, ease of use will allow a job to be done more efficiently and faster. It also means that people with little to no experience can get good results too.
Duty cycle
If you plan to work away from your shop and or plan to move around a lot, then you need to consider the size and weight of the cutter. Fortunately, you can lightweight system without sacrificing power and performance nowadays, thanks to advanced engineering. Some plasma cutters come with technology that adjusts for different voltages and voltage variations automatically. This is good if you are planning to work off a generator.
Operating cost
The plasma consumable life varies significantly from one brand to another. Longer plasma consumable life does matter as it reduces the downtime for change-outs. Lots of brands use patented technology to extend the plasma consumable life.


Factors to Consider before Choosing Pocket Knives

Pocket knives are very important tools in our daily life. It doesn’t matter whether you just need to pare things or to go camping; this item is convenient to carry around. And when it comes to purchasing them, there is a wide variety of options. If you want to get the best, you need to consider several factors.

Length

The blade length is the first thing you need to consider.  And this will depend on your purpose of the knife itself. Most of the folding knives have blades between 2 and 6 inches long. If your purpose is to buy a simple one for everyday tasks, you should go for the standard one.

On the other hand, if you want to use a blade that can be used for the outdoors activity, especially heavy duty tasks, you should go for the single-blade larger folding knives.

If you are looking for a knife for slicing or self-defense, plain-edge single-blade is a good option.

Blade point

There are four kinds of blade point: normal, drop, tanto, and trailing.

The normal standard point is best for cutting, chopping and thrusting.

The drop point is best for utility and hunting.

The tanto point is used mostly in rescue and is considered as a fighting knife.

The trailing point is great for slicing and slashing.

Blade material

You will want a knife with a blade that can resist rust, maintain its edge and also, can be sharpened easily. The importance of steel strength and hardness it that both help in avoiding stress and permanent deformation on the blade. And like most other products on the market, you get what you pay for.

Handle material

There are several materials, size and style of the handle that you can choose from. If your purpose is to collect the dagger instead of using it, handle appearance will be very important. However, if your purpose is to use the knife for cutting, you need to make sure that the handle fits in your hand. This will increase control and prevents slipping.

If you are limited in budget, you can go for the rubber or plastic handles. They are affordable but not very durable.

The  bottom point is that focus on the above mentioned details to own the best pocket knife for you.


What to Know About Mig Welder

Are you thinking about getting into welding? If you do, before purchasing any equipment, you should ask yourself what kind of welding you are interested in doing. Most welding machines are capable of making most joints in metal. However, they all have their own specifications. That is, they are better at some jobs than others. The most universal among them is the Mig welder.

The Mig

Let’s start with arc welders. Arc welders are tools that are used to make a weld using heat that is generated from high voltage electricity. There are several types of them, Mig, Tig, and stick. The difference between them is the gas shield. For the Mig welder, the gas shield is created by a cloud of gas released from a tank connected to the welder. The tank is filled with a mixture known as Metal Inert Gas by the industry.

The gas

The recipe for the gas varies. However, none of them will react with metal and add contaminants to the weld. The gas is pumped through the welding cable from the metal tank that either you had buy or lease. The gas comes out of the same nozzle that the welding wire is fed through. It literally creates a protective cloud around the arc as you weld.

The settings

A Mig welder has several heat settings that allows the welder to set the machine to just the right power to get a deep weld with good penetration but not so much that burn a whole. It is likely that you will do this a few times before you get it right. Don’t worry. Even an experienced welder sometimes surprised and end up having to make last minute adjustments.

Other than the heat setting, there is also an adjustment to the feed rate of the wire. It will vary by equipment and project. Again, don’t worry. As you get to know the welding machine and your jobs, you will fine tune the feed rate. And yes, getting both the heat and the feed settings right before doing the job can save you time and money.
