Ajan Plasma Cutter – Frequently Asked Questions

We often have a lot of customers who are considering whether making the leap to purchasing an Ajan Plasma is worthwhile. Whether it is their first plasma, or maybe replacing an older machine. The Ajan is a powerful piece of equipment, but as a considered purchase, you need to be sure it’s right for you. Understandably, we therefore hear a lot of the same questions from our customers.

Plasma cutters by their nature generate a large volume of heat. The gantry rails of the Ajan are completely separated from the cutting bed. This means that any heat generated from the plasma cutter will not cause any heat distortion to the gantry rails.

With a capacity of up to 200mm thick material, therefore the loading and unloading of such thick, heavy material could cause a lot of vibrations through the cutting bed. Again, due to the separated gantry rails, these vibrations will not affect the servo drive motors, or the overall alignment of the machine.

The machine also has extra wide rail runners for increased accuracy and stability. This helps to eliminate any potential issue of crabbing when the cutting head is moving. Each axis has its own independent servo drive motors for increased accuracy.

The Ajan’s heavy duty cutting bed comes with zoned extraction too. The slats across the cutting bed are supported in three places for added durability.

The Ajan Plasma has two power sources to choose from, 130 amp or 260 amp. The 130 amp, which has a cutting capacity of 25mm. The 260 amp power supply is capable of cutting up to 65mm material.

For thicker materials (up to 200mm thick), there is an optional, interchangeable Oxy Fuel torch head. This interchangeable head sits in the same position as the standard plasma torch. This means there is no loss of capacity along the Y axis when cutting.

The power requirements are 100 amps per phase, and should run from a 125 amp breaker.

The gas requirements are as follows: Oxygen (O2) and Air for standard cutting. Nitrogen as a pre-flow gas. If you’re intending to cut any Aluminium, or Stainless Steel, you would also need H35 (Hydrogen / Argon mix). If you’re using the optional Oxy Fuel head, this also utilises Oxygen and Propane to run.

Lastly a 10 bar screw compressor will be needed for cutting and to run the extraction and filtration system. This compressor must be fitted with a drier. This will greatly improve cut quality, and also extend the life of your Ajan consumables.

Service is one of the main reasons that we (Selmach) partnered with Ajan. 95% of the machine is made in house, giving complete control over the manufacturing process.

To complement this, we offer a 24 hour breakdown support line. Firstly, our in house technicians will try and diagnose and support over the phone. However, if an engineer is required on site, we aim to arrange a visit within 24 hours.

Life expectancy of the consumables is very hard to predict. There are so many factors and variables that can effect the life span of consumables. On average we say 500 – 750 pierces per consumable.

One of the great features of the Ajan Plasma, is that all of the consumable components are entirely separate. If one part blows or burns out, you don’t need to replace the entire set.

The software provided on this machine has a simple shape library where you can quickly nest one-off parts. This is also where you can select optimise hole to run on your nest. This is where the machine will slow down to give you the best hole quality.
