Even the simplest of plasma cutting applications — a hand held plasma torch — often use a method of torch height control. If an exposed nozzle on a handheld plasma torch cutting at 30 amps or higher contacts the plate even momentarily, damage can occur to the nozzle orifice that affects the shape of the plasma arc, affecting cut quality.

Newer technology hand torches use shielded torch technology, an electrically isolated copper shield that allows the torch to drag on the plate, maintaining the correct distance between the nozzle and the plate.

In high productivity mechanized cutting applications, dragging the torch on the plate is generally a non-acceptable means of controlling torch height.

Since the mids plasma system manufacturers have been using arc voltage feedback torch height control as a fairly effective means of controlling torch to work distance. Unfortunately, controlling torch height using this technology can be rather complicated, and puts another dozen or so setup parameters on the CNC machine operators list of tasks that are required to produce plasma cut parts with the best possible quality, with high productivity and low operating cost.

Plasma cutting uses a high temperature electric arc that is developed by applying DC current to an internal electrode negative and to the plate positive. Gas flowing around the electrode is heated to its ionization temperature, which increases its electrical conductivity, allowing the DC energy to form a superheated electrical arc from the electrode to the plate.

The arc is forced through an orifice in the plasma torch nozzle which controls the shape and velocity of this plasma arc, effectively controlling the energy and cut quality. A DC voltage can be measured between the negative electrode and the positive plate during steady state plasma cutting. In theory, this is a very effective method of gauging torch to work distance!

A typical plasma system height control has a reference voltage that is set by the machine operator. This voltage is provided by the plasma torch manufacturer and is different for every type of material, every thickness, and every plasma process power level. Any warpage or flatness issues of the plate on the plasma cutting table are automatically adjusted by this height control process.

Here are a few of them:.

After the arc fires, and the pierce is complete different timing for each material type, thickness and power level it is important that the torch indexes rapidly to the cut height again, different for each material type, thickness and power level in order to allow the plasma arc to stabilize before it gets out of the scrap lead in and on the actual cut profile.

There are height controls available today that are almost a completely transparent part of a CNC plasma cutting machine. In many cases the operator does not have any interaction to adjust any aspect of torch height control, yet the THC system is accurately set every time it is used.

These newest systems interact directly with the plasma system, the cutting machines CNC control, as well as with the CAM nesting software, interfacing all of these components with a simple Ethernet style cable.

Even if you do not have the latest plasma and THC technology on your machine, pay close attention to your existing Torch Height Control system, make sure your operators understand its features, how it works, and where to find the proper settings for each type and thickness of material being cut. It will be worth the effort!

Thank you. Hello Jim, I have been wondering if there is any table of relational dependence between metal sheet thickness, cutting amperage and speed. Cutting on 15 mm and thicker metal sheet we get a conical shape that I believe relates to the conical shape of the plasma fire. We want to loose it for at least metal that is 20 — 25mm thick. We use air for cutting gas.

The best. By default.

Our system was cleaned, has completely new refrigerants and vacuum so that we have good pressure and dry air. Our personnel are trained and capable to understand new operations, but maybe we are missing some important part of this process.

I have been in contact with Hypertherm and the manufacturer of the machine and we have yet to figure out what could be causing the issue. I have ohmed out between the torch head and the ohmic wire that attaches to the voltage divider ohmed out as goodI have also ohmed out the pilot arc wire in the lead set good as well. Has anyone had this problem, and if so, what was the ultimate fix?With the INOVA plasma cutting torch height control system, you can program more functions, set tighter parameters and get better resolution.

Can be used to improve cutting quality of bent and distorted metal plates. Regulator intercepts Z-axis vertical movement of a torch.

Bypass mode is provided for cases when control is unneeded. Main idea is to determine the current height by measuring a voltage of the plasma arc: the higher the voltage, the greater the distance.

To minimize effect of cross-talks and spikes there should be solid assembly and the plugin must not be located near any high-voltage or power circuits. Some installed shield full case or just to wires is also desirable. It's advised to galvanic isolate device as possible to protect low-current and logic circuits. All digital inputs are pulled-up to the high-level voltage by default so they are triggered by 0.

ATmegaP and Arduino pins notations are specified in the brackets. Also, note that your custom pinout should not conflict with other signals. It's recommended to use PC Arduino's A pins.

With this foundation in place, we can then explore the software workflow in later sections. These programs are made up of moves to numerically defined locations, coupled with actions M-Codes like turning on a plasma torch. Plasma Power Supply - The box that the torch and work leads connect to that converts wall power to the current required to cut metal. Combined with the work lead, it creates an electrical circuit that allows us to cut conductive materials such as steel, stainless steel, and aluminum.

Plasma Work Lead - The second half of the plasma electrical circuit. Commonly referred to as the plasma ground.

The plasma work lead is bolted to the machine bonding bar, and the work clamp from the bonding bar must be connected directly to the work piece being cut.

Plasma Consumables - The components that mount to the torch such as electrodes, shields, and nozzles. These are wearing components and will be periodically replaced. The control panel is connected to the plasma power supply via the machine interface cable. This cable provides control and feedback signals that allow the machine to ask for the plasma arc to turn on, and to measure the cutting voltage.

An axis is a direction of motion that the machine can travel along. There are stickers identifying each axis and their direction attached to the covers of the machine as a quick reference during operation. We can combine the directions of motion together with a reference point known as Home.

The machine can move to any position inside the work volumeand the distance from the current location to the Home point describes the Machine Coordinates MC. Here is a simplified drawing to narrow our focus:. In the image above, we are looking down on the table along the Z-Axis. There is also another coordinate drawn as G5X. This work-offset allows us to define a relative position anywhere on the table to cut our parts.

We export our cutting program relative to a local origin, and then tell the machine where that point exists. In the example drawing, the X and Y locations generated will always be positive values relative to the G5X system, even though the Y locations are negative in Machine Coordinates. Actual operation details will be explained later.

For now, just take away that we can weave our parts into a plate or sheet by moving this point around without having to return to the CAM software.

When the Emergency Stop Button is depressed, power is immediately removed from the servo drives halting machine motion and cannot be restored until the condition is cleared. After clearing the emergency condition, release the button by rotating or pulling the red cap, and repower the amplifiers.

You will be forced to rehome the Z-Axis, but it is highly recommended to rehome the entire machine X, Y, and Z axes before continuing operation.

If the torch hits an obstacle sufficiently hard, the magnetic breakaway releases to minimize damage. This condition is identical to an emergency stop.Torch Height control is the ability to automatically maintain a set distance of the torch to the work piece through the dynamics of the cut path. This is a big advantage and will save your money in consumables and also give you the cut the plasma cutter is capable of.

Torch height control works by reading the voltage that the plasma power source provides. There are factory presets already installed for ease of operation when cutting Steel, Stainless or Aluminum. A proper Torch Height control will yield great results.

This Torch height controller also gives a big advantage over slower and proprietary controls with no ability for the user to define presets. You will be able to cut exotic materials not defined in other controls.

The Star Lab CNC is a rigid high performance machine that will any plasma cuttable material down to a very thin 30ga. We are able to do this through a very tight tolerance tracking capability.
