The Torchmate CNC plasma cutter (also known as the Plasmatron) uses a Hypertherm PowerMax85 plasma torch as its cutting tool. The torch is carried on the robot gantry in a vertical orientation. The cutting tip consists of an assembly of five parts. It must be assembled by the user and if it isn't done correctly, the machine will fail to cut or it will cut poorly.
Instructions for how to pick the nozzle and the correct speed and power settings are located here
The Torch Parts
Nozzles
| |
|---|---|
| 45-Amp large format nozzle (copper) |
| |
|---|---|
| "Fine-Cut" small format nozzle (copper) |
The part that effects the cutting action is called the nozzle. They are made of copper. There are four alternatives: one small format (called "Fine-Cut) and three in a larger format. The thickness and material of the workpiece determines the choice of the nozzle, and machine settings are set accordingly.
The Fine Cut nozzles have hemispherical tips and they are shorter than the large-format nozzles. They can cut sheets between 0.024" (24-Ga) and 0.134" (10-Ga). These may be run at either 40 or 45-amp depending on the range of thickness.
The three large-format nozzles come in 45-Amp; 65-Amp; and 85-Amp sizes. They have conical tips and they are taller than the Fine-Cut nozzles.
Most often the 45-A nozzle is used. In carbon steel, it is appropriate for sheets 0.060" (16-Ga) up to 1/4-inch thick.
Retaining Cap
| |
|---|---|
| Inserting the nozzle into the retaining cap. Cap and nozzle inverted. |
| |
|---|---|
| The torch assembly retaining cap (copper with plastic sheath) |
The nozzle retaining cap holds all of the pieces of the assembly in a single package to screw into the barrel of the torch.
Nozzles are inserted into the cap from the open end that doesn't have the copper male thread on the outside. The nozzles rest of a step inside the hollow space in the cap and stick out through the bottom (threaded end) of the cap.
Electrode and Swirl Ring
| |
|---|---|
| Swirl ring (plastic). Part shown is for a Fine-Cut nozzle, with a single row of holes on the bottom circumference. |
| |
|---|---|
| The torch electrode (copper). One size fits all. The tip visible normally points down. |
