What is plasma THC?
August 27, 2020 /in Hardware / Plasma CNC cutting machine is one of the most commonly used types of CNC machine. It’s used mostly for cutting Steel, aluminium and other conductive materials. Like any other type of CNC machine, plasma machine has it own specifics.
What is torch height control?
The torch height control uses arc voltage to maintain a consistent distance from the plate while the torch is cutting. This allows the system to maintain proper torch height regardless of variations in the material, or flatness of the cutting bed.
How do you use Mach3 plasma?
Basics of Mach3 plasma G-code The THC mode must be manually turned on (THC button is green). Use M03 command in G-code to start (Torch On) and M05 to stop (Torch Off) the plasma arc. Use code G31 for probing. Keep in mind that if THC mode is ON executing off the G-code will be stopped if Arc_OK signal is not activated.
What voltage does a plasma cutter use?
Primary power Several 30-amp plasma cutters, such as the Spectrum® 375 X-TREME™, operate using 120- or 240-volt power. If your input circuit has a 30-amp breaker, you even get equal cutting capacity at both voltages (with a 20-amp breaker, cutting capacity drops by 20 percent).
What is ARC stretch?
Arc stretching happens when the plasma arc is stretched either behind the torch, or to either side rather than being directly below it. This can happen after a pierce start when the arc is cutting too slowly and does not match the torch movement.
How many watts does it take to run a plasma cutter?
Take for example a typical PlasmaPart CUT 40 plasma cutter: Its power usage at idle is less than 10W with the internal fan running. An average standard 40A transformer based plasma at idle with the fan running consumes over 480W! That’s over 48X the power consumption before any cutting is done!
What can go wrong with a plasma cutter?
Unfortunately, consumables cause the most issues with plasma cutters. A nozzle is one consumable within a plasma cutter with air passages to help keep the torch cool. The torch will overheat if the passages are blocked, so fabricators ought to ensure the nozzle is clean before operation.
Why does my plasma cutter keep cutting out?
Water in the air stream will “put the fire out” in the torch. It can cause the arc to be erratic and unstable and may seem like the plasma cutter isn’t working correctly. Make sure at the least you are running a small disposable in-line water separator or upgrade to a desiccant system on your compressor.
How thick can a 100 amp plasma cutter cut?
30mm
The Pioneer Plasma Cut 100 Amp plasma cutter is designed for tough heavy duty plasma cutting applications with a max cutting thickness of 30mm and quality cutting thickness of 20mm.
