Recently I posted in the Mach3 software section regarding issues with cuts being interrupted due to no arc firing.
For those unaware/considering future purchase Razerweld offers a Hypertherm “Style” torch upgrade to their plasma units. This torch is compatible with hypertherm consumables however Razerweld produces their own clone consumables.
The issue with the torch is it comes only with a hypertherm style “drag” deflector. This drag tip actually adds around 1/16-3/32" spacing from the nozzle to the end of the deflector. The idea being you can drag this on the work directly due to how it is designed/vented and it keeps the proper spacing for you.
When used for CNC however, dragging the tip across the surface of the work is not a great idea because any slight deviation could cause the work to catch and shift the material or worse the carriage could catch on the work straining the motors and screws.
The issue I encountered was when using the 1/16" shim, the spacing seems to be too great to properly ignite an arc at some points on the work. This results in letters with missing segments for example.
The solution I found, was to replace the drag tip from razerweld with a hypertherm machine style deflector which exposes the nozzle like most standard torches. Now I am able to get the proper gap and not risk grabbing the work and it appears to have resolved my issue.
For the 45 amp torch, the parts are interchangeable with the Hypertherm PM45 torch.
Fair warning, after speaking with razerweld, they informed me that the warranty is void if using parts from other manufacturers. You cannot buy the razerweld consumables yourself, your retailer needs to order them for you and I was not successful finding them anywhere online.
That said, the electrode, nozzles and swirl ring for the PM45 will also work in the Razerweld torch and is far easier to acquire locally than Razerweld consumables. (which was why i purchased the hypertherm style torch to begin with)
The part numbers are as follows
Hypertherm PM45 Nozzle - 220718
Hypertherm PM45 Deflector - 220717
Hypertherm PM45 Electrodes - 220669
It ran me $80 for 5 nozzles, electrodes and a deflector at my local store.
Hopefully this helps others in the future.
