Required parts
Nothing outstanding at this time.
Automatic Z zeroing
Ohmic sensing
Pros:
- Simple wiring torch needs a few accessories to make it work correct
- Pre-build modules avaliable relatively cheeply ($75 candcnc)
- What everyone else does
Cons:
- Un-reliable with the water table
Touch off
Pros:
- Simpler that ohmic
Cons:
- Err?
Torch Consumables
The torch is a T45m hypertherm machine torch.
Standard
- Deflector P/N: 2206732
- Retaining Cap - Ohmic P/N: 220719
- Nozzle P/N: 220671
- Electrode P/N: 220669
- Swirl Ring P/N: 220670
Fine Cut
NOTE: These parts are for a t30 unshielded torch, they are compatiable with the T45m when it is run at a setting lower than 30A and cutting materials thinner than 3/16". Ohmic sensing will not work with these parts installed.
- Deflector P/N: 2206732
- Retaining Cap - Ohmic P/N: 220483
- Nozzle P/N: 220480
- Electrode P/N: 220479
- Swirl Ring P/N: 220478
