Cut some 1/2" plate with my old TD 38.
I used to hate this cutter and we never used it
now i learned good power source and dry air is the key to make any decent cuts(or any cuts really )
im using harbor freight air dryer and old NAPA Vertical Air Compressor,
60 gallon capacity, 22V, 5HP motor
Anyway i cut engine mounts for mini excavator i’m re-powering
moving really slow 3 IPM feedrate and maxed out machine @30 Amp
design,test cut on thinner metal
and test fit



first 1/2" cut
bad consumables (bad bevel)
not enough pierce delay


second cut
