My Tomahawk 625 has worked well for me except for two aspects: (1. The duty cycle of 3½ minutes cutting out of every 10 means that I have to watch my jobs with a stop watch and pause the job before I run into that limit, then wait for cooling and (2. The programmed in delays are a problem that has to be worked around or you’ll have big pierce holes.
At times I think that I’ll devote the Lincoln to general shop cutting and buy something else with a higher duty cycle for the CNC, but I never seem to pull the trigger and I continue using the Lincoln with good results.
The most frustrating aspect of it is the lack of cutting parameters from Lincoln. I wasted a lot of steel sheet because I had nothing to go by in the beginning. I did finally get some settings from Torchmate and I use the forum generated Razorweld spreadsheet in conjunction with them and that seems to be working well.
