Choice between Fiber laser or CO2 laser ?

Choice between Fiber laser or CO2 laser ?



We are searching for new Laser machine. Now we are having Trumpf 4KW CO2 laser machine. We are cutting more than 95% mild steel and hardox in thickness range from 0,12in (3mm) to 0,79in (20mm). In future we would like also like to cut 1in (25 mm) on the laser so we are thinking about 6 KW laser machine. Now is very popular fiber technology but we don't know if this technology is also so appropriate for thick mild steel..or we rather stay on CO2 technology ? Does anyone have experience with 6KW fiber lasers ? Does it CO2 technology abandons? How is with the cost comparison between fiber and cO2 laser if someone has some data maybe ? And then also possibility of cutting mild steel with nitrogen in lower thickness range, fiber lasers have high speeds in this case but what is with the gas consumption ? And how is with spare parts with fiber lasers and maintenance is it cheaper than by CO2 lasers and how much ? Maybe has someone experience with these things and can help with some advice or data...and which company you recommend ?
