Hello all,
New to the forum, I have a crossfire Pro with the razorweld cut 45 with THC.
I have had the machine up and running and cutting for about 6 months now and made plenty of cuts. Last week I was cutting .25in and I kept having and issues where it would start to pierce the work piece and the arc would go out or during a cut the arc would go out and give me the message “Cutting voltage lost during cut”. I was using all the same cut parameters that I normally use on .25in, .06 cut height, .08 pierce height, 1 sec cut delay, 30ipm, 40 amps. I tried grounding the the slat bed, water tray, and even the work piece itself. Changed out consumables as well.
I eventually was able to finish cuts by decreasing my pierce delay by 50% and increasing my feed rate by about 20%. I can also take the plasma torch out of the torch clamp and try to cut manually and the arc go out rather quickly even with a good ground.
Any input would be great, Im just confused why it would act different all of a sudden after making so many cuts on .25in without any issues.
Thanks in advance.
