Regretfully, we have decided to remove the Primeweld Cut60 machines from our list of compatible plasma cutters: http://www.langmuirsystems.com/plasma-cutters. The Primeweld units have become a popular choice among our user base, offering good performance and power at a very attractive price.
We have been hearing reports of FireControl freezing for quite a long time when used with these plasma cutters. We decided to do a thorough analysis of our past customer services tickets and have found that effectively all verified instances of interference have coincided with the use of the CUT60. While we cannot tell for certain, our best guess is that about 1/4 of customers that are using the CUT60 with our machines experience some type of interference problems. Normal remedies such as physical distance, installation of chokes, and use of a USB isolator have been shown to have only varying success.
As a manufacturer our goal from the beginning has always been to get people cutting in the most cost effective way forward. The CUT60 has played a role in that gateway due to its accessible price tag. However, we can no longer in good faith recommend these cutters with our machine from this point onward. For those that already own a CUT60 we will continue to do our best to support you as always. Thank you.
