text: <s>[INST] Single phase to Three phase drives for welder application Greetings, Has anyone every done an application involving a 1phase to 3phase drive application to provide power to welding equipment? I just took a call from a customer for 5 such units. Thanks. [/INST] Futher to my question; we are looking at adding a sine wave filter to the output of the drive to provide the cleanest possible power output to the welding machine. Is there anything else that I should be nervous of? Thanks \\n </s>
