0-51 Error

[Rickzink]

Hi all.....I'm hoping to get a little help here. I bought this table from a neighbor who was retiring and it has been a long road to say the least. Admittedly, I am new to this world so I am sure part of my frustrations are coming from inexperience however, this damn table has one problem after another and I am ready to crush it with my excavator. I have had this thing over a year now and have literally spent 80% of my time troubleshooting endless issues. Needless to say, I am developing a love/hate relationship with this thing.

Ok...Now that I have vented my frustrations, here is one of my current problems.

For some reason I cannot seem to identify, this plasma cutter is giving a error code on 0-51. It has recently started doing this. Generally, it seems to really want to do it right before whatever I am cutting is finished. I mean it is on its last cut and then it does it. It does seem to do so after it has been running for a little while. I unplug it or let it sit for awhile, sometimes overnight, and i come in power it on and it runs fine for awhile.

Its a Hypertherm Powermax 65.

Please HELP!!! So I can move on to my next frustrating problem which I am sure will surface immediately after this issue is addressed....at least that has been the history of this so far.

Thanks in advance.

as a “stuck start.”

Sound like your torch fire relay is stuck (machine torch)

Are you using a machine torch or hand held style torch on this table?
