When should a weld monitor be set up to sample weld data during resistance welding?

Most modern controls have current feedback and monitoring capability built in. They read and report each half cycle or millisecond depending upon the system being used. Older equipment may not have these features. The use of a monitor offers data confirmation, storage capacity, off-loading capability and security.

DeskTop Current Monitors with more features are readily available.

 Analysis of the entire weld cycle can be performed with the data available from today's controls and monitors. Controls or monitors can be turned on all the time to monitor each and every weld cycle. The data that is generated and what to do with it is another discussion.

Discussion of when and how to monitor this data is beyond the scope of the blog.
