Abstract
A welding monitor for use with a welding system is described. The monitor comprises a store (74) for storing at least two sets of predetermined acceptable ranges for one or more welding parameters such as voltage and current. A comparator bank (66,67) is provided for each parameter to compare the operating value of each parameter in use with the corresponding stored range or ranges. A display including sets of light emitting diodes (18-20) displays information relating to the stored ranges and operating values and is responsive to the comparator banks (66,67) to indicate the relationship between an operating value of at least one of the parameters and the corresponding predetermined range.
