Description

Now updated to our Calibrator Pro 800 & 1000 models – Better performance in every way – take a look at the benefits below.

The easiest & fastest way to calibrate every type & make of welding machine. Just plug into your machines output terminals & get testing!

Guaranteed to work on every make & model of welding power source. 

Multiple load resistors are built into a tough aluminium enclosure, the resistive loads are selected using the front panel switches. Each of the main load switches can be operated independently & a 6 step fine switch gives more precise adjustment of load, the result is 100’s of different load values allowing testing of all MIG/MAG, TIG & MMA power sources (GMAW, FCAW, GTAW, SMAW) up to 800 or 1000A.

Calibrator Pro instrument panels use the most precise high stability electronics available & accuracy levels exceed the highest requirements of IEC60974-14. This allows calibration & testing to precision grade where needed. Suitable for the most demanding industries such as nuclear, aerospace, Government laboratories etc.

This wide range of load resistance allows testing on all welding processes in accordance with the volt/amp relationship formula. For instance on MIG/MAG at 500A you can achieve 39V, on TIG you can achieve 30V, on SUB ARC 40V etc. Every load setting is marked with the approx. current rating, but all will withstand high overloads as often happens during load testing of welding equipment. Load resistances start at 5Ω and with all loads switch on resistance is 0.043Ω for 800 model & 0.033Ω for 1000A model.

Calibrator Pro models utilise ‘stack effect’ cooling to pull in cold air at the bottom & force hot air out of the top this provides exceptional cooling for the load resistors allowing over 35kw (800 model) (50kw 1000 model) of peak load power.

Calibrator Pro 800 is fitted with 7 main loads + 6 position fine control – up to 900A peak amperage.

Calibrator Pro 1000 is fitted with 8 main loads + 6 position fine control – up to 1250A peak amperage.

Features & functions (with instrument panel fitted)
