“Exceeding Customer Expectations Through Performance Excellence"

Valued Thermadyne Service Provider

For customers with generators or fluctuating power issues “Specifically with High pick of voltages

” (65 input power

flashing error code) a new firmware was released to widen the Hi range of working input power.

The release was done in December 2008 as version 3.0 (third led from left and bottom led 0).

Units with version 2.7 (second led from left and end top led 7) and below will need to be updated in case the unit

experiences issues on the hi-end of the voltage specs.

NOTES.

1. The Logic board with the 3.0 version does NOT address issues with low lines ( 208v -10%) or low KVA’s from

the input voltage supply or mains.

2. There was no version 2.8 or 2.9 (no vertical lad's to display that rev as they are numbered 0 - 7).
