“Exceeding Customer Expectations Through Performance Excellence"

Valued Thermadyne Customer,

In 2006 Thermal Arc released the complete next generation ArcMaster portable Inverter line.

Many of these units (200 amps and above) have multi-voltage capabilities 208-230VAC Single phase

and 208-230VAC / 460VAC Three phase.

It has come to our attention that some customers are using an input voltage of 460VAC Single phase.

This is not a recommended input voltage for the ArcMaster line. Use on this voltage could cause

premature product failure and the voiding of warranty.

Please refer to the Specification page of the ArcMaster Technical Sales literature or the product

Operating Manual for the correct input voltage requirements.
