3 INTRODUCTION
The Professional 250 are one transistor controlled welding power source designed
for welding with coated electrodes and for TIG welding (touch start).
The advanced electronics provide rapid control response, low power demand and
excellent welding characteristics. Inverter technology contributes to low weight and
compact dimensions of the units.
The rounded slimline shape of the unit makes it comfortable to carry. The strap can
be folded to serve as a carrying handle, or fully extended to serve as a shoulder
strap.
