3 INTRODUCTION
LKA 180/240 is a compact, step−switched Welding power sources, intended for
welding with solid wire with shielding gas and tube electrode without gas.
The complete package comprises a power source with integral wire feed unit,
(PSF 160 welding torch), mains lead, return cable with clamp, feed rollers for 0.6
and 0.8 mm wire and a gas hose. The assembly kit includes a handle, rear axle, 2
rear wheels and 2 castors.
Two control knobs provide adjustment of voltage and wire feed speed, which are
easily selected by referring to the table on page 9.
You can switch between solid wire with shielding gas and tube electrode without gas
by simply switching + and − connections on the terminal above the wire feed unit.
The spot welding function simplifies the task of making lap joints in sheet metal. A
thermal cut−out prevents the power source from overheating. The cut−out is reset
atomatically when the power source has cooled.
