PRODUCT DESCRIPTION
The Multi-Weld 350 converter (K1735-1) is part of a
Multi-Weld system, ideally suited for construction site
welding, which uses a single DC power source, as the
only input supply, and provides independent full range
control of up to 350A continuous with each converter
arc for + polarity stick and wire processes, as well as
for arc-air gouging.(See Figure 1).

700 AMP ARC GOUGE
The Multi-Weld 350 is a DC to DC converter which
converts higher voltage/lower current input power to
lower voltage/higher current output power with over
90% efficiency.
For example; a single 600A continuous rated 70-80v
power source could supply up to five Multi-Weld 350
converters each wire welding at 300 amps, or about
ten converters for stick welding at 150 amps, with 26-
29v at the arcs.
The Arc Converter is a single "world" model built to
IEC and CSA standards and meeting the specific
needs inherent to construction site welding:
Versatile
• Constant Current (CC) mode for stick and gouging.
Includes Hot Start and Arc Force controls to opti-
mize CC performance, and can be paralleled for
higher capacity welding and arc gouging.
• Constant Voltage (CV) mode for positive polarity
cored and solid wire welding with arc-powered
feeders (such as the LN-25).
Portable
• Arcs can be moved quickly with the light weight
Converter thatʼs easy to carry, or pull, and is small
enough to fit through a 15" (38cm) diameter or 12"
x 16" (31x 41cm) elliptical man-hole.
• Converter is powered by the welding cable from
the DC power source, without the safety hazard of
high AC input supply voltages.
