Description
These Maxus wire feed welders are
designed to be used on standard 120V
(MXW308 & MXW309) or 230V
(MXW413) outlet. The welder is
equipped with infinite wire speed
control to accurately select the proper
wire feed rate needed for various
welding conditions. Internal components
are thermostatically protected.
This welding system is designed for use
with the Flux Cored Arc Welding
(FCAW) or the Gas Metal Arc Welding
(GMAW) process. As delivered from the
factory, this welder can weld with .030"
(0.8mm) diameter flux core wire. A
starter spool of .030" (0.8 mm) flux
cored wire is included.

/hose kit must be purchased in addition
to the shielding gas and MIG wire.
