CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the correct
shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.
MOVING PARTS ARE DANGEROUS: There are moving mechanical parts in this machine, which can
cause serious injury. Keep your hands, body and clothing away from those parts during machine
starting, operating and servicing.
The manufacturer reserves the right to make changes and/or improvements in design without upgrade at the same time
the operator’s manual.
Installation

of the machine.
General Description
The Flextec 350x CE is an inverter based, multi-process,
DC power source that has a 5 to 425 Amp output range.
The machine is capable of welding in CC and CV modes
with common wire types and sizes. The Flextec 350x CE
is capable of gouging in either Stick or CV modes. Two
units can be paralleled in CC modes for extra gouging
power.
The Standard and Construction include GMAW, FCAW,
SMAW, and GTAW for a variety of materials including
mild steel, some cored wires, gas shielded wires, and
aluminum wires. Additional modes are offered
supporting reduced open circuit voltages for an added
measure of safety. The Flextec 350x CE Standard
machine includes an ArcLink mode setting that allows
the power source to weld synergic modes.
The Flextec 350x CE Standard is designed to be
compatible with the current range of semi-automatic
ArcLink wire feeders in addition to the analog and
across-the-arc wire feeders. The Flextec 350x CE
Standard comes with a 5-pin ArcLink digital feeder
connector, a 12-pin remote outuput connector, and a
14-pin alalog feeder connector standard. Voltage
sensing is either done at the studs or via a 67 lead when
operating with an ArcLink wire feeder.
The Flextec 350x CE Construction machine only comes
with a 12-pin remote output connector and is only
compatible with across the arc wire feeders and
CrossLink™ compatible feeders.
All of the models of Flextec 350x CE come with the
CrossLinc™ interface for remote voltage setting with
CrossLinc™ compatible feeders or remote controls.
Recommended Processes
Flextec 350x CE is designed for CC-SMAW, CC-GTAW
(Touch Start TIG™), CV- GMAW, CV-FCAW-SS, CV-
FCAW-G. CAG arc gouging is also supported in the CV
and CC modes.

Product Specific Installation
Limitations
CrossLinc™ technology uses a communication protocol
coupled on the electrode and work cables. For best
performance the total voltage drop in the system should
be kept under 10V.
CrossLinc™ is not compatible with High Frequency TIG.
If HF is in the area, the cables need to routed as far as
possible from each other. Also follow all high frequency
best practices, including the driven earth ground.
