Page 3: Electric Shock Can Kill
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. - Page 4 WELDING and CUTTING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding materials from welding can easily go through small cracks and openings to adjacent areas.

Page 10: Safety Precautions
Dirt, dust, or any foreign material that can be drawn into the welder should be kept at a mini- mum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdowns. -

Page 13: Recommended Electrode And Work Cable For Arc Welding
RECOMMENDED ELECTRODE AND WORK CABLE SIZES FOR ARC WELDING General Guidelines Connect the electrode and work cables between the appropriate output studs of the FLEXTEC™ 450 CE per the following guidelines: • Most welding applications run with the electrode being positive (+). For those applications, connect the electrode cable between the wire drive feed plate and the positive (+) output stud on the power source. - Page 14 SAFETY PRECAUTIONS Read this entire section of operating instructions before operating the machine. WARNING ELECTRIC SHOCK can kill. • Unless using cold feed feature, when feeding with gun trigger, the electrode and drive mechanism are always electrically energized and could remain energized several seconds after the welding ceases.
-
Page 15: Operation
• Simple user interface - designed with the operator in mind. Getting setup for the weld is several clicks away and even the most novice welder can be confi- dent he is setup properly. • F.A.N. (fan as needed). Cooling fan runs when the output is energized and for a 5 minute cool down period after output is disabled. -
Page 16: Recommended Processes And Equipment
RECOMMENDED PROCESSES AND EQUIPMENT RECOMMENDED PROCESSES The Flextec™ 450 CE is designed for CC-MMAW, CC-GTAW (lift tig), CV-GMAW, CV-FCAW-SS and CV-FCAW-GS welding processes. CC- CAG (arc gouging) is also supported in the MMAW mode. PROCESS LIMITATIONS The Flextec™ 450 CE is suitable only for the processes listed. -

Page 18: Power-Up Sequence
The serviceability of a product or structure utiliz- ing the welding programs is and must be the sole responsibility of the builder/user. Many variables beyond the control of The Lincoln Electric Company affect the results obtained in applying these programs. These variables include, but are... - Page 19 Amperage Display Meter • Prior to STICK or TIG operation (current flow), the meter displays preset current value. • Prior to CV operation, the meter displays four dash- es indicating non-presettable AMPS. • During welding, this meter displays actual average amps.
- Page 20 BASIC MODES OF OPERATION MMAW This weld mode is a constant current (CC) mode fea- turing continuous control from 15 – 500 amps. It is intended for the MMAW stick welding processes and arc gouging. Hot Start - The Hot Start control regulates the starting current at arc initiation.
- Page 21 The remote potentiometer controls the amperage from minimum to this pre-set maximum. CV-GAS This weld mode is a constant voltage (CV) mode featuring con- tinuous control from 10 to 45 volts. It is intended for the GMAW, FCAW-GS, MCAW welding processes.
