For use with the AEC-200 Welding Gun and related controls, however, it may also be used in any application requiring a welding contactor, as long as
operating parameters are observed.
PREWELD CHECK LIST
A.) Make sure the AEC 200 Welding Gun is set up for wire size selected with, proper liner, contact tube and nozzle.
B.) All control cable and hose connections are tight.
C.) Mig wire installed counter clockwise feed-off.
D.) Proper shielding gas and flow selected and cylinder turned on.
E.) Power source on and set for required amperage (or voltage).
F.) Proper control box selected and properly installed.
G.) Welding wire extended from end of nozzle.
H.) Cover secured on gun.
We recommend using scrap metal for trial welds and adjusting gun speed, amps and voltage before your welding
operation. This will familiarize you with the guns operative characteristics.
SHUTTING DOWN
After your welding job is complete or work is stopped for any appreciable time proceed as follows:
A.) Turn power source off.
B.) Disconnect 115 V AC on control box if separate from power source.
C.) Turn shielding gas off.
D.) Make sure cover is secured on gun.
MAINTENANCE
*NOTE: Before performing any repairs or maintenance on Gun, BE SURE all sources of Power are TURNED OFF.
It is important to periodically inspect and clean if necessar y the AEC 200 Welding Gun. Inspect the Gun as follows:
1.) Inspect cable/hose assembly, (power cords, control cables, gas hose) for frayed or cracked insulation.
Damaged wires and cables are hazardous to your health and should be repaired or replaced immediately.
2.) Look for and clean if necessary any grease or grime. Grease containing metallic par ticles can cause a short circuit.
3.) Check all mounting screws and nuts and make sure they are tight.
4.) Front cover should be in place during any welding operation. This keeps splatter from causing any short circuits.
