DESCRIPTION

INSTALLATION (For help see fig. 1)

Figure 1

Connect the AEC 200-4D Direct Connect Spool Gun as follows:

1. Weld cable to the POSITIVE (+) terminal of the welding power source.
2. Control cable to the remote receptacle on the front of the welding power source.
3. Gas hose to the flowmeter/regulator at the gas supply.

DISCONNECT ALL ELECTRICAL POWER TO

THE WELDING POWER SOURCE BEFORE

INSTALLING THIS EQUIPMENT

WARNING!

PREWELD CHECK LIST

1. Make sure the AEC 200-4D Spool Gun is set up for wire size selected by having the proper liner, contact tube and nozzle.
2. Weld cable and hose is connected and tight. Control cable connection is fully inserted with the collar screwed on properly.
3. Mig wire is installed in a manner to allow the wire to feed from the top of the spool into the wire drive.
4. Proper shielding gas has been selected and the gas cylinder valve is on and backseated. Flowmeter properly set and hose line purged.
5. Power source on and correct voltage set.
6. Wire speed adjustment on Spool Gun is properly set.
7. Mig wire is through tip and extending just past end of nozzle.

NOTE: It is recommended to perform trial welds on scrap metal similar to what is going to be welded for adjusting proper wire speed, amps
and voltage settings. This will also familiarize you with the spool gun’s operating characteristics.

SHUTTING DOWN

After your welding job is complete or work is stopped for any appreciable amount of time proceed as follows:
1. Turn power source off.
2. Turn shielding gas off at the cylinder valve.
3. Make sure cover is secured onto spool gun.

MAINTENANCE

NOTE: Before performing any maintenance on this spool gun, BE SURE all sources of power have been TURNED OFF.
Check the following on a daily basis:
1. Inspect cables and hoses for frayed wiring or cracked insulation. Damaged wires and cable are hazardous and must be replaced.
2. Clean any spatter, grease or grime from the interior and/or exterior of the spool gun to prevent short circuits.
3. Check all mounting screws for tightness.
4. Keep cover on at all times to minimize dirt and contaminants from entering spool gun.
