PRODUCT DESCRIPTION

The CV320-I is a semi-automatic Constant Voltage DC arc welding power source and wire feeder. It combines a step controlled power source with a separate solid state controlled wire feeder.

Excellent arc characteristics are provided for both gas shielded and self shielded welding within its current range.

For instructions on operation of the wire feeder refer to the separate instruction manual included. Standard features include output volt & amp meters, a spot timer, gas purge facilities, a dual position 2 or 4 step trigger interlock, a Magnum FM400 gun, a regulator/flowmeter and gas hose, a 10m electrode cable and wire feeder cable, a 3m ground cable assembly, a 3m long input lead and an undercarriage on which a gas cylinder can be mounted.

INSTALLATION

Location

Place the welder where clean cooling air can freely circulate in through the intake louvers and out through the exhaust louvers. Dirt, dust or any foreign material that can be drawn into the welder should be kept at a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance thermostat trips.

Wire Feeder Mounting

Locate the control cable at the rear of the CV320-I and plug into the wire feeder. The control cable is already connected to the CV320-I. Connect the supplied 1.5m electrode cable to the wire feeder mechconnector and to the desired polarity terminal on the front of the CV320-I.

Connection to Mains Supply

Before connecting the machine to the mains supply check that the voltage and current capacity correspond to the machine voltage and rated input current. Use a fuse or C/B per AS3000 or local wiring rules.

The machine is supplied with an input lead fitted. Have a qualified electrician fit a suitable input plug.

CAUTION

Never connect the green/yellow conductor to any of the three active supply lines from the mains. This conductor is to earth the machine as required by Electrical Regulations.

Once the above has been followed the machine can be plugged into the mains outlet.

Shielding Gas Supply

(For the Gas Metal Arc Welding Process)

WARNING

HIGH

VOLTAGE

can kill

Turn the input power off at the disconnect switch before installing or servicing this machine.

Do not touch electrically “hot” parts such as output terminals or internal wiring.

Connect grounding screw ( ) to a good earth ground.

Do not operate with covers removed.

Turn power switch “off” before connecting or disconnecting cables or other equipment.

Refer “Safety in Welding and Cutting” - ANSI Standard Z49.1 and WTIA Technical Note 7, available from the Welding Technology Institute of Australia.

Obtain cylinder of appropriate type shielding gas for the process being used.

1.Set gas cylinder on rear platform of the machine. Hook chain in place to secure cylinder to rear of welder.

CYLINDER may explode if damaged

Only qualified personnel should install or service this equipment.

2.Remove the cylinder cap. Inspect the cylinder valve for damaged threads, dirt and dust. For cylinders having an external thread fitting, remove any dust and dirt from the threads with a clean cloth.
