DO NOT ATTACH THE REGULATOR/FLOWMETER IF CYLINDER VALVE IS DAMAGED! Inform your gas supplier of this condition.

3.Stand to one side away from the outlet and open the cylinder valve for an instant. This blows away any dust or dirt which may have accumulated in the valve outlet.

WARNING

Be sure to keep your face away from the valve outlet when “cracking” the valve.

4.Inspect the regulator/flowmeter for damaged threads and seals, dirt and dust. Remove dust and dirt with a clean cloth.

DO NOT USE THE REGULATOR/FLOWMETER IF DAMAGE IS PRESENT! Have an authorised repair station repair any damage.

WARNING

Gas under pressure is explosive. Always keep gas cylinders in an upright position and always keep chained to undercarriage or stationary support. Refer “Safety in Welding and Cutting” - ANSI Standard Z49-1 and WTIA Technical Note 7 available from the Welding Technology Institute of Australia.

5.Attach the regulator/flowmeter to the cylinder valve and tighten the union nut(s) securely with a spanner.

6.Attach the inlet gas hose to the outlet fitting of the regulator/flowmeter, and tighten the union nut securely with a spanner.

WARNING

Never stand directly in front of or behind the regulator/flowmeter when opening the cylinder valve. Always stand to one side.

7.Before opening the cylinder valve, turn the regulator adjusting knob counter-clockwise until the adjusting spring pressure is released.

8.Open the cylinder valve slowly a fraction of a turn. When the cylinder pressure gauge pointer stops moving, open the valve fully.

9.The regulator/flowmeter is adjustable. Set it for the flow rate recommended for the procedure and process being used before starting to weld.

Gun and Cable

The Magnum FM400 gun and cable provided with the machine is set up for 0.9/1.2mm operation.

1.Lay the cable out straight.

WARNING

Turn the welder power switch off before installing gun and cable.

2.Make sure all pins on the gun cable connector are aligned with the proper mating sockets on the front panel gun connector and then join the connectors and tighten the hand nut on the gun cable connector.

NOTE: If a gun and cable other than the Magnum FM400 gun are to be used, they must conform to standard European-style connector specifications. See diagram under.

The gun trigger switch must be capable of switching 10 milliamps at 60 volts DC—resistive.

CAUTION

The gun trigger switch connected to the gun trigger control cable must be a normally open, momentary switch. The terminals of the switch must be insulated from the welding circuit. Improper operation of, or damage to, the machine might result if this switch is common to an electrical circuit other than the machine trigger circuit.

Output Polarity Connection

WARNING

Turn the welder power switch off before changing output connection.

Connect the lead from the wire feeder to the output stud of the desired polarity.

Connect the work lead to the other output stud.
