Section 3 - Setting Up For Welding - Lincoln Electric REDI-MIG 4S Operator's Manual

Section 3 - SETTING UP FOR WELDING

The following items are required:
1. REDI-MIG Remote or other suitable constant voltage power
®
source.
2. A reel of wire of suitable size and type.
3. A control/power cable assembly to connect the wire feeder to
the power source.
4. A suitable gun and cable assembly with a "Euro" connector
and the correct contact tip and, if necessary, gas nozzle for
the consumable being used. See "Connections" on Page 8
for details of recommended Linc guns for use with REDI-MIG
Remote power sources.
5. Correct drive rolls for the wire size and type to be used. The
wire feeder is supplied with a 0.9/1.2mm solid wire feed roll as
standard; drive rolls for other types and sizes are available as
spare parts.
6. A work return cable and clamp.
7. Normal welding accessories including helmet or hand shield
with suitable lens, gloves etc.
8. If a gas shielded process is to be used; appropriate gas
cylinder, regulator/flowmeter and hose.
Connect the control and welding cables to the welding power
source.
If gas shielding is required, connect the gas hose.
Remember that gas cylinders may explode if damaged, so ensure
that all gas cylinders are securely mounted.

Fit a spool of appropriate wire onto the spool so that it turns
clockwise as the wire is fed.
Carefully release the end of the wire from the spool ensuring that
the released end is held to stop the wire from unravelling. Cut off
the end kink to give a smooth straight end of wire.
Obtain a gap between the wire feed roll and the pressure roll
by lifting the cam latch. Feed the wire end into the guide tube,
between the drive rolls, and into the "Euro" connector guide until it
protrudes about 20mm out of the front of the "Euro" connector.
Close the drive rolls by lowering the cam latch ensuring the
®
rolls firmly hold the wire. Adjust the tension so that wire feeds
smoothly. Do not over tighten.
Fit the gun and cable assembly onto the "Euro" connector by
slipping the end of wire into the cable wire hole.
Tighten the "Euro" connector lock ring.
Activate the power source; set the wire feed speed to 4 on the dial
and press the gun trigger or wire inch push button (if fitted). The
wire feed roll should turn, feeding the wire further up the gun and
cable assembly. Ensure there are no kinks or sharp bends in the
gun cable and hold the gun trigger or wire inch button until the
wire emerges from the gun. It is good practice to remove the tip
when first feeding a new coil of wire, then refitting over the wire
and tightening. Cut off the end of the wire leaving 10mm to 15mm
stick-out. Select required polarity. See Section 1
