How To Choose The Wire Liner For Direct And Euro Connection Torches; Arrangement For Welding With Spool Gun - Forney 242 MIG Manuel D'utilisation

In case you are replacing a Teflon or graphite wire liner, follow these instructions:
• Install the new liner and insert the wire liner collet (3) and the O ring (4).
• Mount the brass nut (1).
• Cut the wire liner close to the brass nut.
WARNING: THE LENGTH OF THE NEW WIRE LINER MUST BE THE SAME AS THE
LINER YOU HAVE JUST PULLED OUT OF THE HOSE.
• Connect the torch to the machine and install the wire into the feeding system.

How to Choose the Wire Liner for Direct and Euro Connection Torches

• There are basically 2 types of wire liners: Steel wire liners and Teflon wire liners.
• Steel wire liners can be coated or not coated. Coated wire liners are used for air cooled
torches.
• Teflon wire liners are recommended for aluminum welding as they allow a smooth feeding of
the wire.

Arrangement for Welding with Spool Gun

WARNING: ELECTRIC SHOCK CAN KILL! ALWAYS TURN THE POWER SWITCH
OFF AND UNPLUG THE POWER CORD FROM THE AC POWER SOURCE BEFORE
INSTALLING WIRE.
Before installing any welding wire into the unit,
the proper sized groove must be placed into
position on the wire drive mechanism. Adjust the
drive roller according to the following steps:
1. Open the wire drive cover on the spool
gun.
2. Remove the drive tension by loosening
the tension adjusting screw and lifting the
drive tension adjustor up, away from the
drive tension arm. Pull the drive tension arm away from the drive roller.
3. Rotate the drive roller cap counterclockwise and remove it from the drive wire drive cover
drive roller cap FIG. 7 tension adjusting screw drive tension arm roller. Pull the drive roller off
of the drive roller shaft . Note: The drive roller has two wire size (.030", .035") grooves built
into it.
4. Find the side of the drive roller that is stamped with the same wire diameter as that of the
wire being installed. Push the drive roller onto the drive roller shaft, with the side stamped
with the desired wire diameter facing you.
5. Reinstall the drive roller cap and lock in place by turning it clockwise.
6. Remove the nozzle and contact tip from the end of the gun assembly.
7. Open the wire spool casing, located at the rear of the spool gun, by turning the retaining
knob counterclockwise.
8. Unwrap the spool of wire and find the end of the wire.
9. After checking to make sure your welder is disconnected from the AC power source, free the
leading end of the wire from the spool, but do not let go of it until told to do so, or the wire
will unspool itself.
10. Using a wire cutter, cut off the bent portion at the end of the wire so that you are left with a
straight section of wire.
11. Unroll about 6" of welding wire from the wire spool.
12. Insert the leading end of the wire into the inlet guide tube (located in the Wire Spool Casing).
Then push it across the drive roller and into the gun assembly about 6".
