Continued set up of the Spool Gun for RAZOR 165-200 MIG

(8) Carefully feed the wire through the red guide tube into meet the drive roller. Push down the tension

arm adjustment lever to release the drive roll pressure allowing the wire to be guided through the drive

rollers into the gun neck.

(9) Replace the spool cover

(10) Remove the gas nozzle and contact tip from the torch neck, Pull the trigger to drive the wire through

the neck until it exits the contact tip holder.

(11) Fit the correct sized contact tip by feeding the wire through it, screw the contact tip into the tip holder

of the torch neck and nip it up tightly.

(12) Check the drive roll pressure is enough to drive the wire smoothly and adjust the drive roll pressure if

required by using the adjusting screw at the top of the torch body. Do not apply too much pressure.

(13) Fit the gas nozzle to the torch head.

(14) Carefully open the gas cylinder valve and set the ow rate to between 8-12 l/min.

(15) Set the welding parameters using the wire feed and voltage control knobs.

(16) Using the Burn Back control set the amount of wire to ‘burn back’ after you release the torch

trigger. This prevents the wire becoming stuck in the weld pool when nishing the weld.

(8) Carefully feed the wire through the inlet

guide tube onto the drive roller through into

the outlet guide tube. Push down the tension

arm lever to release the pressure of the drive

roller allowing the wire to be guided through

the drive roller into the gun neck.

(9) Replace the Spool Cover.

(15) Set welding parameters using the

voltage and wire feed controls.

(16) Adjust the burn back control to prevent

the wire sticking in the weld pool.

Caution:

Disconnect the Electrode Holder cable from the machine before using MIG function. If cable is not disconnected welding

voltage is present and can cause arcing or ash.

(12) Adjust the drive roll pressure if required

by using the adjusting screw at the top of the

torch.

(13) Fit the gas nozzle ready for welding.(11) Fit the contact tip over the wire and

screw it into the tip holder, nip it up tight.

(10) Remove the gas nozzle and contact tip.

Pull the trigger to drive the wire through the

neck until it exits the contact tip holder

(14) Carefully open the valve of the gas

cylinder, set the ow to 8-12 l/min
