MAINTENANCE
Wire fed unit Check the wire feed unit at regular intervals. The feed roller wire guide plays an
•
important part in obtaining consistent results. Poor wire feed affects welding. Clean the rollers weekly,
especially the feed roller groove, removing all dust deposits.
Torch Protect the torch cable assembly from mechanical wear. Clean the liner from the machine
•
forwards by using compressed air. If the liner is clogged it must be replaced.
Changing Feed Roler
•
Contact tip The contact tip is a consumable item and must be replaced when the hole becomes
•
enlarged or oval. The contact tip MUST be kept free from spatter to ensure an unimpeded flow of gas.
Gas Cup The gas cup must also be kept clean and free from spatter. Build up of spatter inside the gas
•
cup can cause a short circuit at the contact tip which will result in either the fuse blowing on the printed
circuit card, or expensive machine repairs. To keep the contact tip free from spatter, we recommend
the use of Solter anti-spatter spray available from your Solter Dealer. Refer to fig.12 and for removal
and replacement.
Replacing the Liner Wind the wire back on to the spool and secure it. Unscrew the torch from the
•
machine and undo the brass nut. The liner should now be visible. Pull it out and replace with a new
one.
