of arc welding machines.
9. DUTY CYCLE
When the machine reaches the end of its duty cycle and overheats, the thermostatic switch opens to allow the internal components
to cool. This is denoted by the error page illuminating. Allow the machine to cool and resume use when the error warning clears.
10. MAINTENANCE
10.1.
WIRE FEED 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.
10.2.
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.
10.3.
CHANGING FEED ROLLER (See Section 4.6.)
11.4.
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. Refer to fig.9 and section 4.4.4 for removal and replacement.
10.5.
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 Sealey anti-spatter spray (MIG/722308) available from your
Sealey Dealer.
10.6.
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.
10.7
Remove the casing periodically and, with a low pressure air flow (max 1bar or 15psi), remove dust from inside the machine.
10.8.
Do not direct compressed air onto the electronic circuit boards, these should be cleaned with a very soft brush.
10.9.
Ensure that all electrical connections are tight and check the wiring for damage to the insulation.
10.10.
Ensure that the casing is correctly replaced and secured before attempting to use the inverter.
10.11.
Keep the outside of the machine clean by wiping with a soft, dry cloth.
For any other service or maintenance, contact your local Sealey service agent.
