MAINTENANCE

9.1

Routine

Keep all instructions and fi gures on the welding machine clear and legible.
The mains cable and welding cables must be insulated and in perfect condition; be careful with the tips, which fl ex: near
the connection terminals, earth clamps and gun input.
Keep the welding current connectors to sockets B and C clean and fi rmly tightened (see Fig. 1)
The terminals for connecting to the base metal must make good contact to avoid overheating, sparks, uneven current
circulation, damage to the components where the pins are welded, and welding of uneven quality.
Prevent dirt, dust and fi lings from getting into the welding machine.
Always make sure the cooling air circulates freely.
Make sure that the fan functions properly.
Make sure that the clamps hold the stud bolts fi rmly, with all contact springs.
The clamp must slide freely throughout its length, without changes due to friction or foreign matter.
9.2

Special

Only qualifi ed personnel should perform maintenance.
Some functional errors are highlighted by the appearance of an error code on the display A.
Wait at least 5 minutes after shutting off the switch E before opening the welding machine, and unplug the plug from
the power socket.
Use a volt meter to make sure that the capacitors are discharged.
Carefully remove any dust, metal fragments and fi lings from the machine using compressed air to avoid damaging or
projecting metal fragments onto the electronic or electrical parts.
Make sure that all connectors are fully inserted.
Make sure that all welding circuit terminals are fi rmly tightened.
After making a repair, make sure to rearrange the wiring so that there is secure insulation between the primary
and secondary sides of the machine. Do not allow wires to come into contact with moving parts or those that heat
up during operation. Reassemble all of the clamps as they were on the original machine, to prevent an accidental
connection between the primary and secondary circuits if a conductor should break or disconnect.
Also remount the screws with geared washers as on the original equipment.
