Fubag TSMIG 150 — welding Machine Maintenance & Safety: Overload Protection Guide [8/20]

Превью страниц Страница 8 / 20

Attention:

Warning!

If welding with large current for a long time and exceed the duty cycle, the overload lamp

will light. The machine will stop working until locking to the stated temperature. When the overload

lamp lights you must stop welding and wait about 15 minutes , you can continue.

If the equipment can not work normally, you should stop working at once and check

trouble reason. You must use career man to maintenance ; forbid repairing, you had better to use

commendatory spare parts.

Before any maintenance, make sure the main switch has been cut or remove the fuse.

9. Maintenance

Keep from the rain, snow and long term exposing to sunlight when welder is used outdoor.

The professional maintenance personnel should use dry compressed air (use air compressor or

bellows) to remove the dust inside the machine. The part adhering to grease must be cleaned with

cloth while make sure there are no loosing parts existed in the tightened places and connected

cable. Usually the machine should be cleaned once a year if the dust accumulation problem is not

very serious, while it needs cleaning once or even twice every quarter if the dust accumulation

problem is serious.

Regularly check the input & output cables of welder to guarantee them right and firmly connected

and avoid them being exposed. Check should be taken once every month when fixed using and

every check taken when removing.

Regularly check the seal performance of gas system, whether the fan and feeder motor having

abnormal sound and whether every joint being loose.

Keep torch cable direct when welding.

Regularly clean the splash of nozzle (cannot use the way similar to knocking the torch head) and

stick to using splash ointment. Don’t remove the feeder device by means of pulling he torch cable.

Use qualified wire, no using inferior or rusty wire.

Clean the dust of liner with compressed air after the welder using some time (the dust is

accumulated by friction between wire and liner roll if find it wear and tear to prevent wire uneven

feeding.

The pressed roll can not be pressed too firm to guarantee smooth wire feeding. (It will lead to wire

deformation, adding the feeding resistance and accelerating the friction of gear if pressed over

firmly.)

- The main loop voltage happens to be a bit higher, so safety precaution should be taken before

repair to avoid accidental shock. The untrained people are forbidden to open the case.

Power source needs to be cut off before dust removal

Never tamper with wire or damage the component parts when cleaning.
