Monthly Maintenance Tasks; Maintenance Work; Disposing Of Equipment - EWM MTR242W Operating Instructions Manual

6.2.2

Monthly maintenance tasks

• Check the coolant container for sludge deposits and check the coolant for cloudiness.
Clean the coolant container if contaminated, and change the coolant.
• If the coolant is dirty, rinse through the welding torch alternately several times with fresh coolant using
the coolant return and supply.
• Check the wire guide.
• Check and clean the welding torch. Deposits in the torch can cause short circuits and have a negative
impact on the welding result, ultimately causing damage to the torch.
• Check that all screw and plug connections and replaceable parts are secured correctly, tighten if nec-
essary.
After each maintenance, reconnect the welding torch, purge it with shielding gas using the "Gas
test" function and vent the cooling circuit > see 7.2 chapter.
When the torch neck is exchanged for a torch neck with a different length, the wire guide must
be adapted.
6.3

Maintenance work

Electric current!
Repairs may only be carried out by authorised specialist staff!
• Do not remove the torch from the hose package!
• Never clamp the torch body in a vice or similar, as this can cause the torch to be irreparably
destroyed!
• If damage occurs to the torch or to the hose package which cannot be corrected as part of
the maintenance work, the entire torch must be returned to the manufacturer
6.4

Disposing of equipment

Proper disposal!
The machine contains valuable raw materials, which should be recycled, and electronic compo-
nents, which must be disposed of.
• Do not dispose of in household waste!
• Observe the local regulations regarding disposal!
• According to European provisions (Directive 2012/19/EU on Waste of Electrical and Electronic Equip-
ment), used electric and electronic equipment may no longer be placed in unsorted municipal waste. It
must be collected separately. The symbol depicting a waste container on wheels indicates that the
equipment must be collected separately.
This machine has to be disposed of, or recycled, in accordance with the waste separation systems in
use.
According to German law (law governing the distribution, taking back and environmentally correct dis-
posal of electrical and electronic equipment (ElektroG)), used machines are to be placed in a collection
system separate from unsorted municipal waste. The public waste management utilities (communities)
have created collection points at which used equipment from private households can be disposed of free
of charge.
The deletion of personal data is the responsibility of the end user.
Lamps, batteries or accumulators must be removed and disposed of separately before disposing of the
device. The type of battery or accumulator and its composition is marked on the top (type CR2032 or
SR44). The following EWM products may contain batteries or accumulators:
• Welding helmets
Batteries or accumulators are easy to remove from the LED cassette.
• Device controls
Batteries or accumulators are located on the back of these in corresponding sockets on the circuit
board and are easy to remove. The controls can be removed using standard tools.
Information on returning used equipment or collections can be obtained from the respective municipal
administration office. Devices can also be returned to EWM sales partners across Europe.
