IBRUGTAGNING
Nettilslutning
Kontroller at maskinens påstemplede spænding er i overenstemmelse med netspændingen. Hvis maskinen er
omkobbelbar, skal det kontrolleres, at maskinen er koblet korrekt.
Tilslutning af gasflaske
Maskinen er beregnet for anvendelse af gasflasker med en max. højde på 100 cm. Ved anvendelse af større
flasker er der risiko for, at maskinen vælter.
Konfigurering
Hvis maskinen udstyres med svejsebrænder og svejsekabler, der er underdimensioneret i forhold til svejse-
maskinens specifikationer f.eks. med hensyn til den tilladelige belastning, påtager MIGATRONIC sig intet an-
svar for beskadigelse af kabler, slanger og eventuelle følgeskader.

VEDLIGEHOLDELSE
Manglende vedligeholdelse kan medføre nedsat
driftssikkerhed og bortfald af garanti.
Trådfremføringsaggregatet
Trådfremføringsaggregatet må regelmæssigt efterses
ved trådtrissen og tråddyserne. Dyserne i fremfø-
ringsaggregatet skal udskiftes, hvis tråden ved pas-
sage gennem dyserne deformeres eller får ødelagt
kobberbelægningen. Undertiden ses det, at afskrabet
kobberstøv totalt forhindrer en fri passage gennem
trådlederen. Kontroller dysernes justering, og rengør
disse efter behov. Desuden efterses og rengøres ril-
lerne i trådtrissen.
Slangen
Slange skal beskyttes mod overlast og må ikke træ-
des på eller køres over. Slangen bør afmonteres og
trådlederen blæses ren med trykluft efter behov.
Svejsepistolen
Svejsepistolen indeholder vigtige komponenter, som
hyppigt må efterses og rengøres, nemlig kontaktdy-
sen og gasdysen. Sprøjtestænk må jævnligt fjernes
samtidig med, at der påføres MIG SPRAY. Under
rensningen bør gasdysen aftages.
Rens ikke ved at slå på pistolen.
Strømkilde
Strømkilde, ensretter og transformator skal med pas-
sende mellemrum blæses rene for støv.
Vigtigt:
Når der skal åbnes til strømkilden, skal netspændin-
gen til svejsemaskinen afbrydes. Dette gælder også
ved udskiftning af elektronikboks.
FEJLSØGNING
For lille svejseeffekt, svejsningen ligger som en
"larve" på emnet.
1. Den ene af de tre sikringer ved hovedafbryderen
er sprunget (gælder kun 3-fasede maskiner).
2. Der svejses på et for lavt spændingstrin.
Stødvis trådfremføring.
1. Indgangsdysen og trådtrissens rille flugter ikke.
2. Rulle med svejsetråd går for stramt på akslen.
Undertiden er tråden spolet forkert, så den "kryd-
ser".
3. Indgangsdyse eller kontaktdyse er slidt eller
snavset, evt. tilstoppet.
4. Svejsetråden er uren eller af dårlig kvalitet, evt.
rusten.
5. For dårligt tryk på modrullen.
For meget sprøjt ved svejsningen.
1. For stor trådhastighed i forhold til svejsningen.
2. Slidt kontaktdyse.
Svejsningen bliver kokset og "sprød".
Ved punktsvejsning fremkommer en karakteri-
stisk top.
1. Beskyttelsesgas mangler: for lavt tryk, eller flas-
ken er tom.
2. Gasdyse tilstoppet.
3. Utætheder i systemet, således at atmosfærisk luft
pga. injectorvirkningen suges med ind og blandes
med beskyttelsesgassen.
Tråden brænder gentagne gange fast i kontakt-
dysen og går trægt.
1. Kan bero på, at tråden er blevet deformeret i tråd-
lederen.
Klip tråden ved trådtrissen, og træk den deforme-
rede tråd ud af trådlederen. Sæt ny tråd i og kon-
troller modrullens tryk.
2. Slidt kontaktdyse.

INITIAL OPERATING
Mains connection
It is important to ensure that the mains supply voltage is in accordance with the voltage to which the machine is
built. If the machine can be adjusted for use on several different voltages then the machine must be checked to
confirm that it has been set to the correct voltage.
Connection of gas bottle
Use only gas bottles with a max. height of 100 cm. If larger bottles are used the machine may tip over.
Configuration
MIGATRONIC disclaims all responsibility for damaged cables and other damages related to welding with
under sized welding torch and welding cables measured by welding specifications e.g. in relation to per-
missible load.

MAINTENANCE
Insufficient maintenance may result in reduced
operational reliability and in lapse of guarantee.
Wire feed unit
This unit must be kept clean with dry, clean, com-
pressed air and maintained regularly in the areas of
the wire drive rolls and capillary tubes, as it is
essential for consistent wire feed, satisfactory weld-
ing results, and a minimum of wear and tear, that
the wire passes through the wire drive system with-
out any deformation of the wire or the wire drive
rolls.
The contact tips must be checked often and
changed if the copper plating of the wire is damaged
on its way through the tips.
Copper dust may prevent free passage of wire
through the torch liner. Check and cleaning of the
capillary tubes and the wire drive rolls is recom-
mended when necessary.
Welding hose
Great care should be taken to ensure that the
welding hose is not overloaded. It should not be
pulled over sharp edges, and heavy machines
should not run over it as this may damage the torch
liner.
The torch hose assembly should be dismantled
when necessary and blown out with clean, dry com-
pressed air. The torch must be disconnected from
the machine during this process.
Welding torch
There are many parts in the welding torch that have
to be cleaned regularly. The main ones are the
contact tips and the gas shroud.
During the welding process, these parts are bom-
barded with spatter that sticks to the shroud. This
may disturb the shielding gas flowing from the gas
shroud down to the molten pool, and must be
removed regularly. The use of MIGATRONIC MIG
SPRAY loosens spatter.
During the cleaning process, the gas shroud should
be removed. Do not clean by banging or hitting the
torch.
Power source
The rectifier and transformer should be blown out
with dry air occasionally, otherwise the air circu-
lation will be affected by the dust.
Important!
Make sure that the machine is disconnected from
the mains supply when the power source needs to
be opened for e.g. replacement of control unit.
TROUBLE SHOOTING
Too little welding effect.
The welding seam forms a bead standing proud
of the plate.
1. One of the three fuses in the main switch is not
working. (This applies to three-phase machines
only).
2. The welding voltage is too low.
Switch one setting higher.
The wire feed is blocking.
1. The inlet nozzle and the wire are not in align-
ment with each other.
2. The reel of wire is too taut, the wire must come
off the reel evenly.
3. The inlet or contact tip has worn out or is
blocked up.
4. The welding wire is not clean or it is rusty. It
could also be of an inferior quality.
5. The pressure roller has to be tightened.
Spatter.
1. The wire feed is too fast for the voltage setting.
2. Worn out contact tip.
Porous weld. A cone is formed when spot wel-
ding.
1. Insufficient gas - too little pressure or the bottle
is empty.
2. Contact tip is blocked up.
3. Leakage air is pumped in and mixes with the
shielding gas.
The wire keeps sticking in the contact tip and
feeds at slow speed.
1. The damaged wire should be cut off, pulled out
and replaced. The pressure on the wire feed
roller should be checked and adjusted if neces-
sary.
2. Worn out contact tip.
3. Wire feed speed may need increasing.
