Welds on an inner edge

The preparation for this weld joint is very simple and is carried out for thick-
nesses of 5 mm. The dimension "d" needs to be reduced to a minimum
and should always be less than 2 mm.

For thicker materials, however, it is no longer expedient. In this case, it is better
to prepare a joint as shown opposite in which the edge of a plate is angled.

Overlap welds

The most usual preparation is that with straight weld edges. The weld can
be undone using a standard angle weld seam. Both workpieces must be
brought as close to each other as possible.

Cleaning and care

WARNING!
► To avoid the danger of electric shock, injury or damage:
–
Before cleaning, always disconnect the mains plug
from the mains power socket.
– Never immerse the flux-core welder or the accessories
in water.
– Allow the flux-core welder and accessories to cool
down before cleaning them.
–
Never use abrasive, caustic or scratching cleaning
agents. These can damage the appliance.
■ Keep the flux-core welder clean. Welding equipment must be kept free
of dust to ensure adequate cooling. In especially dirty air, a monthly
cleaning using compressed air is necessary.
■ Protect the flux-core welder from metal dust.
■ Store the flux-core welder in a dry room, secured from access by un-
authorised persons or children.
■ Ensure that the welding lead, the torch and earth clamp are all in
perfect condition.
■ Cables and current-carrying parts of the flux-core welder with dam-
aged insulation are dangerous and can impair the proper functioning
of the appliance.
■ Repairs may only be carried out by authorised repair shops or similarly
qualified persons.
■ Always disconnect the appliance from the mains power supply before
all maintenance and repair work.

Wire feed

■ Regular cleaning of the wire feed drive and replacement of worn wire
feed rolls.
■ Blow out the steel core with compressed air.
■ Do not tighten the tension spring on the pressure roller too tightly. Ex-
cessive pressure lead to higher abrasion of the steel wire. The dust thus
created deposits in the guide spring and causes an uneven discharge
of the welding wire making it impossible to create an even weld.

Cable assembly

■ Protect the cable assembly from external damage.
■ Never pull it over sharp edges or other objects.
■ Never drive a vehicle over it.
■ Clean the cable assembly regularly.
■ The steel sleeve and torch nozzle are wearing parts.
■ The torch nozzle is exposed to heat radiation and friction from the wire
and must be checked and replaced regularly.
■ Weld splatter collects on the torch nozzle. This must be removed
regularly.
■ For overhead welding, frequent cleaning is necessary.
■ Use nozzle grease or nozzle spray before and after welding. This
prevents too much splatter from accumulating.

Welder

■ The transformer of the welder must be freed of accumulated dust to
ensure that the cooling works properly. In especially dirty air, a monthly
cleaning using compressed air is necessary.
■ Protect the welder from metal dust.
