a better feed is created, but over time the surface of the welding wire will slowly erode, which can lead
to blockages in the wire guide A U-groove roller for cored wire can also be used, thanks to which one
can avoid a blockage at the price of lower feed quality. Compared to solid wire, cored wire welding has
the advantage that you do not need any accessories for gas, you can also do work outside, but there
are also disadvantages because this method creates more spatter, the slag must be removed, and the
quality of the seams is poorer than with inert gas welding. Shielding gas is not used for cored wire.
Soft wire / aluminium wire - Aluminium welding is considered to be a more demanding welding
process because it has the disadvantage that the material is softer and can therefore easily deform
or bend and get caught when the wire is fed into MIG MAG welding machines. On the other hand, it has
the advantage, compared to steel, that it is a very light material, which is durable, weather-resistant and
has very high strength. In contrast to cored wire or solid wire, a wire feed roller with a U-shaped groove
is used for aluminium. Since aluminium is softer and easy to bend, the U-groove creates more grip and
stability, thanks to which the feeding of the soft wire is made easier without kinking or deforming. In
addition to the U-groove wire roll, a Teflon core with a brass spiral must also be used for aluminium; this
is built into the torch so that the wire is perfectly guided through the torch to the gas nozzle. The devices
are often equipped with a metal core, which is why you must replace this with a Teflon core when welding
aluminium. The best shielding gas for aluminium welding is argon.
Our welding machines are always tested and calibrated before shipment. Any unauthorized
modification of the device is prohibited and has a negative effect on the guarantee!
The modifications can only be caried out by the technicians of the sales company!
The operating instructions must be read carefully to ensure that there are no unintended complications
that could endanger the user.
Before starting any repairs, it is necessary to switch off the welding machine!
If there is a problem with the device and there is no authorized specialist in your place of residence, it
is best to contact the seller.

Solution
Replace micro fuse: 2.5 A (3.15
A)
Have the connection checked
by a specialist
Set the correct pressure (it must
be possible to block the wire roll
by hand)
Bring the feed roller and wire
guide into line
Check, possibly change
Replace the wire roll
Replace the wire roll, clean or
replace the guide spiral
Release mandrel brake, screw
on
Clean the feed roller
