Selection of filler metals for use with new
Rebel multi-process por table welder
ESAB is making it easier for customers to identify and
purchase filler metals that are compatible with its recently
launched Rebel multi-process welding machine. Customers
are reporting that the machine’s smart MIG welding function
gives a stable arc and the innovative user interface, with
its colour screen, makes set-ups easy. To help customers
maximise their productivity without compromising quality
ESAB has published a list of Rebel-compatible filler metals.
Four MIG wires (including two for stainless steel), two
flux-cored wires and three MMA welding electrodes (one for
stainless steel) are included on the list. In addition, customers
can use their own choice of filler metal when TIG welding with
the Rebel. A new web page has been added to the Rebel
section of the ESAB website so customers can see at a
glance which filler metals should be used with the Rebel. For
each filler metal a link is provided for access to more detailed
product information. A further user-friendly feature of the new
web page is that customers can click on a ‘where to buy’ button
to find the nearest distributor.
Rebel’s sMIG function produces a smooth arc so ESAB
recommends its smooth-feeding OK AristoRod 12.50 non-
copper-coated wire with advanced surface characteristics. In
addition to benefiting from exceptionally smooth feeding, this
wire also promotes longer torch life, reduces spatter, ensures
excellent arc ignition and emits low levels of fumes.
ESAB’s OK Autrod 12.51 is a copper-coated wire that
provides a more fluid puddle and smoother bed profile. A
superior finish on the wire reduces copper flaking compared
to lower-quality wires.
For fabricating austentic stainless steel ESAB recommends
using the Rebel’s inductance function and running OK Autrod
308LSi to further enhance wetting, reduce weld crown and
improve tie-in. Low carbon reduces the risk of intergranular
corrosion and higher silicon improves the welding properties.
For applications where enhanced corrosion resistance is
required the Rebel can be paired with higher alloyed ESAB
filler metals such as OK Autrod 316LSi.
When galvanised and thin sheet steel (0.8-5mm) are being
fabricated, ESAB’s Coreshield 15 flux-cored wire is suitable
for all-positional, single-pass welding. In addition to producing
a smooth arc, Coreshield 15 ensures full slag coverage, easy
slag removal and low spatter. Light rust and mill scale are
tolerated and this wire needs no shielding gas – which is a
further benefit where portability is important.
For mild- and medium-tensile structural steel applications,
ESAB’s Rebel provides good results when using spray
transfer mode with OK Tubrod 15.14 (E71T-1) flux-cored wire
and either Argon/CO2 or 100 per cent CO2. OK Tubrod 15.14
is an all-position that is universally approved to grade 3 by
all major authorities. When it comes to MMA ‘stick’ welding,
the Rebel offer excellent welding performance considering its
portability and operation from a single-phase supply. To make
the most of this capability, ESAB recommends OK 48.00. This
next-generation E7018-H4R formulation has been engineered
to decrease moisture pick-up in high-humidity conditions that
helps prevent hydrogen cracking and non-porous welds to be
produced even in demanding environmental conditions.
ESAB believes its OK 46.00 is its best all-round rutile
electrode and this filler metal works very well with the Rebel.
OK 46.00 is an E6013 electrode that is relatively insensitive
to rust or other surface impurities, producing smooth weld
beads in all positions, including vertical down and with DC+ for
Rebel. Easy to strike, restrike and remove slag, this electrode
is excellent for short welds, root runs and tacking.
