Electric-arc or wire-arc spray equipment system introduction
1, What is Electric-arc or wire-arc spray?
Electric-arc or wire-arc spray is a form of thermal spraying
where two consumable metal wires are fed independently into the
spray gun. The wires are charged and an arc is generated between
them to melt the wire material, which is then entrained in
a compressed air jet from the gun. This molten feedstock is
then deposited onto a substrate. The surface must be
pre-treated by shot blast. The materials typically used are zinc,
aluminum or their alloys such as Zinacor, stainless steel , copper
babbitte, Nickle,bronze,brass ,etc.
2, Aplication ofElectric-arc or wire-arc spray
The device is designed primarily for anti-corrosion coatings of Zn,
Al, but can also be used for spraying decorative or functional
coatings of steels, copper, bronze, brass, etc. A wire
diameter of 2 mm is used as standard, as a special order we
can supply equipment for use of wire diameter 1.6 or 2.5
mm. Standard length of connecting cables is 9 m, length 14 m
is a special order (without inter-connecting link).
3.Advantages of electric- arc spray:
Compare to combustion spray process (using acetylene or propane)
the operating costs are up to 90% less and the work efficiency is
several times higher.
Hand Metallization Coating Equipment
- SM - Hessler 300A LDU- 2 Push
Multi-purpose equipment with great applicability in corrosion
protection. If necessary, the device can be in minutes
switched over to coating application of steel, zinc, aluminum, etc.
- Arc spray gun LD / U 2 with the nozzle for wire diameter 1.6
mm, 2.0 mm or 2.5 mm
- Wire feed set with DC motor (either on a small console or as
a separate device) which can be used to feed the wire into the
nozzle through up to 15m long loom.

Cr-steel --- ---approx 3 to 5 kg/hr
6.Arc spray gun type LD/U-2
Modern electric-arc spray gun with the air motor in the handle,
open or closed system of nozzles for wire dia 1.6 mm, 2.0 mm
or 2.5 mm. Gun can be clamped in the clamping device.
LD / U 2 pistols belong to the best-selling electric-arc spray
guns in the world market.
