supply compatible dual AC and DC welding characteristics, using for
various welding rod, the black metals, stainless steel and low alloy
steel, widely used and automobiles, shipbuilding, metallurgy, chemicals,
construction and other industries, welding dynamic characteristics of a
good performance gentle, arc stability, calm pool, a small spatter, weld
shape, low noise, "Eighth Five-Year Plan" to promote the use
of new products.
ZXE1 Series AC-DC dual-core action by the Department of Silicon welder
welding transformer, rectifier group reactor, the composition of main
components such as switches.
The welder is simple in structure, convenient operation and maintenance,
less noise and vibration characteristics.
Used for welding, the welding of low carbon steel and low alloy
steel components. Angle was able to make up for DC arc welding defects
caused by magnetic blow.
Used for welding, welding obvious than the stability of exchange
available J507 electrode. stainless steel electrode for high carbon
steel, alloy steel, stainless steel, copper and cast iron materials and
other high technology welding.

Use
ZXE1 Rectifier AC-DC arc welding machine is based on the People's
Republic of China Machinery Industry ministry standard JB/T7835. JB/T7834
design of a new production welder, is a widely used and the use of a
broad product It used rectifier circuit is easy to use, easy in
striking, arc stability, high efficiency and long life、reliability and
maintenance convenient.
Third. The structure
ZXE1 Rectifier AC-DC arc welding Circuit (see figure 1) and the
role of main components are as follows : Introduction
1、A
series of single-phase displacement of ZXE1 magnetic shunt type
transformer B share three core columns, Winding were placed in the first
class action cores on both sides, divided into primary and secondary
windings in two parts, fixed in the main core. Middle-Core for Mobile,
said moving core constitutes Magnetic Circuit. Mobile Core output can be
changed position welding current size.
2、Silicon device composed of four single-phase rectifier elements, or
full-wave bridge rectifier circuit.
3、The output reactor, in which Tandem welding circuit, starting
filter, so the DC rectifier more straight. Arc to stabilize and reduce
the amount of spatter.

Sixth.
The use of maintenance and attention
1、The
dust in a serious and extremely humid climate, before welding power
source connected to ,the input and output should be measured between the
input and output welder and insulation resistance between the shell. If
less than 0.5 MΩ insulation resistance, no electricity, clean handling
and inspection should be dry and remove insulation fault, use only.
2、In accordance with the wiring when the power supply voltage wiring
access welder corresponding screw (tagged), not to connect wrong.
3、Welding machine and welding cable lines should be sufficient
cross-sectional area, and good contacts Connection reliable.
If
longer welding cables, welding cables instead area, welding cables 4V
not exceed the total voltage drop. so as not to affect the quality of
welding.
4、On
the shell with a grounding screw (tagged) to be fitted with the use of
earth to ensure safety.
5、The
overhaul must be released the power lines, to ensure safety.
6、Screws,
threaded bushing location and activities are kept clean and grease.
7、Welders
must use protective equipment when welding, and scald burns from arc.
8、The
use of welding ventilation in order to heat dissipation, long-term use
should be clean internal dust Offline be cleared.
9、Welder
and not getting wet in the open sun.
10、Removed
to avoid the collision damage.
11、A
welder with any corrosive, flammable, explosive articles parked in the
same room.
12、The
by-products manufactured both by the strict testing products, users in
complying with the rules of their use under the conditions of the damage
occurred as a result of poor manufacturing or normal working hours. in
the 12 months after the sale of the factory for free repairs for
customers.
