OPERATION AND ATTENTION
9.03 INTRODUCTION
AC/ C WIG241P have sticking and AC/ C wig
welding,PULSE/ C wig welding many functions,
which adopt the most advanced inverter technolo-
gy.
The development of inverter gas-shielded welding
equipment profits from the development of the
inverter power supply theory and components.
Inverter gas-shielded welding power source utilizes
high-power component MOSFET/IGBT to transfer
50/60HZ frequency up to 100KHz/40KHz, then
reduce the voltage and commutate, and output
high-power voltage via PWM technology. Because
of the great reduce of the main transformer’s
weight and volume; the efficiency increases by
30%. The appearance of inverter welding
equipment is considered to be a revolution for
welding industry.
The welding power source can offer stronger, more
concentrated and more stable arc. When stick and
work piece get short, its response will be quicker. It
means that it is easier to design into welding
machine with different dynamic characteristics, and
it even can be adjusted for specialty to make arc
softer or harder.
As sticking and arc welding ,outer characteristic of
welding machine is constant current .Welding curr
ent will not be changed with arc length and current
is stable very much .As plasma cutting ,after arc
has pressed forcedly by air which is flowing
rapidly ,temperature is rise to 10000-15000℃ and it
is up to high coinable situation then strong plasma
arc has been formed .Cutting metal rapidly with
plasma arc, heat is concentrated and energy is
used effectively and smooth cutting section can be
got.
AC/ C WIG241P can be used in welding and
cutting of mild steel, stainless steel, alloy steel,
copper and other color metal .It has lightness, high
efficiency, energy-saving, stabilizing and reliable,
The welding machine to meet the temperature rise
of 40 degrees ambient temperature and rated load
cycle requirements.
The welding machine belongs to the CISPR11 first
group equipment.
Welcome to purchase products of our company
and make suggestions, we will try our best to
perfect our products and service.
Various functional options
1. When use MMA（ARC）function.
1) Make sure the cable, holder and fastening
plug have been connected with the ground. Put the
fastening plug into the fastening socket at the
“-“ terminal and fasten it clockwise.
2) Put the fastening plug of the cable to fastening
socket of “+” terminal at the front panel,fasten it
clockwise,and the earth clamp at the of the terminal
clamps the work piece.
3) Please paty attention to the connecting
terminal , C welding machine has two connecting
ways: positive connection and negative
connection.Positive connection:holder connects with
“-”terminal ,while work piece with the “+” terminal.
Negative connection:work piece with the “-”terminal.
Choose suitable way according to working situation.If
unsuitable choice is made,it will cause unstable arc
more spatters and conglutination,If such problems
occurs,problems occur,please chang the polarity.of the
fastening plug.
2. When use TIG function.
4) Connect well the protecting gas source,Gas
supply passage includes cylinder,argon meter and gas
pipe.The joint part of the pipe should be tighten by
hoop or other things in order to prevent leakaged and
air from coming in.
5) Install the air-electricity system plug to the
socket in the panel and fix it clockwise .Air plug of the
cutting torch and arc-keepingcable should be
connected to relevant socket,and fix the screw.
6) Put the loop cable plug to the fastening
socket,and tighten clockwise ,another terminal holds
the work piece.
