2 Overview
2.1 Brief Introduction
The MIG series of welding machines
adopts the latest Pulse Width Modulation (PWM)
technology and the Insulated Gate Bipolar Transistor
(IGBT) power modules. It uses switching frequencies
in the 20KHz-50KHz range so as to replace the
traditional line-frequency transformer type welding
machines. These machines are characterized with
excellent dynamic response, portability, compact
size, light weight, low energy consumption, etc.
The MIG series of welding machines uses mixed gases
as shielding gas to achieve gas shielded welding, active
gas（Ar+O2, Ar+CO2）as shielded gas to realize MAG
welding and inactive gas(Ar)as shielded gas to realize
MIG welding.
MIG series of welding machines has built-in automatic
protection functions to protect the machines from over-
voltage, over-current and over-heat. If any one of the
above problems happens, the alarm lamp on the front
panel will be lit and output current will be shut off
automatically for the machine to protect itself and
prolong the equipment using life.
MIG series Features:
1. Digital control system, real-time display
the welding parameters.
2. High performance multifunction power
source (MIG/MAG, MMA &TIG ACDC).
3. Waveform control, stable welding arc.
4. IGBT technology, for low power
consumption.
5. Rated MIG Duty Cycle：
MIG series of welding machine is suitable for
all positions welding for various plates made
of stainless steel, carbon steel, alloyed steel,
copper, titanium, etc, which is also applied to
pipe instalment, mould mend, petrochemical,
architecture decoration, car repair, bicycle,
handicraft, and common manufacture.

2.2 Working Principle
The working principle of MIG SERIES arc
welding machine is shown as the following
figure. Single-phase 110V/220V work
frequency AC is rectified into DC, then is
converted to medium frequency AC by
inverter device (IGBT), after reducing voltage
by medium transformer (the main transformer)
and rectifying by medium frequency rectifier
(fast recovery diodes) and is outputted by
inductance filtering. The circuit adopts current
feedback control technology to insure current
output stably when MMA or TIG. And adopts v
oltage feedback control technology to insure
voltage output stably when MIG. Meanwhile,
the welding current parameter can be adjusted
continuously and infinitely to meet with the
requirements of welding craft.
MIG series welding machine has an excellent volt-
ampere characteristic, whose graph is shown as
the following figure.
The relation between the rated loading voltage U2
and welding current I2 is as follows:
U2=14+0.05I2(V)

2.3 MIG Welding
Definition of MIG Welding
MIG (metal inert gas) welding also known as
GMAW (gas metal arc welding) or MAG
(metal active gas welding), is a semi-automatic
or automatic arc welding process in which a
continuous and consumable wire electrode
and a shielding gas are fed through a welding
gun. A constant voltage, direct current power
source is most commonly used with MIG
welding. There are four primary methods of
metal transfer in MIG welding, called short
circuit (also known as dip transfer) globular
transfer, spray transfer and pulsed-spray,
each of which has distinct properties and
corresponding advantages and limitations.
To perform MIG welding, the basic
necessary equipment is a welding gun, a wire
feed unit, a welding power supply, an
electrode wire, and a shielding gas supply.
Short circuit transfer is the most common
used method whereby the wire electrode is fed
continuously down the welding torch through
to and exiting the contact tip.
The wire touches the work piece and
causes a short circuit the wire heats up
and begins to form a molten bead, the
bead separates from the end of the wire
and forms a droplet that is transferred
into the weld pool. This process is
repeated about 100 times per second,
making the arc appear constant to the
human eye.

Principles of welding
Short Circuit Transfer - Short circuit transfer is the most
common used method whereby the wire electrode is fed
continuously down the welding torch through to and
exiting the contact tip. The wire touches the work piece
and causes a short circuit the wire heats up and begins
to form a molten bead, the bead separates from the end
of the wire and forms a droplet that is transferred into
the weld pool.
This process is repeated about 100 times per
second, making the arc appear constant to
the human eye.
11 www.strata.co.nz
ADVANCEMULTI205P

The pinch causes the forming
droplet to separate and fall
towards the now creating
weld pool.
An arc is created at the
separation of the droplet and
the heat and force of the arc
flattens out the droplet into
the weld pool. The he at of the
arc melts the end of the wire
slightly as it feeds towards
the base metal.
The wir e feed speed
overcomes the heat of the
arc and the wire again
approaches the work to
short circuit and repeat the
cycle.
The wire approa ches the work
piece and touches the work
creating a short circuit between
the wire and the base metal,
because there is no space
between the wire and the base
metal there is no arc and
current flows through the wir e.
The wire cannot support all
the current flow, resistance
builds up and the wire
becomes hot and weak and
begins to melt.
The current flow creates a
magnetic field that begins
to pinch the melting
wire forming it into droplet.

Basic MIG Welding Good weld quality and weld profile
depends on gun angle, direction of travel, electrode
extension (stick out), travel speed, thickness of base
metal, wire feed speed and arc voltage. To follow are
some basic guides to assist with your setup.
Gun Position - Travel Direction, Work Angle: Gun
position or technique usually refers to how the wire
is directed at the base metal, the angle and travel
direction chosen. Travel speed and work angle will
determine the characteristic of the weld bead profile
and degree of weld penetration Push Technique - The
wire is located at the leading edge of the weld pool
and pushed towards the un-melted work surface.
This technique offers a better view of the weld joint
and direction of the wire into the weld joint.
Push technique directs the heat away from the
weld puddle allowing faster travel speeds providing
a flatter weld profile with light penetration - useful
for welding thin materials. The welds are wider and
flatter allowing for minimal clean up / grinding time.
Perpendicular Technique - The wire is fed directly
into the weld, this technique is used primarly for
automated situations or when conditions make it
necessary. The weld profile is generally higher
and a deeper penetration is achieved.
Drag Technique - The gun and wire is dragged
away from the weld bead. The arc and heat is
concentrated on the weld pool, the base metal
receives more heat, deeper melting, more
penetration and the weld profile is higher with
more build up.
flat even weld profile
light penetration narrower weld profile
even penetration
narrow higher
weld profile more
penetration
13 www.strata.co.nz
ADVANCEMULTI205P

Travel Angle - Travel angle is the right to left angle
relative to the direction of welding. A travel angle
of 5°- 15° is ideal and produces a good level of control
over the weld pool. A travel angle greater that 20° will
give an unstable arc condition with poor weld metal
transfer, less penetration, high levels of spatter, poor
gas shield and poor quality finished weld.
Angle to Work - The work angle is the forward back
angle of the gun relative to the work piece.
The correct work angle provides good bead
shape, prevents undercut, uneven penetration,
poor gas shield and poor quality finished weld.
Stick Out - Stick out is the length of the unmelted
wire protruding from the end of the contact tip.
A constant even stick out of 5-10mm will produce
a stable arc, and an even current flow providing
good penetration and even fusion. Too short stick
out will cause an unstable weld pool, produce
spatter and over heat the contact tip. Too long
stick out will cause an unstable arc, lack of
penetration, lack of fusion and increase spatter.

and
Travel Speed - Travel speed is the rate that
the gun is moved along the weld joint and is
usually measured in mm per minute. Travel
speeds can vary depending on conditions
and the welders skil l and is limi ted to the
welders ability to control the weld pool. Push
technique allows faster travel speeds than
Drag technique. Gas flow must also
correspond with the travel speed,
increasing with faster travel speed and
decreasing with slower speed. Travel speed
needs to match the amperage and wil l
decrease as the material thickness and
amperage increase.
Too Fast Travel Speed - A too fast
travel speed produces too little heat per
mm of travel resulting in less
penetration and reduced weld fusion, the
weld bead solidifies very quickly
trapping gases inside the weld metal
causing porosity. Undercutting of the
base metal can also occur and an
unfilled groove in the base metal is
created when the travel speed is too fast
to allow molten metal to flow into the
weld crater created by the arc heat.
Too Fast Travel Speed

undercut
lack of fusion lack of joint penetration

15 www.strata.co.nz
ADVANCEMULTI205P

Too Slow Travel Speed - A too slow
travel speed produces a large weld with
lack of penetra tion and fusion. The energy
fr om the arc dwells on top of the weld pool
rather than penetrating the base metal. This
produces a wider weld bead with more
deposited weld metal per mm than is required
resulting in a weld deposit of poor quality.
Too Slow Travel Speed
large wide bead
lack of fusion
porosity
cold lap
lack of joint penetration
Correct Travel Speed - The correct
travel speed keeps the arc at the leading edge
of the weld pool allowing the base metal
to melt sufficiently to create good
penetration, fusion and wetting out of the
weld pool producing a weld deposit of good
quality.
Correc t Travel Speed
even shaped bead
good side wall fusion
good toe fusion
good penetration
Wire types and sizes - Use the correct wire
type for the base metal being welded. Use
stainless steel wire for stainless steel,
aluminium wires for alumi nium and steel
wires for steel.
Use a smaller diameter wire for thin base
metals. For thicker materials use a larger
wire diameter and larger machine, check the
recommended welding capability of you
machine. As a guide refer to the “Welding
Wire Thickness Char t” on the following page.

ADVANCEMULTI205P

Gas selection - The purpose of the gas in the
MIG process is to protect / shield the wire,
the arc and the molten weld metal from the
atmosphere. Most metals when heated to a
molten state will re act with the air in the
atmosphere, without the protection of the
shielding gas the weld produced would contain
defects like porosity, lack of fusion and slag
inclusions. Addit ionally some of the gas
becomes ionised (electrically charged) and
helps the current flow smoothly.
The correct gas flow is also very important in
protecting the welding zone from the
atmosphere.
Argon Co2 CO2
Penetration Pattern for Steel
Too low flow will give inadequate coverage
and result in weld defects and unstable arc
conditions. Too high flow can cause air to be
drawn into the gas column and contaminate
the weld zone. Use the correct shielding
gas. CO2 is good for steel and offers good
penetration characteristics, the weld profile
is narrower and slightly more raised than the
weld profile obtained from Argon Co2
mixed gas. Argon CO2 mix gas offers better
weld ability for thin metals and has a wider
range of setting tolerance on the machine.
Argon 80% CO2 20% is a good all round
mix suitable for most applications.

2.4 Duty cycle and Over-heat
The letter “X” stands for Duty
Cycle,=which is defined as the portion of
the time a welding machine can weld
continuously with its rated output current
within a certain time cycle (10 minutes).
The relation between the duty cycle
“X” and the output welding current “I” is
shown as the right figure.
If the welding machine is overheating,
the IGBT over-heat protection sensing will
send a signal to the welding machine
control unit to cut the output welding
current OFF and light the over-heat pilot
lamp on the front panel. In that case,
the machine should not be welding for
10-15 minutes to cool down
with the fan running. When operating
the machine again, the welding output
current or the duty cycle should be
reduced.
