2.3 Description
This MIG130 takes the guess work out of welding with an impressive SYNERGIC SET function that
allows the user to weld like a Pro with no previous welding experience necessary.
2.4 Duty Cycle
The rated duty cycle of a welding power source, is a statement of the time it may be operated at its
rated welding current output without exceeding the temperature limits of the insulation of the
component parts. To explain the 10 minute duty cycle period the following example is used.
Suppose a welding power source is designed to operate at a 20% duty cycle, 120 amperes at 20
volts. This means that it has been designed and built to provide the rated amperage (120A) for 2
minutes, i.e. Arc welding time, out of every 10 minute period (20% of 10 minutes is 2minutes).
During the other 8 minutes of the 10 minute period the welding power source must idle and be
allowed to cool.

4.2 FCAW Basic Welding Technique
FLUX CORED ARC WELDING(FCAW):This is an electric arc welding process which fuses
together the parts to be welded by heating them with an arc between a continuous flux filled
electrode wire and the work. Shielding is obtained through decomposition of the flux within the
tubular wire. Additional shielding may or may not be obtained from an externally supplied gas or
gas mixture. The process is normally applied semi automatically; however the process may be
applied automatically or by machine. It is commonly used to weld large diameter electrodes in the
flat and horizontal position and small electrode diameters in all position. The process is used to a
lesser degree for welding stainless steel and for overlay work.
Weld at a Steady Pace do not weave the arc, neither forward,backward,of sideways remove slag
with the Chipping Hammer to expose weld for Horizontal Weld Joins.
Remember:Drag if there’s Slag ,Refer to manual for Troubleshooting Poor Weld Quality.
Adjustable Variables
1) Stick-out (distance between the end of the contact tube (tip) and the end of the electrode
2) wire). Maintain at about 10mm stick-out.
3) Wire Feed Speed. Increase in wire feed speed increases weld current ,Decrease in wire feed
4) speed decreases weld current.
5) Nozzle Angle. This refers to the position of the welding gun in relation to the joint. The transverse
angle is usually one half the included angle between plates forming the joint. The longitudinal angle
is the angle between the center line of the welding gun and a line perpendicular to the axis of the
weld. The longitudinal angle is generally called the Nozzle Angle and can be either trailing (pulling)
or leading (pushing). Whether the operator is left handed or right handed has to be considered to
realize the effects of each angle in relation to the direction of travel.
Establishing the Arc and Making Weld Beads
1) Before attempting to weld on a finished piece of work, it is recommended that practice welds be
made on a sample metal of the same material as that of the finished piece.
2) The easiest welding procedure for the beginner to experiment with MIG welding is the flat
position. The equipment is capable of flat, vertical and overhead positions.
3) For practicing MIG welding, secure some pieces of 1.5mm or 2.0mm mild steel plate 150X
150mm. Use 0.8mm flux cored gas less wire or a solid wire with shielding gas.
4.3 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 (amperage) and arc voltage. To
follow are some basic guides to assist with your setup.
1) Gun Position -ravel 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.
Digital Welder Expert, Know You More
https://www.arccaptain.com

14
(A) 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.
(B) 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.
(C) 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.
2) Travel Angel
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.
3) 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.
Digital Welder Expert, Know You More
https://www.arccaptain.com

15
4) 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.
4.4 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 skill and is limited 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 will decrease
as the material thickness and amperage increase.
1) 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.
2) Too Slow Travel Speed
A too slow travel speed produces a large weld with lack of penetration and fusion. The energy from
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.
3) Correct Travel Speed
Digital Welder Expert, Know You More
https://www.arccaptain.com

16
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.
4.5 MMA and TIG Installation
(MMA) (TIG)
1) A primary power supply cable is available for this welding machine. Connect the power supply
cable to the rated input power.
2) The primary cable should be tightly connected to the correct socket to avoid oxidization.
3) Check whether the voltage value varies in acceptable range with a multi-meter.
4) Insert the cable plug with electrode holder into the “-” socket on the front panel of the welding
machine, and tighten it clockwise.
5) Insert the cable plug with earth clamp into the “+” socket on the front panel of the welding
machine, and tighten it clockwise.
6) Ground connection is needed for safety purpose.The connection as mentioned above in 4) and
5) is DCEN connection. Operator can choose DCEP connection according to workpiece and
electrode application requirement. Generally, DCEP connection is recommended for basic
electrode, while there is no special requirement for acid electrode.
7) Insert the cable plug with TIG Welding torch into the “--” socket on the front panel of the welding
machine, and tighten it clockwise.
8) Insert the cable plug with earth clamp into the “+” socket on the front panel of the welding
machine, and tighten it clockwise.

• Disconnect the machine completely from the mains.
• Remove the mains plug.
• Wait for 5 minutes until the capacitors have discharged.
Electric Shock can kill
• Turn the input power OFF at he welding power source before installation or changing drive rolls
and/or guides.
• Do not touch electrically live parts.
• When inching with the gun trigger, electrode and drive mechanism are “hot” to work and ground
and could remain energized several seconds after the gun trigger is released.
• Do not operate with covers, panels or guards removed or open.
• Only qualified personnel should perform maintenance work.
Items Requiring No Maintenance
• Drive Motor and Gearbox - Lifetime lubrication
• Wire Reel Spindle - Do NOT lubricate shaft
Routine and Periodic Maintenance
•Before Each Use -Check over machine and accessories for any obvious condition that may
