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 60% duty cycle, 130 amperes at 20 volts. This means that it has been designed and built to provide the rated amperage (130A) for 6 minutes, i.e. Arc welding time, out of every 10 minute period (60% of 10 minutes is 6minutes). During the other 4 minutes of the 10 minute period the welding power source must idle and be allowed to cool.

Wire Loading and Threading
Turn machine power switch to the OFF(“0”)position before working inside the wire feed enclosure. Make sure that the wire feed drive roll and the contact tip of the gun match the diameter and type of wire used.

Installation of Wire Spool

Push the spool onto the spindle so that the wire deeds off the bottom of the spool, toward the drive roll.
Push the spool spacer onto the spindle, against the spool.
Slide the spring onto the spool, then press on the spool lock, turning it clockwise to lock the spool assembly onto the spindle.

Wire Threading Details

Release Feed Tensioner and rotate the Idler Arm away from the Feed Roller. Ensure that the visible, stenciled size on the drive roll side facing you matches the wire size being used.
Carefully detach the end of the wire from the spool. Maintain tension on the wire to prevent the spool from unwinding and do not release the wire until after step 8).
Cut the bent portion of wire off and straighten the first 4”(100mm).
Thread the wire through the Wire Inlet Liner, over the Feed Roller, and into the gun liner.
Close the Idler Arm and turn down the Feed Tensioner until the idle roller presses down firmly on the wire. (Now you may release the welding wire ). Make sure the wire is positioned in the groove of the lower feed roller.
The Feed Tensioner on the Idler Arm adjusts the pressure on the wire .Adjust pressure by turning the Feed Tensioner to prevent spool overrun, but still allow smooth and easy wire feeding. Start with the pressure set to an intermediate value. Readjust, if necessary. If the drive roll slips while feeding wire, the pressure should be increased until the wire feeds properly. When feeding the welding wire through the gun, the feed roller, the gun connector block and the gun contact tip are always energized relative to work and ground.
Wire Stick Out
Remove the contact tip and nozzle from the gun.
Turn the machine ON(“1”).
Straighten the gun cable assembly.
Depress the gun trigger switch and feed welding wire through the gun and cable. (Point the gun away from yourself and others while feeding wire). Release the gun trigger after wire appears at the end of the gun.
Turn off the machine.
Install the nozzle and contact tip. Refer to Figure 4. Cut the wire off so the 3/8” to 5/8”(10-15mm) protrudes from the end of the tip.
Turn on the machine. The machine is now ready to weld.

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

Stick-out (distance between the end of the contact tube (tip) and the end of the electrode wire). Maintain at about 10mm stick-out.
Wire Feed Speed. Increase in wire feed speed increases weld current ,Decrease in wire feed
speed decreases weld current.
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

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.
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.
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.

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.

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.
(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 primarily 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 are dragged away from the weld bead. The arc and heat are 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.
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.
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.

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.

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 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.
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.

MAINTENANCE

Safety Matters
Periodic check should be carried out by qualified professionals to ensure safety. The power of the switching box and the welding machine should be shut down before periodic check to avoid personal injury accidents such as electric shock and burns. Due to the discharge of capacitors, checking should be carried out 5 minutes after the machine is powered off.

Tips:

| Safety

All maintenance and checking should be carry out after the power is completely cut off. Make sure the power plug of the machine is pulled out before uncovering the welding machine.
When the machine is powered on, keep hands, hair and tools away from the moving parts such as the fan to avoid personal injury or machine damage.

---|---
**| Periodic check**

Check periodically whether inner circuit connection is in good condition (esp. plugs). Tighten the loose connection. If there is oxidization, remove it with sandpaper and then reconnect.
Check periodically whether the insulating layer of all cables is in good condition. If there is any dilapidation, rewrap it or replace it.

**| Beware of static
** In order to protect the semiconductor components and PCBs from the static damage, please wear antistatic device or touch the metal part of the enclosure to remove static in advance before contacting the conductors and PCBs of the machine internal wiring.

| Keep it dry

Avoid rain, water and vapor infiltrating the machine. If there is, dry it and check the insulation of the welding machine (including that between the connections and that between the connection and the enclosure) with an ohmmeter. Only when there are no abnormal phenomena anymore, can the machine be used.
Put the machine into the original packing in dry location if it is not to be used for a long time.

**| Pay attention to maintenance**

Periodic check should be carried out to ensure the long-term normal use of the machine. Be careful when doing the periodic check, including the inspection and cleaning of the machine interior.
Generally, periodic check should be carried out every 6 months, and it should be carried out every 3 months if the welding environment is dusty or with heavy oily smoke.

Routine and Periodic Maintenance

1. Before Each Use -Check over machine and accessories for any obvious condition that may prevent safe performance or operation, repair or replace items as necessary to correct any abnormal condition.
AFTER 5 MINUTES OF WELDING OR WHEN SPATTER ACCUMULATES ON THE CONTACT TIP:
1. Cleaning Tip and Nozzle- With the power switch in the OFF position, keep the contact tip and nozzle clean to avoid are bridging between them. Bridging can result in a shorted nozzle, poor welds and an overheated gun. Hint: Anti-stick spray or gel, available from a welding supplier, may reduce buildup and aid in spatter removal.

Daily maintenance
The power of the switching box and the welding machine should be shut down before daily checking (except appearance checking without contacting the conductive body) to avoid personal injury accidents such as electric shock and burns.

Daily checking is very important in keeping the high performance and safe operation of this welding machine.
