General Power Tool Safety Warnings

WARNING Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.

• Do not operate power tools in explosive atmospheres. such as in the presence of flammable liquids, gases or dust.
  Power tools create sparks which may ignite the dust or fumes.

• Keep children and bystanders a way while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• Power tool plugs must match the outlet.
  Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges and moving parts.
  Damaged or entangled cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
  Use of an RCD reduces the risk of electric shock.

Personal safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

• Use personal protective equipment.
  Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

Power tool use and care

• Do not force the power tool. Use the correct power tool for your application.
  The correct power tool will do the job better and safer at the rate for which it was designed.

• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments ,changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally .

• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
  Power tools are dangerous in the hands of untrained users.

• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

• Keep cutting tools sharp and clean.
  Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

• Keep handles and grasping surfaces dry, clean and free from oil and grease.
  Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

• Service

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Assembling the welding shield

Preparing for MIG / MAG Welding

Select the required type of welding using the button 15. Also, use the switch 2 to set the welding current on / off mode (2T – welding is carried out with the torch trigger pressed, 4T – the fi rst press of the torch trigger – the start of welding, the second press – the end of welding).

The VRD function is responsible for lowering the open circuit voltage of the source to 12-24 volts safe for humans, i.e. voltage drops when the machine is turned on, but no welding is performed. As soon as the welding process starts, the VRD restores the operating voltage parameters.
The VRD option is relevant in such cases:
The device is operated in conditions of high air humidity; high requirements for safety at the facility; use of welding equipment in small areas.

Burner

The MIG / MAG welding torch consists of a base, a connecting cable and a handle. The base connects the welding torch and wire feeder. Connection cable: A nylon-covered liner is placed in the center of the hollow cable. The inner part of the channel is for wire feeding. The free space between the duct and the hollow cable is used to supply the shielding gas, while the hollow cable itself is used to supply the current.
ATTENTION! Before assembling and disassembling the burner or before replacing components, disconnect the power supply.

Coil installation

Select the required wire according to the welding procedure. The wire diameter must match the drive roll, wire liner and contact tip. Open the side cover of the machine to insert the wire spool. Unscrew the reel seat adjusting screw, put the spool on the reel seat and fi x it with the same screw. The end of the wire should be under the drum, opposite the wire feeder. Use the adjusting screw to adjust the retention force of the spool. The coil should rotate freely, but no wire loops should form during operation. If hinges are formed, tighten the adjusting screw more. If the spool is diffi – cult to turn, loosen the screw.

Loosen and lower the adjuster towards you.
Raise the pinch roller; Cut off the bent end of the wire and thread the wire into the wire liner of the feeder, align it in the channel of the drive roll. Make sure the bore of the roller matches the diameter of the wire;
Place the wire in the welding torch connector bore, release the pinch roller, and return the adjuster to the vertical position.
Adjust the pressure of the pinch roller.

• When welding with steel wire, the V-groove of the drive roll must be used;
• When using flux cored wire, the gear groove of the drive roll must be used (availability depends on the model and equipment of the device).
• When using aluminum wire, the U-groove of the drive roll must be used (availability depends on the model and equipment of the machine).

Wire feed into the welding arm

To feed the wire into the torch sleeve, temporarily turn on the power by switching the switch 6 and press the button 16 (wire feed) until it fi lls the channel of the welding sleeve and leaves the torch. Disconnect the power supply. Note! For free passage of the wire in the cable, straighten it along its entire length. When feeding the wire, make sure it moves freely in the drive roll channel and that the feed speed is uniform. If the feed rate is uneven, adjust the pressure of the pinch roller. Match and screw in a contact tip that matches the wire diameter and install the nozzle.

Semi-automatic welding modes

This machine can work with two types of welding wires: solid copper-coated wire in a shielding gas environment, and self-shielded fl ux-cored wire, in which case a gas cylinder is not required.
Different types of fi ller wire require a different wiring diagram.

Gas welding (GAS) with solid copper-plated wire:

• Connect the short cable with the connector located at the bottom of the front panel of the device to the left connector on the front panel (“+” terminal).
• Fix the grounding terminal on the work piece to be welded, connect the connector on the other end of the cable to the right connector on the front panel (“-” terminal).
• Check the markings on the feed roll according to the wire diameter being used.
• Insert the spool of wire into the slot.
• Feed the wire into the torch by folding back the roll clamp and inserting the wire into the channel through the recess in the roll.
• Close the roller clamp by slightly tightening the clamping screw.
• Make sure to match the hole diameter of the gun tip to the wire diameter.
• Turn on the machine and run the wire until it exits the tip by pressing the trigger on the torch.
• Connect the hose from the gas regulator to the fi tting on the back of the device.
• Open the valve on the shielding gas cylinder, press the torch trigger and adjust the gas fl ow with the reducer (usually the gas fl ow is set as follows: gas fl ow (l / min) = Wire diameter (mm) x 10.
• Set the required welding mode using the controls.
• Begin welding.

Welding without gas (NO GAS) with self-shielded fl ux-cored wire:

• Connect the short cable with the connector located at the bottom of the front panel of the device to the right connector on the front panel (“-” terminal).
• Fix the grounding terminal on the work piece to be welded, connect the connector on the other end of the cable to the left connector on the front panel (“+” terminal).
• Check the markings on the feed roll according to the wire diameter being used.
• Insert the spool of wire into the slot.
• Feed the wire into the torch by folding back the roll clamp and inserting the wire into the channel through the recess in the roll.
• Close the roller clamp by slightly tightening the clamping screw.
• Make sure to match the hole diameter of the gun tip to the wire diameter.
• Turn on the machine and run the wire until it exits the tip by pressing the trigger on the torch.
• Set the required welding mode using the controls.

Welding process

Set the welding current based on the thickness of the material to be welded and the diameter of the electrode wire used. The wire feed speed is automatically synchronized with the welding current. Move the torch to the workpiece so that the wire does not touch the workpiece, but is at a distance of several millimeters from it. Press the torch button to light the arc and start welding. The pressed key ensures the feed of the electrode wire and the fl ow of shielding gas set by the reducer.
The length of the arc and the speed of movement of the electrode affect the shape of the weld

Replaceable polarity operation

Initially, the power contact of the welding torch is connected to “+” on the polarity reversal module. This is REVERSE POLARITY. It is used for welding thin sheet steel to stainless steels, alloy steels and high carbon steels, which are very sensitive to overheating. During DIRECT POLARITY welding, most of the heat is concentrated on the product itself, which causes the root of the weld to deepen. To change the polarity from reverse to direct, it is necessary to switch the output of the power wire on the module from “+” to “-”. And in this case, connect the cable with the earth
clamp to the workpiece by inserting the power cable lug into the “+” terminal on the front panel.
For welding with flux cored wire without shielding gas, DIRECT POLARITY is used. In this case, more heat goes to the product, and the wire and the welding torch channel heat up less.

At the end of welding:

• Remove the torch nozzle from the seam, interrupting the welding arc;
• Release the torch trigger to stop the wire and gas feed;
• Disconnect the gas supply by shutting off the gas supply valve from the cylinder reducer;
• Move the switch to the “off” position – off

Manual arc welding mode (mma)

1. Connect the electrode holder to the “-” terminal of the device, the grounding cable to the “+” terminal of the device (direct polarity), or vice versa, if required by the welding conditions and / or the brand of electrodes:
   In manual arc welding, two types of connection are distinguished: direct polarity and reverse. Connection “direct” polarity: electrode – “minus”, welded part – “plus”. Such a connection and a straight polarity current are appropriate for cutting metal and welding large thicknesses that require a large amount of heat to warm them up. “Reverse” polarity (electrode – “plus”, part – “minus”) is used when welding small thicknesses and thin-walled structures. The fact is that at the negative pole (cathode) of an electric arc, the temperature is always lower than at the positive (anode), due to which the electrode melts faster, and the heating of the part decreases – and the danger of its burnout is also reduced.

2. Set the mode switch to MMA position.

3. Set the welding current according to the type and diameter of the electrode and start welding.

4. The welding current is regulated by the current regulator, the actual value of the current during operation is displayed on the ammeter display.

5. Excitation of the arc is carried out by briefly touching the end of the electrode to the product and withdrawing it to the required distance. Technically, this process can be done in two ways:|
   – By touching the electrode back to back and pulling it up;
   – By striking the end of the electrode like a match on the surface of the product.
   Attention! Do not knock the electrode on the working surface when trying to ignite the arc, as this can damage it and further complicate the ignition of the arc.

6. As soon as the arc strikes, the electrode must be held at such a distance from the workpiece that corresponds to the diameter of the electrode. To obtain a uniform seam, it is further necessary to maintain this distance as constant as possible. It should also be remembered that the inclination of the electrode axis should be approximately 20-30 degrees, for better visual control of the welding seam guidance.

7. When fi nishing the weld, pull the electrode back a little to fi ll the welding crater, and then lift it up sharply until the arc disappears.
