Installation and Operator Instructions
Read this entire section before installation or operation of the machine.
General Description
The machine is a semiautomatic constant voltage DC arc welder. The machine uses a single phase constant voltage transformer, solid state rectifier and a DC permanent magnet motor for feeding and welding solid steel electrode and flux-cored electrode (for HANDY MIG) and only flux-cored electrode (for HANDY CORE). This machine is ideally suited for individuals having access to 230 volt AC input power and wanting the ease of use, quality and dependability of both metal inert gas (MIG) welding and the Innershield electrode process (self-shielded flux-cored welding). The machine will handle reels of wire up to 1 Kg.
Location and Environment
This machine will operate in harsh environments. However, it is important that simple preventative measures are followed to assure long life and reliable operation.
Do not place or operate this machine on a surface with an incline greater than 15° from horizontal.
This machine must be located where there is free circulation of clean air without restrictions for air movement to and from the air vents. Do not cover the machine with paper, cloth or rags when switched on.
Dirt and dust that can be drawn into the machine should be kept to a minimum.
This machine has a protection rating of IP21. Keep it dry when possible and do not place it on wet ground or in puddles.
Locate the machine away from radio controlled machinery. Normal operation may adversely affect the operation of nearby radio controlled machinery, which may result in injury or equipment damage. Read the section on electromagnetic compatibility in this manual.
Do not operate in areas with an ambient temperature greater than 40°C.
Input Supply Connection
Check the input voltage, phase, and frequency supplied to this machine before turning it on. The allowable input voltage is indicated in the technical specification section of this manual and on the rating plate of the machine. Verify the connection of grounding wires from the machine to the input source.
Make sure the amount of power available from the input connection is adequate for normal operation of the machine. The necessary fuse and cable sizes are indicated in the technical specification section of this manual.
Shielding Gas Connection (only for Handy MIG)
When using the MIG process, a cylinder of shielding gas (appropriate for the metal being welded) must be obtained.
1. Chain the cylinder to a wall or other stationary support to prevent the cylinder from the work circuit and earth ground.
2. With the cylinder securely installed, remove the cylinder cup. Stand to one side away from the outlet and open the cylinder valve very slightly for an instant. This blows away any dust or dirty which may have accumulated in the valve outlet. Install the regulator on the gas cylinder.
3. Attach one end of the inlet hose to the output of the regulator secure with hose clamp. Connect the other end to the Gas Inlet Fitting on the machine and secure with hose clamp. Make certain the gas inlet hose is not kinked or twisted.

Changing Polarity (only for Handy MIG)
1. For Negative Polarity welding (DC-): Refer to below Figure. As delivered, the machine is wired for Negative polarity with the gun cable connected to the Negative (-) output terminal. This is the typical configuration for Flux Cored Welding (FCAW). To complete the installation, connect the work cable’s terminal lug to the Positive (+) output terminal. Make sure that both thumbscrews are tigh.
2. For Positive Polarity (DC+): Refer to below Figure. To wire for Positive polarity, connect the gun cable to the Positive (+) output terminal and the work cable to the Negative (-) terminal. This is the typical configuration for the Metal Inert Gas (MIG) process. Make sure that both thumbscrews are tight.
Controls and Operational Features
Refer to above Figures.
1. Thermal Protection Indicator: The machine has a rated output duty cycle of 20%. If the duty cycle is exceeded, thermal protector will shut off the output until the machine cools to a normal operating temperature. This is an automatic function of the machine and does not require user intervention.
2. Wire Speed Control
3. Power ON/OFF Switch: When the power is ON the welding output and wire feeder are ON (“hot”) when the gun trigger is pressed.
4. Low / High Heat Range Switch: A rocker switch control that gives low or high coarse range adjustment of the power source output voltage.
5. 1 - 2 Fine Heat Adjustment Switch: Allows fine adjustment of the voltage within the selected Low or High output range.

Flux-cored (Innershield) Welding
The recommended electrode for the flux-cored, selfshield process is 0.9 mm diameter Lincoln Innershield NR-211-MP on 0.45 kg spools.
Sequence of Operations for Wire Loading
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 contact tip of the gun match the diameter and type of wire used.
1. Push the spool onto the spindle so that the wire feeds off the bottom of the spool, toward the drive roll.
2. Push the spool spacer onto the spindle, against the spool. If it is necessary, for getting proper breaking torque you should rotate the spool spacer.
3. Slide the spring onto the spool, then press on the spool lock, turning it clockwise to lock the spool assembly onto the spindle.
4. Release the spring loaded thumbscrew and rotate the idle roll arm away from the wire feed drive roll. Ensure that the visible, stenciled size on the drive roll side facing you matches the wire size being used.
5. 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.
6. Cut the bent portion of wire off and straighten the first 100 mm.
7. Thread the wire through the ingoing guide tube, over the drive roll, and into the gun liner.
8. Close the idle roll arm and turn down the thumbscrew 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 lower drive roll.
9. The spring loaded thumbscrew on the idle roll arm can be used as a “brake” to adjust the pressure on the wire. Adjust pressure by turning the thumbscrew to prevent wire overrun, but still allow smooth and easy wire feeding. Start with the pressure set to an intermediate value. Readjust, if necessary. Slightly less pressure may be required when using 0.6 mm wire. If the drive roll slips while feeding wire, the pressure should be increased until the wire feeds properly.
10. Remove the nozzle and contact tip from the gun.
11. Turn the machine ON (“I”).
12. Straighten the gun cable assembly.
13. 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.
14. Turn the machine OFF (“0”).
15. Replace the contact tip. Cut the wire off so that 10 to 15 mm protrudes from the end of the tip.
16. Turn on the machine. The machine is now ready to weld.
Shielding Gas (only for Handy MIG)
When using the MIG process, you will need a cylinder of carbon dioxide (CO2) or argon-carbon dioxide mixed shielding gas. The regulator should be installed on the gas cylinder. An adapter and plastic washer are needed for using 100% CO2 gas. This adapter is available from your local gas supplier.
1. Open the cylinder valve slowly a fraction of a turn. When the cylinder pressure gauge pointer stops moving, open the valve fully.
2. Keep the cylinder valve closed, except when welding. When finished welding:
Close the cylinder valve to stop gas flow.
Depress the gun trigger briefly to release the
pressure in the gas hose.
Turn off the machine.

Welding
1. Select the right welding process based on the type and condition of the pieces to be welded; the environment in which welding is to be done; and the desired finished appearance of the weld.
2. Select and install the welding wire to match the process. Use Genuine Lincoln Electric Brand wire. Wire quality is essential for successful welding.
3. Install the drive roll, contact tip, and nozzle appropriate for the weld process.
4. Check that the polarity is correct for the welding wire being used and that the gas supply, if required, is turned on.
5. Refer to above Figure. Connect the work clamp to the metal to be welded. The work clamp must make good electrical contact to the work piece. The work piece must also be grounded as stated in Welding Safety Precautions in the beginning of this manual.
6. Based on the welding process type and material thickness of the work piece, set the correct wire speed and heat range setting.
7. Based on the weld joint type and orientation of the weld joint, position the gun into the joint at the correct angel.
8. To begin welding, raise your hand shield to protect your eyes and pull the trigger.
9. While welding, travel at a constant speed and maintain an electrode stickout of 9 mm. Follow the correct direction of travel for the process and joint type and orientation.
10. To stop welding, release the gun trigger.
11. When no more welding is to be done, close the valve on the gas cylinder (if used), momentarily operate the gun trigger to release gas pressure, and turnoff the machine.
Cleaning Tip and Gas Nozzle
Clean the contact tip and gas nuzzle to avoid arc bridging between them. Bridging can result in a shorted nozzle, poor welds and an overheating gun. Anti-stick spray or gel, available from a welding distributor, may reduce buildup and aid in spatter removal.
