Duty cycle and Overheating

The duty cycle of a welding machine is the percentage of time in a 10 minute cycle at which the welder can operate the machine at rated welding current.
Example: 60% duty cycle:

Excessive extension of the duty cycle will cause the thermal protection circuit to activate.
The machine is protected from overheating by a temperature sensor.

Input Supply Connection

WARNING
Only a qualified electrician can connect the welding machine to the supply network. Installation the outlet plug to power lead and connecting the welding machine had to be made in accordance with the appropriate National Electrical Code and local regulations.

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.

Controls and Operational Features

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.

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.

MIG Welding
Table below shows the recommended material/gas combinations for MIG welding with solid electrodes.

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.

Shielding Gas Connection (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.

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.

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 spoolmaintain 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.

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.

Maintenance

WARNING
For any repair operations, modifications or maintenances, it is recommended to contact the nearest Technical Service Center or Lincoln Electric. Repairs and modifications performed by unauthorized service or personnel will cause, that the manufacturer’s warranty will become null and void.

Any noticeable damage should be reported immediately and repaired.

Routine maintenance (everyday)

• Check condition of insulation and connections of the work leads and insulation of power lead. If any insulation damage exists replace the lead immediately.

• Remove the spatters from the welding gun nozzle.
  Spatters could interfere with the shielding gas flow to the arc.

• Check the welding gun condition: replace it, if necessary.

• Check condition and operation of the cooling fan.

Keep clean its airflow slots.

Periodic maintenance (every 200 working hours but at list once every year)

Perform the routine maintenance and, in addition:

• Keep the machine clean. Using a dry (and low pressure) airflow, remove the dust from the external case and from the cabinet inside.
• If it is required, clean and tighten all weld terminals.

The frequency of the maintenance operations may vary in accordance with the working environment where the machine is placed.

WARNING
Do not touch electrically live parts.
WARNING
Before the case of welding machine will be removed, the welding machine had to be turned off and the power lead had to be disconnected from mains socket.
WARNING
Mains supply network must be disconnected from the machine before each maintenance and service. After each repair, perform proper tests to ensure safety.
