Frequently Asked Questions - MWR-9045 Ozito

What type of welding wire should I use with the Ozito MWR-9045?

The MWR-9045 is designed for gasless flux-cored wire in sizes 0.8 mm and 0.9 mm. Do not use solid wire with shielding gas.

How do I adjust the wire feed speed?

Turn the wire feed speed knob (located on the front panel) to increase or decrease the speed. Start with a middle setting and adjust based on welding performance.

What should I do if the welder stops working and the thermal overload LED is on?

This indicates thermal overload. Do not turn off the welder; the internal fan will cool it down. Wait up to 10 minutes until the LED turns off, then resume welding.

Can I use this welder on a 15-Amp circuit?

Yes, but ensure the circuit is dedicated and protected by a residual current device (RCD) rated at 30mA or less. Check that extension cords are suitable for the power draw.

How do I change the welding wire spool?

Disconnect from power. Open the top cover, remove the wing nut and drive washer, slide the spool onto the shaft, ensure the wire unwinds in the correct direction, and reattach the washer and nut. Then feed the wire through the drive roller and torch.

What is the correct way to feed the welding wire through the torch?

With the pressure arm released, feed the wire into the flexible inner tube. Remove the shroud and torch tip, then depress the trigger while holding the torch straight to push the wire out. Ensure the earth clamp is not touching the torch.

How do I select the correct current setting?

Use the current control switch to choose 50A for thinner materials or 90A for thicker materials. Always adjust the switch when the welder is not in operation.

Why does the wire feed erratically or not feed at all?

Check the wire drive roller for correct size (0.8/0.9 mm) and groove alignment. Ensure the pressure arm is tightened appropriately. Also inspect the wire for kinks or damage.

What safety precautions should I take when using this welder?

Always wear a welding mask with proper shade, protective gloves, and flame-resistant clothing. Keep a fire extinguisher nearby. Ensure good ventilation and remove flammable materials from the work area.

How do I clean and maintain the MWR-9045?

Disconnect from power before cleaning. Use a dry cloth to wipe the exterior. Check the torch tip and shroud for spatter and clean with a wire brush. Do not open the housing; have a qualified technician service internal components.

Preparation

Before welding ensure that:

• You have read and understand the safety section of this manual.
• There is sufficient ventilation, particularly at the front and rear of the unit.
  • You have an adequate fire-fighting devices on hand.
• You wear adequate protective gear while operating the MIG welder, such as welding gloves and the provided face mask.

1 Ensure that your work piece is securely mounted and is cleaned and prepared ready for welding.

2 Attach the earth clamp to the workpiece so that there is a good electrical connection.

3 Switch the MIG welder

OPERATION

8. WELDING PROPERTIES

There are a range of welding movements used in MIG welding. Generally some form of zig-zag motion is used to ensure the arc acts against both sheets to be welded. Below are some details that may help with the welding process.

Travel Speed

The torch should be moved along at a smooth speed that will give the size of run required. At the same time, the wire is fed downwards to keep the correct welding distance at all times. Excessive travel speeds lead to poor fusion and lack of penetration. While too slow a rate of travel may damage the work piece and can lead to burning a hole through the material.

Electricity

The electricity flows through the wire and will not leave the wire unless it is near an earthed object.

Electricity always finds the fastest path to the earth. When the earth cable clamp is connected to the metal work piece a direct earth connection is created back to the welder. When the wire touches or is near the earthed work piece when the trigger is squeezed, electricity flows through the wire, the metal work piece and then through the earth cable straight back to the welder.

Earth Clamp

Prior to connecting the earth clamp it may be necessary to clean the surface of the work piece using the metal brush. Attach the earth clamp firmly to the work piece ensuring there is good metal to metal contact. Clamp it where it will not be in the way. This clamp provides an earth connection back to the welder.

Welding Wire

There are many variables that you will need to take into account when choosing your welding wire size and type. Below are some of the things you need to take into account when choosing the welding wire:

• Thickness of the material to be welded
• Position and type of welding joint
  • Maximum welding capacity of your welder
  • How much penetration will be required for strength
  • Type of bead desired for the weld
• Whether you are using a shielding gas or not
  • Type of material to be welded

IMPORTANT INFORMATION

DESCRIPTION OF SYMBOLS

Thermal Overload

IF YOUR WELDER OVERHEATS AND THE THERMAL OVERLOAD PROTECTION ENGAGES DO NOT TURN YOUR WELDER OFF AS THE FAN WILL ASSIST IN REDUCING THE COOLING TIME.

All Welders have a feature called a duty cycle.

Duty cycle on a welder refers to the time in which the welder operates during normal welding.

A welder can only weld for a certain continuous period of time before it requires to cool down.

If the internal components of the welder should become hot the welder could overheat. If the welder overheats the Thermal Overload Protection feature will automatically shut down the welder.

THIS CAN OCCUR IN HEAVY USE AND DOES NOT INDICATE A FAULT.

The Welder will cease to weld and the Thermal Overload LED light will turn on. This LED Indication light is just to inform you that your welder is becoming too hot and requires to cool down to protect the internal components of the welder. Do Not turn your welder Off as the welder has an internal cooling fan and this will assist your welder to cool down quicker. Reducing the cooling time will enable you to get back to your welding job quicker.

Depending on how many Amps or how heavy the welding you are doing the cooling time may take up to 10 Minutes for your welder to cool down so you can return to your welding job.
