The equipment must be used only for the purpose it was designed for. Using it in any other waycould result in damage or injury. Only trained and certified welder should use this equipment. Operators should respect the safety of others

Prevention against electric shock

Equipment should be installed by a certified welder and operated in accordance with current
operating standards. It is the user’s responsibility to ensure that the equipment is connected to a suitable power supply. Consult with your utility supplier if required. Earth grounding of the work piece is required, please ground it with a separate cable.
Do not use the equipment if the covers are removed. Do not touch the parts which are electrically charged. Turn off all equipment when not in use. Main supply cables and welding cables should be regularly checked for damage and overheating. Do not use worn, damaged, under sized, or poorly jointed cables. Make sure you wear the correct protective clothing, gloves, head and eye protection. Use dry insulating pads or wear shoes to isolate yourself from the ground to prevent the risk of electric shock.
Never touch the electrodes with your hand, wearing gloves are always required while welding.Do not wrap cables over your body.
Ensure that you take additional safety precautions when you are welding in electrically hazardous conditions such as damp environments, wearing wet clothing, and metal structures. Try toavoidwelding in cramped or restricted positions. Ensure that the equipment is well maintained. Repair or replace damaged or defective parts immediately. Carry out any regular maintenance in accordance with the manufacturer’s instructions.

Safety against fumes

Place the device in a well-ventilated location. Keep your head out of the smoke. Do not breathe fumes. Make sure the welding area is in a well- ventilated area. If this is not possible, appropriate fume extraction measures should be taken.
If ventilation is poor, wear an approved respirator. Read and understand Material Safety Datasheets (MSDS) and manufacturer’s instructions for metals, consumables, coatings, cleaners, and degreasers. Do not weld near any degreasing, cleaning or spraying operations. Be aware that the heat and rays of the arc can react with vapors to form highly toxic and irritating gases. Do not weld on coated metal unless the coating has been removed from the welding area, the area is well ventilated, and a supplied air respirator is worn. Coatings on many metals can produce toxic fumes if welded.

Prevention against Burns and Radiation

Arc rays from the welding process produce intense, visible and invisible (ultraviolet and infrared)
rays that can burn eyes and skin. Wear an approved welding helmet fitted with a proper shade of filter lens to protect your face and eyes when welding or watching.
Wear approved safety glasses with side shields under your helmet. Do not use broken or faulty welding helmets.Always ensure there are adequate protective screens or barriers to protect others from lash, glare and sparks from the welding area. Ensure that there are adequate warnings that welding or cutting is taking place.Wear suitable protective flame resistant clothing. The sparks and spatter from welding, hot workpieces, and hot equipment can cause fires and burns Welding on closed containers, such as tanks, drums, or pipes, can cause them to explode. Accidental contact of electrode to metal objects can cause arcs, explosion, overheating, or fire. Check and be sure the area is safe and clear of inflammable material before carrying out any welding.

Protection from moving parts

Stay away from moving parts such as motors and fans when the machine is in operation. For Maintenance, Disconnect all the power supply cable before removing any protections and coverings. When loading welding wire and operating wire feeding, please protect your fingers to avoid inching. Do not point the torch at other people or your body when feeding wire.

Precautions against fire and explosion
Avoid causing fires due to sparks and hot waste or molten metal
Ensure that appropriate fire safety devices are available near the cutting / welding area. Remove all flammable and combustible materials from the cutting / welding zone and surrounding areas. Do not cut/weld fuel and lubricant containers, even if it’s empty. These containers must be carefully cleaned before they can be cut/welded. Always allow the cut/welded material to cool before touching it or placing it in contact with combustible or flammable material. Do not work in atmospheres with high concentrations of combustible fumes, flammable gases and dust. Always check the work area half an hour after cutting/welding to make sure that no fires have begun. Risks due to magnetic fields
The magnetic fields created by high currents may affect the operation of pacemakers or electronically controlled medical equipment. Wearers of vital electronic equipment should consult their physician before beginning any ARC welding, cutting, gouging or spot welding operations. Do not go near welding equipment with any sensitive electronic equipment as the magnetic fieldsmay cause damage.

Redeclarations
Difficulties may arise in assuring class A electromagnetic compatibility for systems installed in domestic locations due to conducted and radiated emissions.
In the case of electromagnetic problems, it is the responsibility of the user to resolve the situation.
It may be necessary to shield the equipment and fit suitable filters on the mains supply. LF Declaration
Consult the data plate on the equipment for the power supply requirements. Due to the elevated absorbance of the primary current from the power supply network, high-power systems affect the quality of power provided by the network. Consequently, connect ion rest r ict ions or maximum impedance requirements permitted by the network at the public network connection point must be applied to these systems. In this case the installer or the user is responsible for ensuring the equipment can be connected, consulting the electricity provider if necessary. Materials and their disposal
The equipment is manufactured with materials, which do not contain any toxic or poisonous
materials dangerous to the operator. When the equipment is scrapped, it should be dismantled separating components according to the type of materials. Do not dispose of the equipment with normal waste. The European Directive 2002/96/EC on Waste Electrical and Electronic Equipment states the electrical equipment that has reached it send of life must be collected separately and returned to an environmentally compatible recycling facility.

Handling of Compressed gas cylinders and regulators
All cylinders and pressure regulators used in welding operations should be handled with care. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve. Always secure the cylinder safely. Never deface or alter any cylinder.

There is voltage output at both output terminals. Set the amperage on the machine suitable for the electrode being used. Ensure you check that you have the electrode polarity correct. Please see below a guide to amperage required

Electrode Diameter(mm)| Welding Current(A)| Electrode Diameter(mm)| Welding Current(A)
---|---|---|---
1.0| 20~60| 3.2| 108~148
1.6| 40~84| 4.0| 140~180
2.0| 60~100| 5.0| 180~220
2.5| 80~120| |

MIG Welding Mode
Switch the welding mode to 0.8mm flux core or 1.0mm flux core welding mode based on the wire you were using. Adjust the “Voltage knob” on the front panel to get proper welding voltage. We will suggest to start with 50% if you are beginner. The “Current knob” for wire feeding speed adjusting, we will suggest to start with30%if you are beginner. Then Operate the torch trigger, and you can start welding. Set the welding current after the above preparation. Short circuiting transfer is mainly fit for electrode wires of diameter flux 0.8/1.0 mm. As a guide for short circuit welding set the welding current according to the table below.

1. Welding speed selecting
   The welding quality and productivity should be taken into consideration for the selecting of welding speed. In the case that the welding speed increases, it weakens the protection effect and quickens the cooling. As a consequence, it is not good for weld bead shaping. In the event that the speed is too slow, the work-piece will be burned through, and a good weld bead will be unavailable. Impractical operation, the welding speed should not exceed 50cm/min.

2. Wire Stick-out
   The increase of the stick-out can improve the productivity, but too long stick-out may lead to excessive spatter, wire breaking and unstable welding. Generally, the stick-out should be10times as the welding wire diameter.

TROUBLE SHOOTING

In the event of a failure of the machine, contact an authorized service agent. The following operation requires sufficient professional knowledge on electric aspects and comprehensive safety knowledge.
