WARNING!

Read and understand all safety warnings and instructions carefully before
using this machine. Failure to follow the warnings and instructions may
result in electric shock, re and/or serious injury. Save this manual for
future reference.

Only qualied persons should install, operate, maintain, and repair this unit.

WELDING SAFETY TIPS:

Exposure to a welding arc is extremely harmful to the eyes and skin. Prolonged
exposure to a welding arc can cause blindness and burns. Never strike an arc or
begin welding unless you are adequately protected. Wear re resistant welding
gloves, a heavy long-sleeved shirt, cuess pants, high topped shoes, and a welding
helmet.

CAUTION:
To prevent serious injury, re, and burns:

Keep welding tip clear of grounded objects whenever the unit is plugged in.

WELDING PREPARATION:

An important factor in making a satisfactory weld is preparation. This includes
studying the process and equipment and practicing welding before attempting to
weld the nished product. An organized, safe, ergonomic, comfortable, and a well­lit work area should be prepared for the operator. The work area should specically
be free of all ammables with both a re extinguisher and a bucket of sand available.

To properly prepare for welding with your new welder, it is necessary to:

• Read the safety precautions at the front of this manual.

• Prepare an organized, well-lit work area.

• Provide protection for the eyes and skin of the operator and bystanders.

• Attach the ground clamp to the bare metal to be welded, making sure of good

contact.

• Make sure that the wire-roller groove in the roller corresponds to the diameter

and type of wire being used.

• Plug the machine into a suitable outlet.

SAFETY INSTRUCTIONS

The machine is safe to use due to its plastic cover, which does not conduct electricity.
The welding gun has an overheating protector which prevents operation when the
machine is overheated. The machine is also protected from too low or too high
supply voltage. However, there are some risk factors connected to welding.
You should therefore read and follow the following safety instructions carefnlly.

USE OF PROTECTIVE ACCESSORIES

The arc and its reecting radiation may damage unprotected eyes. Always protect
your eyes and face with an appropriate welding mask. The arc and welding spatters
burns unprotected skin. When welding, always use protective gloves and clothing.

SAFE USE OF THE WELDING GUN

• Parts of the machine, such as the end of the ller wire and welding gun becomes
burning hot during use.

• The wire is also sharp and moves quickly, so be careful when threading it to place.

• Never carry the machine on your shoulder during welding, but place it on an even

surface. DO NOT store the machine by hanging it from the shoulder strap.
The shoulder strap is for carrying only.

• Do not keep the machine near or on hot objects, as the plastic cover may melt.

• Do not move the shielding gas bottle when the control valve is in place.

• Fix the gas bottle securely in an upright position to a separete wall rack or bottle

cart.

• Always close the gas bottle after use.

FIRE SAFETY

Welding is always classied as hot work, so pay attention to re safety regulations.

Protect the environment from welding spatters. Remove inammable material,

such as burning uids, from the vicinity of the welding site and supply the site with
adequate re-ghting equipments. Take into account dangers cauced by special
workplaces, such as re risk and danger of explosion when welding container-like
pieces.

NOTE!

Fire caused by sparks may brake out even after several hours!

CAUTION! Welding in inammable and explosive sites is strictly forbidden!

SUPPLY VOLTAGE

• Do not place the welding machine inside a workpiece, for example in to a container
or a car.

• Do not install or place the welding machine on a wet surface.

• Change faulty cables immediately for they are life threatening and may cause re.

• Ensure that cables are not squeezed or in contact with sharp edges or a hat

workpiece.

WELDING CIRCUIT

• Insulate yourself from the welding circuit by using dry and undamaged protective
clothing.

• Do not work on a wet surface.

• Do not use damaged welding cables.

• Do not place the welding gun or earthing clamp on the welding machine or other

electrical device.

WELDING FUMES

• Make sure ventilation is sufficient.

• Take special precautions when welding metals containing lead, cadmium, zinc,

mercury or beryllium.

• Supply of sufficient clean air can also be ensured with the use of a fresh air mask.

MACHINE USE

The machine is delivered ready for operation without adjustments with 0.8 mm
diameter ller wire. If you use non-recommended ller wire, make sure that the
feed roll groove welding gun contact tip and machine polarity are suited for the
used wire size and type.

BEFORE IMPLEMENTATION

The products are packed to durable packages especially designed for them.
However, always make sure before use that products have not been damaged
