1. INTRODUCTION

MinarcMig™ Adaptive 150 is an easy-to-use MIG welding machine suitable for both hobby and professional use. Before using or doing any maintenance work on the machine, read the operating manual and keep it for further reference.

1.1. PROPERTIES

The welding machine is small, efficient and extremely light. It is easy to carry with the help of a shoulder strap. The machine is suitable for a range of different purposes and the possibility to use a long extention cord eases operation in various sites. It is also suitable for generator use on construction sites.
Welding voltage and wire feed speed are adjusted with one control according to the thickness of the welded sheet. Thus, selecting the right parameters is easy. The length of the arc, or welding heat, is trimmed with another control, and once the right value is found there usually is no need to change it even when welding a thicker or thinner sheet.
The machine’s welding properties are optimum with a steel wire of
0.8 mm diameter. Also, 0.6 mm, 0.9 mm or 1.0 mm solid wire or cored wire can be used as filler wire. Note, however, that the machine is designed for steel wire welding only.

1.2. ABOUT WELDING

In addition to the welding machine, welding outcome is influenced by the piece being welded and the welding environment. Therefore, recommendations in this manual must be followed.
During welding electric current is led with the welding gun’s current nozzle to the filler wire and via that to the welded piece. Earthing cable attached to the workpiece guides the current back to the machine, forming the needed closed circuit. Unrestricted current flow is possible when the earthing clamp is properly attached to the workpiece and the fixing point of the clamp on the workpiece is clean, paintless and rustfree.
Shielding gas must be used during welding in order to prevent air from mixing with the weld pool. Carbon dioxide or a mixture of carbon dioxide and argon is suitable for shielding gas. Some filler wires form a shielding gas from the wire’s filling as it melts thus eliminating the need for a separate shielding gas.

2. 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 carefully.

2.1. USE OF PROTECTIVE ACCESSORIES

The arc and its reflecting radiation damage unprotected eyes. Always protect your eyes and face with an appropriate welding mask. The arc and welding spatters burn unprotected skin. When welding, always use protective gloves and clothing.

2.2. SAFE USE OF THE WELDING GUN

Parts of the machine, such as the end of the filler wire and welding gun, become 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. Also, 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 separate wall rack or bottle cart. Always close the gas bottle after use.

2.3. FIRE SAFETY

Welding is always classified as hot work, so pay attention to fire safety regulations. Protect the environment from welding spatters. Remove inflammable material, such as burning fluids, from the vicinity of the welding site and supply the site with adequate fire-fighting equipment.
Take into account dangers caused by special workplaces, such as fire 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 inflammable and explosive sites is strictly forbidden!

2.4. SUPPLY VOLTAGE

• Do not take the welding machine inside a workpiece, for example in to a container or a car.
• Do not place the welding machine on a wet surface.
• Change faulty cables immediately for they are life-threatening and may cause a fire.
• Ensure that cables are not squeezed or in contact with sharp edges or a hot workpiece.

2.5. 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.

2.6. 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.

3. MACHINE USE

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

3.1. BEFORE IMPLEMENTATION

The products are packed to durable packages especially designed for them. However, always make sure before use that the products have not been damaged during transportation. Check also, that you have received the products you ordered and the instruction manuals needed. Product packing material is recyclable.
Transportation
The machine should be transported in an upright position.
NOTE! Always move the welding machine by lifting it from the handle. Never pull it from the welding gun or other cables.
Environment
The machine is suitable for both indoor and outdoor use, but it should be protected from heavy rain and sunshine. Store the machine in a dry and clean environment and protect it from sand and dust during use and storage. The recommended operating temperature range is -20°C – +40°C.
Place the machine in such a way that it does not come in contact with hot surfaces, sparks and spatters.
Make sure the air flow in the machine is unrestricted.
