Electromechanical Influence Of Welding Machines

In industrial environment, welding refers to a production procedure that joins materials such as metals and thermoplastics. This is typically done by softening the work pieces and adding a filler material, which is often a welding rod, to form a pool of molten material that cools to become a strong joint. Various processes, energy sources and welding machines are used for welding.

Welding equipments and machineries can be generally classified into special categories depending on the type of welding processes and equipment used during the process. Some welding machines use transformers for converting high voltage, low current electricity into high current low voltage. These types of welding machines are the least expensive and allow welders to select the output current.

Other Machines use an internal combustion engine or an electric motor to drive the alternator or generator present in these machines. The process used is similar to transformer based welding machines.

Portable Spot Welder Design Provides Welding Power Equivalent to Many Welders

Shellmax has been manufacturing resistance welding equipment like portable spot welder has been in thousand operations of manufacturing facilities providing consistent quality spot welding in production. Portable spot welder design provides welding power equivalent to many welders much superior in size and costing many times the price. A timed burst of current far in excess of 1000 amperes passes through the metal, heating it to its melting point. Under regular pressure from the arms, the metal fuses together. Overall, the whole welding process takes a fraction of a second. An optional sheet metal stand with a foot pedal activator is available to free the operator's hands for handling materials. For featuring built-in heavy production usage optional reduces sheet metal water cooled arms and tips are solid state timer fabrication costs recommended.


Tips to use of portable spot welder


Galvanized coating is a relatively poor conductor of electricity; galvanized steel does not weld as readily as uncoated steel.

Welding is a suggestion to minimize burn marks on stainless steel: place a piece of copper about 1" square over the side of the metal where do not want a burn mark to appear. Weld the stainless steel through the copper and any burn will be negligible.

For production welding, accomplish the same thing by grinding the tip which rests on the finished surface as broad as possible. File the other tip to a point and you can perform consistent welds on stainless with negligible burn.

Getting the most from welder it is necessary to input power is as high as possible. Therefore recommended, the welder can be connected directly or close to fuse box as possible. If an extension cord is needed, be sure to use at least cables for the best results.

Welding two pieces, the portable spot welder will weld two pieces of round wire together. The diameters of the wires, you can weld deeply exceed the thickness capacity listed for the machines. For best results, contour slots are filed into the tips so that they act as a holding jig when welding the wire.

Producing devices are many uses for the units. It is excellent for heating small metal parts cherry red for hardening. If the thickness of the piece to be hardened is greater, you may have to re-bend the arms slightly.
