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.

Innovative inverter spot welder development by Shellmax

Now a day’s automotive industry, high strength steels require a lot of energy to weld without overheated. The Shellmax inverter spot welder simply works with steels and features with double action capability allow the user to move promptly and without difficulty between welding positions for superior productivity.

The completely featured spot welder is air-cooled with two fans and overheats warning for protection.

The S12-3 Inverter Spot Welder will handle up to a highest of 12,000 amps, with inverter frequency of up to 2,000 Hz. The welding gun is versatile using stainless steel and will allow the user do single-sided and double-sided spot welding.

The smart control panel has operating modes to hold up to 40 welding programs. Inverter spot has memory function to grasp user set operating mode and programs will recall later.

The S12-3 easily welds steel, zinc-coated steel, galvanised steel used in motor vehicles. S12-3 Inverter Spot Welder is automatic adhesive detection and adjustment, plus energy control for heat wounded, by maintenance flat energy levels according to thickness and quality of sheets being welded. The S12-3 has arm to follows the operator wherever the spot gun is positioned for welding.

Spot Welder Electro Mechanical Characteristics

Welding by spot welder is an electro mechanical development in which combining only applicable metal are joined together by the heat accessible from opposing capacity to electric current flow. Metal on work is being done are detained mutually under complete control pressure of exerted electrodes.

Characteristically the metal sheets are in the 0.5-3.0 mm thickness capacity. The welding work progression uses two shaped copper alloy electrodes to deliberate welding power into a tiny SPOT and to at the same time hold tightly the sheets together.

After applying certain amount of force of bulky current through the spot will melt the metal and form the weld. The nice-looking characteristic of welding through inverter spot welder is a lot of force can be delivered to the spot in a very short time. That permits the welding to take place without extreme heating to the remaining of the metal used.

The amount of heat applied to the spot is dogged by the confrontation between the electrodes and the amplitude and duration of the supplied power. To be appropriate too little energy will not be melting the metal or will build a low quality weld.

If a welder is applying more amount of energy then because certain properties of metal it will melt more, eject molten material, and generate a hole instead of a weld. An additional striking feature of spot welding is the energy transported to the spot can be completely in command to create dependable welds.

Spot welding is characteristically consumed when welding only meticulous types of sheet metal. Substantial stock is more complicated to spot weld, the reason is for it, is the heat streams into the nearby metal more straightforwardly.

Certain unique characteristic metal alloys can be spot welded, but their large amount of thermal conductivity as well as electrical conductivity requires elevated welding powers. This requires better, extra influential and additional exclusive welding machine capacity.
