Welders

Below find helpful information to help you select the right Welder:
MIG Welding:
An arc welding process which joins metals by heating them with an arc. The arc is between a continuously fed filler metal (consumable) electrode and the workpiece. Externally supplied gas or gas mixtures provide shielding. Common MIG welding is also referred to as short circuit transfer. Metal is deposited only when the wire actually touches the work. No metal is transferred across the arc. Another method of MIG welding, spray transfer moves a stream of tiny molten droplets across the arc from the electrode to the weld puddle.
Consumables: contact tips, shielding gas, welding wire.

MIG Welding Benefits

• All position capability
• Long welds without starts and stops
• Produces nice clean weld
• Can be used on either thin or thick plate metals
• Easy to learn and use

TIG Welding:
This welding process joins metals by heating them with a tungsten electrode which should not become part of the completed weld. Filler metal is sometimes used and argon inert gas or inert gas mixtures are used for shielding.
Consumables: tungsten electrode, filler metal, shielding gas. Three-Phase Circuit-An electrical circuit delivering three cycles within a 360 degree time span, and the cycles are 120 electrical degrees apart.


TIG Welding Benefits

• Superior quality welds
• Can be used with or without filler metal
• Precise control of welding variables
• Free of spatter
• Low distortion

Stick Welding:
An arc welding process which melts and joins metals by heating them with an arc, between a covered metal electrode and the work. Shielding gas is obtained from the electrode outer coating, often called flux. Filler metal is primarily obtained from the electrode core. An AC/DC welder is recommended for Stick. For most applications, DC reverse polarity welding offers advantages over AC, including easier starts and out-of-position welding, smoother arc and fewer arc outages and sticking.
Consumables: stick electrodes.

Stick Welding Benefits

• All position capability
• Portable and simple to operate
• Electrode provides and regulates its own flux
• Low sensitivity to wind and drafts when compared to gas shielded welding

Flux Cored Welding:
An arc welding process which melts and joins metals by heating them with an arc between a continuous, consumable electrode wire and the work. Shielding is obtained from a flux contained within the electrode core. Depending upon the type of flux-cored wire, added shielding may or may not be provided from externally supplied gas or gas mixture.
Consumables: contact tips, flux cored wire, shielding gas (if required, depends on wire type).

Flux Cored Welding Benefits

• All position capability
• Good quality weld metal deposit
• Little skill required
• High deposition rate than Stick Welding

Spot Welding:
A process in which two pieces of metal are joined by passing current between electrodes positioned on opposite sides of the pieces to be welded. There is no arc with this process, and it is the resistance of the metal to the current flow that causes the fusion. Spot welding requires the following equipment: air- or water-cooled spot welder, set of 2 tongs and set of 2 tips.
Consumables: are not required to spot weld.


Spot Welding Benefits

• Fast welding speed
• High rate of production
• Economical

Plasma Cutting:
An arc cutting process which severs metal by using a constricted arc to melt a small area of the work. This process can cut all metals that conduct electricity. Miller Spectrum cutters are complete packages that contain all required equipment and torch consumables.
Consumables: torch consumables, gas or compressed air supply.
