Weldmatic W60 Wirefeeder

Features Weldmatic W60 Wirefeeder

• 4 Roll Drive 50W Motor provides consistent, able drive for a array of wires.
• High & Low Acceleration Range provides 1 to 10m/min or 8 to 20m/min speed, giving bigger ascendancy of wire acceleration - decidedly advantageous at lower voltage settings.
• Arc Alpha Ascendancy allows starting acknowledgment to be accomplished acquainted to bond conditions.
• Creep Alpha Mode provides apathetic wire acceleration until bond starts - ideal for aluminium starts.
• Purge allows gas band to be purged, afterwards agriculture wire.
• Inch allows wire to be fed afterwards crumbling gas.
• Latch provides gun about-face activate to alpha and afresh again stop, abbreviation abettor fatigue on continued welds.
• Post Gas allows gas to abide abounding afterwards bond has finished.
• Pre Gas allows gas to breeze afore bond starts.
• Burnback controls how far the wire burns aback to the tip on achievement of the acclimation operation.
• Atom Time provides abbreviate bond times for repetitive atom welds.
• Accomplished Voltage Ascendancy infinate voltage acclimation at the wirefeeders.

Weld Machine

Weld machine engine power source can be obtained from:
- Motor fuel or diesel
- Parent depot

High-voltage electrical energy transferred through several las transformer.
Voltage required by the machine weld usually:
- 110 Volt
- 220 Volt
- 380 Volt

Network between the machines in weld workshop, there is a switch disconnect.

Wel machine that is driven with the motor, suitable for use in the work field or the shop does not have any electricity


Bow weld flame caused by electric current obtained from the weld machine.

Flame occurs when the bow is made a certain distance between the electrode and the work of the cable work.

Machines have two types of weld, namely:
- Weld Machine DC (direct current - direct current weld machine)
- Weld Machine AC (alternating current - weld machine flow back and forth)

Installation of cable secondary, the engine can be arranged weld DC / DCSP to be made or DCRP.
- If the cable is connected electrode negative engine, and the cable connected positive relationship then called straight polarity (DCSP)
- The relationship DCSP, heat relief, a third electrode heating and heating of a two-thirds of work.

Means of working to receive more heat from the electrode.
- If the cable is connected positive electrode machine, and the cable connected so-called negative polarity relationship best (DCRP)

notes:
DCSP = direct current straight polarity
DCRP = revers polarity direct current

- The relationship DCRP, heat relief, two thirds and a third electrode heating heat things work. Means that the electrode receive more heat from the object of
- When used D.C.R.P, is?
This depends on:
- The workplace object
- Position welding
- Electrode materials and wire
- The desired penetration

AC joint on the engine, the cable and electrode cables can be exchanged without affecting the changes that occur in the hot flame bow.

Benefits on the engine D.C among others:
- Stable flame bow
- Can use the electrode plated and not plated
- Can welding plate is thin in relation to DCRP
- Can be used to welding in places narrow and humid

The benefits of AC machines, among others:
- Blazing small bow, so porous the possibility on weld
- Equipment and maintenance is cheaper

Large currents in welding can be arranged with setting tool, with interesting detour handle or pressing, depend on the construction.

Choosing Aluminum Wire

5356 wire has become the most commonly used of all aluminum filler alloys because of its nice strength & its nice feed-ability when used as a MIG electrode wire. it is designed to weld 5xxx series structural alloys & 6xxx series extrusions, simply anything other than castings, because castings are high in silicon. Its three limitation is that 5356 is not suitable for service temperatures exceeding 150 degrees Fahrenheit (65 degrees Celsius). The formation of Al2Mg at elevated temperatures at the grain boundaries makes the alloys prone to stress corrosion. For components that will be anodized after welding, 5356 is recommended over 4043, which turns jet black when anodized.

4043 is designed for welding 6xxx series aluminum alloys. It may also be used to weld 3xxx series alloys or 2xxx alloys. 4043 has a lower melting point & more fluidity than the 5xxx series filler alloys, & is preferred by most welders because it "wets & flows better" & it's less sensitive to weld cracking with the 6xxx series base alloys. 4043 can also be used for welding castings. 4043 also makes brighter looking MIG welds with less smut because it doesn't contain magnesium. 4043 gives more weld penetration than 5356, but produces welds with less ductility than those made using 5356. However, 4043 is not well suited for welding Al-Mg alloys & should not be used with high Mg content alloys such as 5083, 5086 or 5456 because excessive magnesium-silicide (Mg2Si) can develop in the weld structure to decrease ductility & increase crack sensitivity. (One exception to this rule is 5052, which has a low magnesium content.)

TIG - MIG - MAG - oxyacetylene 3 to 5 days

Participants will conduct the following types of welding processes for assembly in various materials.
TIG stands for Tungsten Inert Gas "or" Tungsten "(Tungsten) refers to the electrode and the words" Inert Gas (Inertgas) designate the type of plasma gas used. This welding process falls into the category of processes arc welding electrode not fuse. The arc is created between the electrode refractory (- generator) and the room (+ generator) in a gas stream, in general, it is a gas or a mixture of noble gases.

TIG Welding

Appearance of the TIG welding

TIG welding is an abbreviation for tungsten inert gas welding, tungsten electrodes, welding, using inert gas to the gas shield. Argon gas is used mainly.
How so weak in the wind shield gas and welding of the weld, to work outdoors with you anywhere regardless of where it is generally unsuitable. The air-cooled welding machine 200A and 300A and how many, from a millimeter below the welding material of about 12 millimeters. However, 150A of current in one place so you will not have a torch and the hot hours of continuous use.That, if the water-cooled welding machine torch and 500A are high-power thing is not hot at all.Let's work efficiently using the welder for the content of the delicate task of air-cooled, but heavy compared to the torch.

This is a 1.5mm stainless steel plate is TIG welded.
50A current welding rod one millimeter


This is 2mm to 6mm plate welded to the flanges.
120A Current 2 fillet welding rod welding weaving method because of the tapered groove of the millimeter



This is a 9mm and 20mm plate is being welded to the flanges. A current of 1.6-mm 2 electrode layer 180A first current electrode layer 200A by rolling life of the 2.4-mm



TIG welding is characterized by outstanding I will look shiny surface. After welding drop the color painted on the surface of the hydrochloride. TIG I like many shades of welding, as the product is cool, I'll have the impression that in acids.
