-(Weldability Sheet Thickness (2 x mm): MS Sheet- 0.5mm-3.25mm, Brass Sheet- 0.2mm-1.6mm, Stainless Steel Sheet- 0.3mm-3mm)

-(Weldability Cross Wire/Mesh Application-Wire Diameter (2 x mm): Approx. double the weldability ranges indicated above)

Applications:  Spot Welding, Electro-Brazing, Cross Wire Welding, Sheet Metal- 2-ply or Multi-ply, Mark-less Welding, Resistance Heating and Soldering. Capable of Welding Low Carbon Steel,High Carbon Steel,High Strength Steel,Nickel Alloy,High-Temp Alloy,Titanium. Confirmation of weldability of other materials can be provided on request.

Users Include:   General engineering work-shops, makers of furniture, electrical instruments, containers, barrels and drums, telephone, radio communication devices, clocks, kitchenware, textile machinery and spares, automobiles, bicycles, motor-cycles, scooters, auto-ancillaries, toys, air-conditioners, refrigerators, transformers, motor, switch gear, etc.

Construction : Heavily fabricated with streamlined appearance, suitably stiffened at points of stress. The transformer is mounted directly on to the body and the bearings for the arm are provided in the same.

Cooling System: Electrodes, Electrode holders secondary water cooled, water required to be free from residue forming impurities and at a temperature of less than 30* C or 85* F. If water temperature is higher, increased water flow is required.

Electrodes: One pair Morse Taper II straight electrodes supplied as standard with the machine, Other types available on request.

Adjustment of Electrode Force : Adjustment of Electrode Force by means of Air Pressure. Force is adjustable and gives a constant force from 100 - 200 kgf. by Pneumatic Cylinder, adjusted by Regulating Valve.

Adjustment of Electrode Stroke: By vertical adjustment of electrode holder.

Current Control: Current Control by means of 6 tap change links between 50% and 100%

Weld Initiation: By means of Foot Switch which initiates the weld only after preset pressure is built up.

Electronic Control:Two Timers provided for squeeze and weld. Timings: Short Range 5 - 50 cycles. Long Range 1 - 10 seconds (50 to 500 cycles)

*Weldable Materials-Low Carbon Steel,High Carbon Steel,High Strength Steel,Nickel Alloy,High-Temp Alloy,Titanium, Bronze, Brass

Note: For Bronze and Brass the Weldable thickness reduces and specs are available in table below

* Galvanized Steel Sheet Spot Welding- Galvanizing is a coating of zinc metal that is applied to the steel when it is manufactured, either in a hot dipped fashion or by electroplating. Zinc, when used as a galvanizing coating, protects steel from rust. Galvanized steel requires about 25% more horse power than non-galvanized steel. Weld time and/or weld power need to be increased to spot weld Galvanized steel. Select a higher KVA machine to account for the increased power requirement for spot welding Galvanized steel.

* Power Requirement is 220V AC 50/60Hz or 415V AC 50/60Hz(Price includes customization as per requirement before shipping)

**Butt Welders upto 30KVA can operate on either 2 Lines/Phases 220V (+10%/-10%) or 400V (+10%/-10%) 50/60Hz

***Butt Welders greater than 30KVA can only operate on 2 Lines/Phases 400V (+10%/-10%) 50/60Hz

** Standard Throat Depth is 18"
