1 Why Plasma cutting with portable  15mm oxyfuel cutting 600mm/min  15mm plasma cutting 1016mm/min 69% speed increase

2 Heavy Duty Rails  Heavy duty rails for cutting with EPOCH!  Occur deformation because of heat impact! Length :1800mm

3 Circle cutting options  Circle cutting rail for diameter 40~360mm (inside) and 1150~2400mm (outside)

4 Circle cutting options  Circle cutting attachment for diameter 50~2400mm

5 Snap Valve  One touch On/Off Gas Valve  Set preheating flame  For use of most portables  Efficient

6 Twin torch option  For use on CNC machines and IK-12MAX 3 portable  Accurate strip cutting  Range 32 – 312 strip cutting  Max 40mm thickness (tip # 3)  Installment like cutting nozzle, easy

7 Bevel attachment option  Ease of use  For CNC machine and IK-12MAX 3  Up to 150mm of thickness  Large angle scale setting

8 Torch rack 300mm  Longer rack available when cutting from the side of plate of from bottom is necessary

9 Trackless cutting  Beveling plates without track with puma option

11 IK-72T

12 IK72-T is compact, for all positions suitable, pinion driven cutting machine intended for use at cumbersome places like applications in shipbuilding and transport, or for cutting cylindrical or irregular formed barrels. He can cut material up to 50 mm.

13 1D rail (Straight plane) 2D rail (Double plane) Down + Up 3D rail (Triple plane) Down + Up + Twist The power of the versatility of IK-72T is the choice from three rails which Koike Europe offer. Different rails

14 The rails can be easily connected to the desired length. A set of magnets fix the rail on his position. Because of the big magnetic force a handle is necessary to loose them. Circumstances such as cold, thick painting layers or rust can influence the strength of the magnet negative. The high quality extruded rail result in a smooth movement and stable machine. Connecting different rails

15 The wheels of the IK-72T are assembled on eccenters for grip on the rail and for compensation of wear. Just like all portable machines of Koike Europe there is an abundance to useful appliances: vertical and horizontal adjusting of the burner, bevel adjusting, speed and direction control. With the clutch released you can position or move the IK-72T along the rail with high speed. Long life design

16 In spite of the flexible rail and the small dimensions is the IK-72T extremely strong. The rails have been tested in practice on preheated plates of no less than 300 degrees Celsius and a stainless steel heat shield protects the chassis.

17 Specifications of IK-72T  Cutting thickness:up to 50mm.  Cutting speed:150 – 700 mm/min.  Rail curve:2000mm radius 3D rail (1.5m optimum) 2500mm radius 2D rail  Cutting shape:I, V to 45degr.  Power:42/110/220V AC  Weight:4.5 Kg

18 Specifications of IK-72T  Length of rail:1500mm 1D 1000mm 2 & 3D  Material of rail:Aluminum 1D Flex rubber 2 & 3D  Weight of rail:6.5 Kg

19 IK-05 NEW Portable for Ship building industries

20 The Lug-Cut is a spring driven machine for cutting off lifting lugs on a deck of a ship, bridge or anywhere else. Spring drive method requires no electricity!! Innovation of Lifting Lug cutting!! Designed for heavy duty outdoor use, while the lightweight design makes it easy to use!! Specifications of LUG-CUT

21 The Main Features Innovation of Lifting Lug cutting!! Special curved cutting nozzle. Strong body and easy operation. Light aluminum rail and grip. Equipped with one-touch stop valve. Spring driven device. Uses magnetic track.

22 Manual versus Lug-Cut Innovation of Lifting Lug cutting!! ManualLug-cut Bad Quality No re-use of Lug- Cut Finishing labor (bad quality) Good Quality Re-use of Lug- Cut No finishing labor Cost saving

23 Advantages of IK-05 Lug-Cut Innovation of Lifting Lug cutting!! Curved nozzle for cutting as close as possible to the work piece. Easy of use and light weight only 5.9Kg. No re-adjustment on the flame because of one- touch stop valve. Perfect quality. Can be used on a wet deck. (protection of deck). Saves labor. Re-use of Lug-Cut!! Stable movement of torch.

24 Re-use of Lug-Cut Innovation of Lifting Lug cutting!! The strength of the Lug-Cut machine is that the cut off Lug can be re-used. The cutting surface is so smooth that no grinding is necessary before re- use. With the Lug-Cut machine your Lug has a longer lifetime!! The Lug-Cut machine will save money on labor and buying or creating new ones.

25 Specifications Innovation of Lifting Lug cutting!! Cutting thickness:20 ~ 30mm Cutting speed:400mm/min constant Speed control:Spring drive method Direction of cutting:One direction. Cutting position:Only the horizontal Gas operation:Preset valve Length:740mm Effective cutting length:380mm Weight:5.9Kg Nozzle: (special only#3)106LUG (propane) 102LUG (acetylene)

28 Portable Welding Automation In Shipyard

29 Change the welding process Quality improvements Much Higher productivity Less effect on operator skill Need less operators Lower production cost Lower investment cost

30 Low duty cycle Operator dependency Lower welding output Limited welding length High welding defects Un uniform quality Manual welding

31 Automation with welding carriage Higher and uniformed Quality Not dependent on Operator level Enhances digital welding Fewer start and end of weld Higher welding out put Multiple welding Higher deposit rate Higher welding speed Lower production cost

32 FCW VS Stick (gravity weld)  Higher deposit rate  Higher welding speed  Higher and uniformed Quality  Not dependent on Operator level  Fewer start and end of weld  Lower production cost

41 Welding carriage can weld in high speed and consistent speed. It does not need to stop like stick welding or manual welding. it is possible to have long and stable 3- 5mm fillet weld with welding carriage Increasing productivity and quality. Decreasing welding defect. Small and Long Fillet Welding

42 Multiple machine operation  With welding carriage it is easy to use multiple machines by one operator, often use 2-3 machines per operator

43 Use of welding carriage Multiple welding Higher deposit rate Higher welding speed Quality improvement Non operator dependency Enhances digital welding Lower production cost Improve quality

44 Optimum use in Shipyard welding needs O R= 3,000mm I R= 3,000mm R= 1,000mm θ = 0-90°θ =0~20 ° 90 ° > θ θ =85 ° 90 ° < θ θ =110 ° L = More than 4 0mm Minimum 300mm

46 Multiple machine operation  Supporting system or jigs makes multiple use much easier and more efficient

47 Multiple machine operation  Average use of welding portable machines are 2-3  Maximum of 8-10 are possible with special set up

52 History of Welding Portable Koike has developed the first welding portable in late 80s. From then a few machines are developed, some of them with success some not. With that experience Koike has these days three successful models, like:  Wel Handy Mini,  Wel Handy Multi Standard (STD),  Wel Handy Multi Advance (ADV). The above mentioned welding portables has been developed with the input of the customers, such as shipyards, bridge constructions, fabricators with productivity and ease of use in mind.

53 Features Wel Handy Series  No rail concept (time saving),  Magnet traction (special developed magnet),  4 wheel drive,  Ease of use,  Light weight,  Simple operation,  Multiple operation, The Wel Handy Series are develop with the follow features:
