The curve shown in
Fig.3
below shows “V-A” the external static characteristic of welding power, gradient of curve named slope,
normal means “drop off voltage per 100A”. The curves show the output voltage obtainable in any preset output current because
the “V-A” slope is fixed.

Assembly of wheels: (See fig.2)
4.1.1
Drop the axle brackets (7) through the slots in the rear of the bottom tray (6).
4.1.2
Attach a circlip (9) to one end of the axle (10) and slide a wheel (8) onto the axle and right up to the circlip.
4.1.3
Pass the axle (10) under the tray (6) and through the two protruding brackets (7) until the first assembled wheel is up against
the side of the tray.
4.1.4
Slide the other wheel (8) onto the other end of the axle (10) and secure it by attaching a circlip (9) to the end of the axle.
4.2.
Assembly of front foot: (See fig.2)
4.2.1
Place the foot (5) onto the underside of the tray (6) ensuring that the three holes on the foot align with the holes in the tray.
Fix the foot in place with three self tapping screws.
4.3
Assembly of handle: (See fig.1)
4.3.1
Attach the rear handle bracket (1) to the top of the casing using two self tapping screws. Slide the straight handle (2) into the
bracket (1) and slide the other bracket (3) onto the front end of the handle. Secure bracket (3) with two self tapping screws.
Insert the handle extension (4) into the front end of the handle and secure it with a self tapping screw.
