MACHINE START-UP:

FIGURE b.3

 

When the machine is turned ON, an auto-test is exe- cuted; during this test only the Thermal LED is ON; after few seconds the Thermal LED turns OFF and the Power ON/OFF LED lights up.

The Machine is ready to operate when the POWER ON LED on the Front Control Panel illuminates green.

FRONT PANEL CONTROLS

Output Current Knob: Potentiometer used to set the output current used during welding.

Power ON/OFF LED:

This LED lights up when the machine is ON.

Thermal LED:

This indicator will turn on when the machine is overheated and the output has been disabled. This normally occurs when the duty cycle of the machine has been exceeded. Leave the machine on to allow the internal components to cool. When the indi- cator turns off, normal operation is again possible.

A. Power Switch:

It turns ON / OFF the input power to the machine.

b. Input cable:

This machine is provided with an input cord and mold- ed plug. Connect it to a grounded outlet.

C. Fan:

The fan is turned ON / OFF by the machine Power Switch.

Current flows through the electrode cable and elec- trode holder to the electrode and across the arc. On the work side of the arc, the current flows through the base metal to the work cable and back to the welding machine. The circuit must be complete for the current to flow.

To weld, the work clamp must be tightly connected to clean base metal. Remove paint, rust, etc. as neces- sary to get a good connection. Connect the work clamp as close as possible to the area you wish to weld. Avoid allowing the welding circuit to pass through hinges, bearings, electronic components or similar devices that can be damaged.

An electric arc is made between the work and the end of a small metal rod, the electrode, which is clamped in a holder and the holder is held by the person doing the welding. A gap is made in the welding circuit (see Figure B.3) by holding the tip of the electrode 1/16- 1/8” away from the work or base metal being welded. The electric arc is established in this gap and is held and moved along the joint to be welded, melting the metal as it is moved.
