OPERATION

B-2

 

 

 

A high open circuit voltage setting provides the soft “buttering” arc with best resistance to pop-outs pre- ferred for most welding. To get this characteristic, set the “Current Range Selector” to the lowest setting that still provides the current you need and set the “Fine Current Adjustment” near maximum. For example: to obtain 175 amps and a soft arc, set the “Current Range Selector” to the 190-120 position and then adjust the “Fine Current Adjustment” for 175 amps.

When a forceful “digging” arc is required, usually for vertical and overhead welding, use a higher “Current Range Selector” setting and lower open circuit volt- age. For example: to obtain 175 amps and a forceful arc, set the “Current Range Selector” to 240-160 posi- tion and the “Fine Current Adjustment” setting to get 175 amps.

Some arc instability may be experienced with EXX10 electrodes when trying to operate with long arc tech- niques at settings at the lower end of the open circuit voltage range.

CAUTION

DO NOT attempt to set the “Current Range Selector” between the five points designated on the nameplate. These switches have a spring loaded cam which almost eliminates the possibili- ty of setting this switch between the designated

points.

Idler Operation

Start the engine with the “Idler” switch in the “High” position. Allow it to run at high idle speed for several minutes to warm the engine. See SPECIFICATIONS for operating speeds.

The idler is controlled by the “Idler” toggle switch on the welder control panel. The switch has two posi- tions as follows:

1.In the “High” position, the idler is off, and the engine high speed is controlled by the governor.

2.In the “Auto” position, the idler operates as follows:

a.When welding or drawing power for lights or tools (approximately 100-150 watts minimum) from the receptacles, the engine operates at full speed.

b.When welding ceases or the power load is turned off, a preset time delay of about 15 seconds starts. This time delay cannot be adjusted.

c.If the welding or power load is not re-started before the end of the time delay, the idler reduces the engine to low idle speed.

Auxiliary Power

The AC auxiliary power, supplied as a standard, has a rating of 3.0 kVA of 115/230V AC (60 hertz).

With the 3.0 kVA, 115/230V AC auxiliary power, one 115V duplex and one 230V grounding type receptacle are provided. The circuit is protected with circuit breakers.

The rating of 3.0 kVA permits a maximum continuous current of 13 amps to be drawn from the 230 volt duplex receptacle. Or a total of 26 amps can be drawn from the 115 volt duplex receptacle. The 115 volt duplex receptacle has a configuration which permits 15 amps on the K1406-3 & -5 and 20 amps on the K1406-4 &-6 to be drawn from either half. The total combined load of all receptacles is not to exceed 3.0 kVA.

An optional power plug kit is available. When this kit is specified, the customer is supplied with a plug for each receptacle.

An optional GFCI 115 volt receptacle kit is also avail- able. Note that the use of this GFCI kit reduces avail- able current to 15 Amps from each half of the duplex receptacle and to a total of 20 Amps of available 115 volt power.
