However, it is impossble to distinguish separate pulses from arc during rapid pulse cycle times

2, 4, 8 and 16 ms, controls are working in the normal way. Welding of thin materials can be

considered as one application because there directing arc to narrow range is very important,
or if slow transportation speed is necessary.

3.2.5 Controls for fusion spot welding

1.

Select TIG welding, Demo, 2-function operation and fusion spot welding S24.

2.

Adjust welding parameters as above in point: Controls for continuous welding.

3.

Go with arrow keys S27 to fusion welding point H35. Adjust spot welding time P31 with

+/- keys S28.

Spot welding is working also in 4-function position, then torch switch needs not be pressed

until at start.

3.2.6 Minilog-operation and control for start current

Operation of Minilog is based on two pressings of different length, short and long (over

0,7 s), on torch switch.With long pressing you make first the gas to flow. When the switch is

released,you go through pre-gas time and up-slope current to start current, when lamps H41

and/or H42 are lighted.
If start current has been adjusted onto different value from welding current, you go to welding

current with short pressing. If start current is the same as the welding current, you go directly

to welding current without any additional pressing. After that you can alternate with short

pressings between welding current and basic current levels.

1.

Select TIG welding, Demo, Minilog operation S23 and continuous or pulsed welding.

2.

Adjust the welding parameters as above in point: Controls for continuous welding.

3.

You can adjust start current value with +/- keys S28 either to lower or higher value by

means or display P41. Control range for start current is approx. 30...150 % of welding

current value. When upper pilot lamp H41 is lighted, there is in display reading

exceeding 100 %. When lower pilot lamp H42 is lighted, there is in display reading under

100 %.

4.

Adjust basic current level H43 with +/- keys. Reading will come to display P42.

5.

Stop welding with long pressing, when releasing switch you go to down-slope current

and post gas time. You can start down-slope from any point operation cycle you like.
