10. TIG welding selection key
a. 2T – Two-step welding mode. This mode controls only the pre-gas, welding current, post-gas and welding time
that is determined by the I2 setting.
b. 4T – Four-step welding mode. Includes pre-gas, start arc, upslope time, welding current, downslope time and
post-gas functions.
c. Rep – Repeat welding mode. Contains the pre-gas, start arc, slow up, welding current,
slow down and post-gas functions. However the functions differ in Repeat mode:
•
The completion of upslope time into the welding current stage. Quickly press the
torch switch and the welding current switches to the second current as defined by
parameter l2.
•
A long press of the torch switch will cause a gradual reduction in current to the crater
arc and then post gas to complete a welding task.
•
Repeat function supports DC and AC TIG. Pulse or Spot functions are not supported in Repeat Mode.
d. Spot – Spot welding mode. Contains only pre-gas, welding current, post-gas and welding time as set by the
parameter I2. Once the weld is complete, release the torch switch. Press the switch again to finish the welding
process. Spot mode supports DC, AC, Pulse and I-spot welding methods.
11. REMOTE indicator – Select REMOTE and the indicator light will light up. This indicates the
foot pedal can control the welding unit's ON/OFF function and adjust the current. The MAX
working current can be set from 10 to 200A.
12. Power/Alarm indicator
POWER – Lights up when the power switches on.
O.H. – Lights up if the welding unit overheats or if there is an over-voltage or over-current issue.
The display will show Err 000 at the same time.
13. Voltage/other parameter display – Indicates the welding voltage or other parameter.
Before the start of welding, the right-hand display shows the pre-set value of Tpr, Tup, Dcy, Fp,
Tdown, Tspot, I-spot or Tpo. The open-circuit voltage is displayed 3 seconds after adjusting
those parameters.
14. Current display
a. Displays the pre-set or the actual welding current value.
b. The left-hand display shows the pre-set current value of Is, lw, I1, I2, lb and lc before starting to weld.
c. The left-hand display shows the present actual value of the welding current once welding starts
d. The control panel indicates that a position is reached in welding process by brightening the light.
IMPORTANT! Only 'Parameter selection keys' and 'Adjusting dial' can be used in the welding process. Only 'Rod
electrode welding key', 'Adjusting dial' and 'AC/DC selecting key' can be used in MMA mode.
PARAMETER SETTINGS
The light will appear in the selected parameter setting where 2T and 4T mode have been selected (Fig. 7).
