When the trigger mode is in the 4 step position the following sequence will occur
Press and hold the Tig torch switch to start sequence.
The machine will open gas valve to start flow of shield gas, after preset gas pre-flow time to
flow time to purge air from torch hose the welding output of machine will be turned on and
the arc will be started at start (min) current
This condition can be maintained as long as required.
Release the Tig torch switch to go to step 2, the machine will now increase output to peak
(main) current in time set by slope-up.
Press and hold the Tig torch switch when main weld is complete
The machine will now decrease the welding output current to finish (min) in down-slope
time set. Once at finish (min) output you can release the Tig torch switch to end weld the
gas post-flow will continue to run for set time.
Foot pedal operation
When using a foot pedal you can adjust the amperage while you are welding by pressing
the pedal, the more you press the more amps you will achieve.
The foot pedal at maximum depression will go to the amperage set in LED before welding.
I.E set the welding amps to 120A and when pedal is fully depressed you will achieve
120Amps.
Foot pedal can't be used with 4T operation, ensure 2T operation is set.
Remote amperage torch
When using a remote amperage torch you can adjust the amperage while you are welding
