The machine will open gas valve to start flow of shield gas, after a 0.5 seconds pre-flow
time to purge air from torch hose the welding output of machine will be turned on and the
arc will be started. After the arc is started the output current will be 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 base (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.

Arc force (Stick – SMAW only)
This provides better arc starting when in MMA stick mode, useful when you are welding
