Welding in TIG mode - No remote foot pedal
1 Connect the TIG torch and earth lead to machine & work piece.
2 Set the TIG/MMA/MIG switch to TIG
3 Select 2 or 4 way torch operation
4 Connect Argon gas and set flow to approx 8-12 LPM
5 Set Gas post flow to 10 Seconds
6 Adjust current to desired welding current
7 Press the TIG torch switch to start welding
Welding in TIG mode - with Remote foot pedal
1 Connect the TIG Torch to machine, connect earth lead to machine & work piece.
2 Connect remote foot pedal to machine
3 Set the TIG/MMA/MIG switch to TIG
4 Select 2 way torch operation
5 Connect Argon gas and set flow to approx 8-12 LPM
6 Set Gas post flow to 5 Seconds
7 Press the foot pedal to start welding.
Note: When welding with remote foot pedal
Pre-set amperage in LED display will show what the maximum amperage foot pedal will go to (what
amperage control knob is set to), upon welding it will show actual welding amperage.
Upon pressing of foot pedal welding arc will start, if you find it hard to start arc push pedal down a bit further
to aid starting.
The benefits of welding with remote foot pedal is greater control of amount of heat going into work especially
beneficial on alloys as these absorb the heat much quicker than steel. Press pedal fully to start weld, upon
weld pool formation you can slightly release the pedal to decrease amperage to sustain perfect weld pool and
increase again as required to sustain weld characteristics.
The foot pedal adjusts from Start (min) current to Max current set on base current knob on front of machine
as shown in LED before welding.
Welding in STICK MMA (SMAW) Mode - no Remote foot pedal
1 Fit MMA electrode holder to machine
2 Fit earth lead to machine and to work piece
3 Select MMA on MMA/TIG/MIG switch
4 Place electrode in holder
5 Select desired welding current
6 Select desired Arc Force
7 Strike arc and weld
