Welding in TIG mode – with Remote amperage torch
1. Connect the Tig Torch to machine, connect earth lead to machine & work piece.
2. Set to Tig mode pulse off or Tig mode pulse on (Fig4.21)
In welding with pulse in remote torch, the foot pedal controls peak main welding amperage
3. Select 2T or 4T torch operation – (Fig 4.22) - Ensure the PEDAL (remote) led is illuminated.
4. Connect Argon gas and set flow to approx 8-12 LPM
5. Set Gas post flow to 3 x diameter of tungsten width
6. Adjust welding amps knob on machine to desired maximum welding current that remote
torch will go to.
7. Press the torch switch to start welding. (on maximum it will go to maximum amps set on
machine)

All values below are based on using pure argon shielding gas. Other current values may be
employed depending on the shielding gas and application
Welding in STICK MMA (SMAW) Mode
1. Fit MMA electrode holder to + terminal on machine (Fig 3.3)
2. Fit earth lead to - terminal on machine and to work piece (Fig 3.1)
3. Select stick on front panel (Fig 4.15)
4. Place electrode in holder
5. Select desired welding current (Fig 4.24) with selector knob (Fig4.17)
6. Select desired MMA options, Arc Force, Hot start time and Amps (Fig 4.18-20)
7. Strike arc and weld
WARNING!
ELECTRIC SHOCK CAN KILL
When machine is switched to MMA mode, output terminals are always live, take care and do not
touch electrode and earth by person at same time, otherwise electric shock will occur.
The foot pedal has no affect on welding current in MMA mode and the gas flow and high frequency
starting circuit is disabled.
