Operation

Before starting any welding activity ensure that you have 
suitable eye protection and protective clothing. Also take 
the  necessary  steps  to  protect  any  persons  within  the 
area.

MMA

After connecting the welding leads as detailed you will need 
to switch the power switch to “ON”

Select MMA by switching to the MMA welding mode. There 
is voltage output at both  output terminals.

Select the current mode - AC or DC

Set the amperage on the machine suitable for the electrode 
being used. Please see below a guide to amperages 
required. Ensure you check that you have the electrode 
polarity correct.

Set the arc force current percentage as required. This can be 
adjusted during welding.

Standard TIG mode

Connect the TIG torch leads as detailed above. Ensure that a 
suitable  inert  gas  supply  is  connected  and  the  flow  rate  is 
set 

Switch the power switch on the front panel to “ON”

Select the TIG welding mode using the selector switch.

Select  the  TIG  operating  mode  (2T,  4T)  using  the  selector 
switch.

2T:  Press  the  torch  trigger,  gas  valve  opens,  and  HF  arc 
ignition  starts;  Keep  the  torch  2~4mm  away  from  the  work 
piece  to  ignite  the  arc.  When  the  arc  is  established  the  HF 
stops,  and  current  rises  to  the  preset  value;  Release  the 
torch  trigger,  current  decreases  to  the  minimum  value,  and 
then  arc  stops;  Gas  keeps  flowing  for  the  post-flow  time, 
and welding ends.

4T:  Press  the  torch  trigger,  gas  valve  opens,  and  HF  arc 
ignition  starts;  Keep  the  torch  2~4mm  away  from  the  work 
piece  to  ignite  the  arc.  When  the  arc  is  established  the  HF 
stops,  and  current  rises  to  the  preset  value;  Release  the 

torch  trigger,  and  welding  continues  at  the  preset  current 
level.  Press  the  torch  trigger  again  and  release  it,  current 
begins  to  decrease  to  the  minimum  value,  and  then  arc 
stops; Gas keeps flowing for the post-flow time, and welding 
ends.

Select the welding mode AC or DC

Set the welding current to suit the application

Set the downslope time

If  welding  in  AC  mode  then  set  the  cleaning  control 
percentage as required

If  using  a  remote  control  current  device  connect  it  to  the 
socket on the front of the machine

Pulsed TIG mode

Connect the TIG torch leads as detailed above. Ensure that a 
suitable  inert  gas  supply  is  connected  and  the  flow  rate  is 
set 

Switch the power switch on the back panel to “ON”

Select the TIG welding mode using the selector switch.

Select  the  TIG  operating  mode  (2T,  4T)  using  the  selector 
switch.

2T: 

Press the torch trigger, gas valve opens, and HF arc ignition 
starts; Keep the torch 2~4mm away from the work piece to 
ignite the arc. When the arc is established the HF stops, and 
current  rises  to  the  preset  value;  Release  the  torch  trigger, 
current decreases to the minimum value, and then arc stops; 
Gas keeps flowing for the post-flow time, and welding ends.

4T: 

Press the torch trigger, gas valve opens, and HF arc ignition 
starts; Keep the torch 2~4mm away from the work piece to 
ignite the arc. When the arc is established the HF stops, and 
current  rises  to  the  preset  value;  Release  the  torch  trigger, 
and welding continues at the preset current level. Press the 
torch trigger again and release it, current begins to decrease 
to  the  minimum  value,  and  then  arc  stops;  Gas  keeps 
flowing for the post-flow time, and welding ends.

Select the welding mode AC or DC

Select the pulse operating mode using the selector switch
