Connections for TIG (GTAW) Welding 

 

 

 

Fig 2 

 

 

1. 

 Negative power connector -

 

 

Connect Tig Torch Dinze to power connector by inserting and twisting until tight 

 

2. 

Gas outlet

 

 

Connect the torch gas hose 

 

3. 

Positive power con

 

 

Connect the earth lead to by inserting and twisting until tight and the earth clamp to 

work/bench 

 

4. 

Torch control socket 2-Pin

 

 

                Connect torch control plug 

 

 

To avoid a High Frequency shock keep the Tig torch in good condition and replace if any of the 

insulation is damaged. 

 

 

Connect the gas input hose to gas regulator and use ‘Pure Argon’ Gas, available from local 

suppliers. Set gas flow/pressure to 8-12 LPM. 

 

Make sure gas bottle is secured to avoid injury.
