Arc welding gun

To start welding is quite tricky, especially with hand arc welding machine. You need to connect the electrode with the grounded metal and when the spark ignited quickly take it away for a millimeter, but not too far to stop the flame.

Possible solutions:
1 Create some dip paste / gel which can start the current flame and vaporize to open the way for welding metal itself.  It is similar to flux but with more metal powder, enough to run the current and burn out it.  If such paste will work, it would be enough just to dip the electrode and put it on the welling distance.


2 Create the gun which supply the electrode similar to TIG welding (lazy to draw in details).
The electrode 7 connected to wire 1. when you press the trigger 5, the motor 3 start to rotate the belt 2 and push forward the electrode. The nozzle 6 dissipate the heat and could be used as temporal base (I used the angle starting in TIG welding). The handle 4 located closer to the end with constant distance, which help to remember the space and make the welding more easy.
