Hi Eugene,
Speed onto the hot metal helps after welding.

...speed almost always helps when slogging too slowly .... but your technique looks good.


Maybe these will help you gain some speed and accuracy :

This fella is holding an "Effie" front fender, in the air hammer, while welding - and while planishing.

Torch stays on until the seam is fully welded, in the Hammer.
("Hot planishing" is the old term used in the shops, 50+ years ago.... )


Then, re-setting the Hammer for "nit picking" low spots, or for shrinking high spots down - hot.

When level, the part is removed from the machine and then "metal finished".

A kiss-0ver with the sharp Vixen (a flick of the fingernail should cause a flurry of wispy shavings in the air) shows last bits needing attention.


Then a FIRM backing pad on a 6in circular sander w/180 =

Left side shows needing more planishing.
Note: pattern is specific for 2nd pass. First passes are 90 deg to this.


Yeehaw - you are on track if you can hold your door in your air whacker with one hand and weld with t'other ... air whacker is yer 3rd hand .
