Bought a HF 90a welder and did some welds around 1 year back. Have a reason to use it now .... so decided to upgrade to a TWECO 211i comming this week.
In mean time I thought I might as well practice on my HF 90A. So here are a couple of welds. Would like some advice/tips.https://photos.google.com/share/AF1QipN ... 9MU3ZIaE53
Here's what I think I notice.
1) Areas where I moved to much and not good flow bead.
2) Too much wire in a lot of places - "humps and width".
3) Too high in join at times meaning to much weld in once piece but not in other.
a) I seemed to have a hard time following the puddle with my HF helmet - visibility.
b) Wasnt sure which way the gun should be angled in realtion to my head .... to the left or to the right ...... need to look at some videos and if it matters regarding pulling or pushing so to speak.
c) When you weld - how much of the base metal do you expect to burn out ..... meaning your kinda melting the base metal and backfilling it with metal from rod ...... but sometimes in seems to border on burnthrough ..... but not sure hot to tell how much is normal/good versus bad.
Overall seems ok for 90 A - but really dont know. Got good penetration on first weld.
Excited about the new welder coming and getting into this. Do a car restoration.
