Cylinders can push against moving parts for full extension, but the moving parts must not let the cylinder flex like you see in the video.

I have to echo NortonDommi on your PPE (Personal Protection Equipment). But I have to add - Sunglasses are not effective as welding goggles. You will "sunburn" your eyes and you only have one pair of them. And - that also goes for using the angle grinder to cut metal as well, the sunglasses might be passible, but a proper UV shield should be used. Didn't see the sandals till part way in, just wow.

Also, I noticed you kept trying to get the weld started and you reach over to another place to strike the arc. You should first clean your ground clamp attachment point so it is not so rusty. Second - you should clean your joints - both pieces - so that you have bare metal and not rust to weld through. The weld needs to penetrate both pieces being welded and rust makes it quite diffcullt to get a good joint.
Thanks for your comment. All your points are absolutely right and well taken. I understand that the hydraulic cylinder with a flange interface may be much better since that will support the cylinder closer to the rod . So effectively half the span will be reduced, which will in turn help in preventing buckling under load. I have shown in the picture below.

Also the glasses I am wearing are the ones that I got along with the welding machine. I was not knowing those were mere sun glasses. Since it was supplied by the welding machine manufacturer himself, I guessed it may be of good quality with UV protection too.
I have just started welding work recently and hence I am not an expert by any standard. Will definitely take your suggestion of cleaning joints before welding.
Thanks once again for your valuable feedback..
