That looks downright dangerous, having the top section cantilevered off the vertical will encourage the vertical section to bend, even more so if you drill more holes through it to make it adjustable. The top section will only have to deflect a couple of degrees for the jack to slip...

Does your Oxford 110A welder have output terminals for 50V and 80V OCV? If it does then select the 80V terminal. Using the higher OCV makes for easier arc striking particularly with smaller rods.
Let's never forget the old VODEX, used in most of the british shipyards in the old days, bit of a smoky old rod to use but great for 'lashing it in.' Vodex were good in all positions except vertical down, very easy to control but difficult to get a smooth finish on the cap. I think they were...
It will only take seconds to wack the current up 10 - 15 amps and burn a rod on a piece of scrap, what have you got to lose? Many working welders, myself included, pay little or no attention to the current knob / display on a welding set, it's all about what's happening at the business end of...
Garreth, as Drains says, any 6013 should give good penetration right in to the root of a fillet. When you say that you are running the rods at their upper current limit do you feel that they could be run any hotter? Very often the current output displayed on a set can be a long way off the...
A pipe wrap round is one of the most common marking out tools any pipefitter will ever use. It consists of nothing more than a parallel strip of reasonably stiff yet flexible material. The strip is wrapped tightly around the pipe and over itself again, taking care to align the edges of the first...
As Backpurge has already pointed out, codings won't get you a job, they'll only move you up the queue for an interview. In order to get a start you will be required to pass a test in accordance with the customers requirements. Current codings when presented with a CV detailing experience in the...

I remember seeing a 'stacking' system years ago, a big AC oil cooled welder with a Tig add on unit for AC Tig, there was another unit which was plugged in to give DC Tig, can only think it must have been a rectifier?
Definitely a stick weld repair. Cast iron can be welded with or without preheat. If you use pre heat then it should be hot and kept hot, if not using preheat the job should be cool and kept cool, make a choice and stick with it. On something like an engine block I wouldn't bother with preheat...
Definitely a HF Tig add on unit. Pretty useful set as it is able to utilize a DC input for DC Tig or an AC input for AC Tig (continuous HF). Basically converts any AC or DC welder to a HF start Tig welder. There are loads of HF add on units around but most are DC only. Good find and a good price...
A centering head is the tool of choice for marking TDC on a pipe. TDC can be marked very easily using a square and a level. Mark the radius of the pipe on the inside edge of one blade of the square, using the level on the marked blade bring the other blade of the square against the side of the...
Well done on the test pieces. A little more work with the grinder in the prep work would make a world of difference, especially when doing a test piece. Grinding the back of the test coupons in the root area during fitup will improve the appearance of the root. I agree that Filarc 56S is a good...
Some very good advice there Furry Freak, Ebay and local ads are full of cheap welders being sold by people who have attempted to take up welding 'on the cheap' only to become frustrated and disillusioned right from the start. Acceptable welds can be made with budget gear but when learning there...
I hate to see it too, if you really need to burn wire off then tack a small piece of scrap to the leg of the bench, when it gets covered then simply break it off and replace it......simple!
Even a small 250 Dia. pull down cold saw can be very useful for repetetive cutting, especially when fitted with a quicklock vice and a back stop. Material size is going to play a major part in selecting a saw. In order to take advantage of a bandsaws ability to 'stack' cut it has to be a fairly...
If this is nothing more than humorous banter then get used to it, it happens in every workplace. If on the other hand you feel that the guy is acting maliciously then grow a pair of balls.
Rooting with cellulosics (6010) is generally done on electrode positive, certainly the case with something like Fleetweld 5P. Filarc 56S is a 7016, excellent rod for rooting as the thin coating allows you much better access to the root gap than the 7018 with it's thicker coating, also 7016 is...
For the sizes of materials you are working with I would go with a pull down cutoff saw. Something like a Pedrazolli or MEC Brown can be had for a couple of hundred quid second hand. Blades are relatively cheap to buy and have resharpened. Much quieter than an abrasive or TCT saw and much more...
