Sherman Tig (Jasic in disguise?)

[gruvan]

Hello. First post here. Been lurking this forum for several years and have received many great tips and tricks. In the past I have mostly tried to master arc and mig(fluss) welding.
But since I now mainly do things in thinner materials and preferably inside my garage (not 100% fireproof), I have come to the conclusion that I need a good TIG at a good price. Hence why I post here.

I have already understood that it is a good machine for my purpose. However, I have some questions, especially regarding the torch. To make nice welds in thin sheet metal, I have understood that No. 9 is preferable. Many here suggest CK Worldwide and their flex head

So my questions If I buy Sherman with pedal...

1. Is there a cheaper alternative to CK Worlwide No. 9? Found the following on aliexpress WP9 TIG Welding Torch Gas-Electric Integrated Rubber Hose Cable Wires 5/8 UNF Quick Connector 4M 35-50 Euro Connector 13Ft

1. What tig dinse connector to buy? /what modification do I need to do?

1. How does the interaction between the pedal and a CK work, Is it possible to start the HF with the pedal?

1. What do I need the switch on the handle for? If I can ignite with the pedal(dumb question)

Thanks in advance

I have a ck no 9 torch, its super small and light, with a very flexible hose. When in use you either use the switch on or off. Or a pedal. Pedals are normally only used at a bench, where you ingnite the arc including hf, then control the current more commonly used with aluminium.
The binzel torch is a cheaper alternative.

A cheap 9 torch will struggle with more than 100 amps ck will be ok to I think its 125 before it gets too hot to use. If you want to be welding aluminium with a small torch you really need a 20 with water cooling.

So had a little play with the sherman on alloy today for the first time properly. Took a couple of short runs to get the feel for it again. Not done any alloy in probably 18months.

114amps straight, 54hz, 24%,
This is straight off the torch button
3mm (1/8" old money) plate.

Hey, do I need a gas adapter for the Kennedy wp17 torches? If so what size?

54hz seams really low. Am I missing something? Sorry complete newbie.

Personal preference although a lower frequency will, in my experience, put more heat in.
I tend to weld around the 60-70Hz mark but others prefer 100 plus.

I was trying to learn at 120hz and never got a decent cleaning action. So dropped the hz as per guidance from one or the head guys at parweld and been working relatively well. But then I'm no pro but still eager to learn.

No gas adapter, but a 35-50 Dinse plug and an M10 x 1 gas hose connector (if you don’t take the one off the old torch)

 

[Lewi kearney]

Very interesting, have been struggling with cleaning myself. Thought it might be the filler rods even though was Scotch brighting and wiping with acetone. When not using filler , it was gleaming.
Have the dinse 35-50, just need the m10 gas connecter, cheers

Ummmm... I use flannel or sponge, soap and water! I would think the Scothbrite would cause excessive chaffing.

So gave a decent run today, building a welding trolley to carry the other welder, cooler, and gas bottles.

Full pictures will be on the welding trolley page.
Same again 3mm alloy
1000mmx500mm with a 50mm fold on the sides with front and rear plates welded on. 5/8" tube bend and welded onto protect the sides from damage and will have areas to hang leads on etc.

Did this with the Sherman.

Knew something wasn't quite right when doing the fillet then this happened

Christ hood what caused that?? Cooler failure or just pipes getting old/frayed.

 

[Hood]

Cooler motor packed up.

Posh, (expensive) CK Torch?

Parweld Pro Grip Max I'm pretty sure; @Hood let me have a shot a few years ago and I bought one soon after!

 

[Hood]

Aye, Parweld Progrip as mentioned. My personal preference is for the Euro style grip, don't like the round ones. The Parweld Pros have lovely flexible hoses as well so perfect for me.

Thought id resurrect this thread instead of starting one, because its to only thread i could find on the sherman 206P!

Despite what anyone says im almost 100% convinced this machine was nailed together by jasic, so much so i bought one, and im now even more convinced...

View attachment 203959
My evidence so far, this is my 206P ^ promptly delivered from Poland with a pedal for the princely sum of £560, a big risk if it goes up in smoke..
First the only difference i can see to the jasic version is the printing on the control panel, the threaded torch gas connection on the front (rectus on the back and includes a pipe connector) the black plastic is not rubberised. Everything else identical.
Second if you look at the cable, its printed xuanhua, same as jasic supply if you look at the jasic 360 model. Ok hardly damning but its another tick.
I have not had it apart but peering in through the vents all the boards have QR code stickers, indicative of a decent quality controlled production environment, also the bus bars are copper, not aluminum or solder laced pcb's.

Fired it up and it has all the features of the jasic, thought it did away with the electrode selection function to save money but its there, again its just down to the printing on the control panel, just not labeled in the sherman. Now this is my first tig, sort of, have an ancient BOC argonarc but never used it...
So started on some AC welding on aluminium i had laying about, as you do first time out
After about half an hour i was getting the hang of it, and then the fan came on, thats right, fan on demand as well!

From my very, very limited experience its a cracking little machine, super smooth View attachment 203962

This is my first attempt at AC and my second time on a tig, have a lot to learn.

So here is an offer, if anyone out there has a jasic 200p they fancy possibly invalidating their warranty by removing the covers, ill do the same to see if they are actually the same inside.
So far im quite pleased with the sherman, being nearly £1000 cheaper than the jasic (£1327 + £180 for pedal) but its a risk, if anything goes wrong im pretty much on my own

How’s this Sherman treating you? I’m looking to get one at the moment and they seem too good to be true

Have you used it much and has it survived?

many thanks

Still going, but I don't use it anywhere near as much as some. I think @Hood would be a better ambassador to its longevity, a bit more industrial usage. Is a huge thread now but the first 5 pages or so pretty much sum everything up

 

[bigegg]

I've done a couple of hundred hours - mines still working fine.
I'm not pushing it even close to the limit, however: 120A max.
