So I think I'm going to order a mig in the next cpl days.
Questions
1. What size do I order? Won't be used heavy but want something that will handle the odd bit of heavy gauge steel
2. Was going with warrior welders but 2 smaller 1s out of stock
3. Do I order cool touch torch at same time?

What size would you recommend?
How large do you want to weld?

250 amps is about the most you can draw off a single phase supply. You can always run it with a 180 amp torch and .8mm wire at lower amperages for most of your work, and switch in a larger torch and 1mm wire for heavier work. Not as time consuming as you might think, and would give you a lot more flexibility.

You wouldn't even need to switch the torch, just the wire, if you ran only the 250 amp torch but a 180 amp torch is much better for finer work.

I'm not familiar with a 'cool touch' torch- but I presume you mean water cooled. These are really only for production work, 300 amps upwards. Bigger and bulkier plus you need a seperate water cooling unit. Waste of time pairing them with a little single phase 180-250 amp machine.

personally it'd be the 250A all day (I have one of Phil's) ...
can weld smaller stuff with the bigger set, but not vice versa with the smaller set. It's a bigger unit to move about, but perfectly carry-able - will also take a 15kg roll of wire (cheapest way to buy it), but DO NOT leave the wire on the set ..
keep it in the warm and dry or it'll be foo-baahed next time you want to use it :(
the 250 needs a 16A supply to run it full on, but'll happily run off a 13A for most of what you'll need.
as Doob says .. two torches are a good investment - the MB15 is a nice fine torch for light, delicate, fiddly stuff.
if you want to lay it down then an MB25 will bang it down all day (bigger 6mm tips as opposed to the little 6mm tips in a 150 and can also take an 8mm tip carrier for heavy work).
I also have a few MB36s which I'll chuck on if doing prolonged 'heavy' welding ... handle the heat generated, much better, but the MB25 is more than adequate for most stuff.
Also ask Phil for a longer gas delivery hose - at least as long as the mains lead - saves lugging a gas bottle about - can sit where-ever your power source is, that you plug into.
I've always favoured 5m torch length too and the 250A set with 4 roller feed will drive them fine ...PITA having the set too close, even for bench work - can't beat a 5m IMHDO
I even have a 6m x 150A Stehco which is bril for vehicle welding, --- such a light, fine torch - can use it like a pen almost and never get 'hung up'/struggle for access/length

Was thinking 250 but wondering if a smaller would suffice. Be used for general repairs and odd bit of thicker steel occasionally

says it'll run 170A @100% ... but that'd make hard work of much over 6/8mm plate ..... looks to also need a 16A supply as it's equipped with a 16A round plug but can't see a current draw listed on the spec page

Is that the 250 or 180?

The 180. Basically it will weld all day at almost full power (which is good, cheap ones won't) but 180amps will still be very slow/multiple passes on 6/8mm plate (which isn't that thick when it comes to plant repairs)

I would go 250 with .8mm wire to start, and if you find yourself doing some thinner stuff regularly, then splash out on a second torch.

Yeah 250 was what I was edging towards.
I'll give them a ring over the next couple of days both smaller machined saying they are on back order

Some of the r tech mig machines will run a set off MMA leads if you only want to stick a bit of thick stuff together very occasionally.

I have had good service from r tech and I believe a few on here have too. And if you speak to them online they will usually upgrade the package or throw in some consumables FOC.

Yeah was looking at those too a little cheaper than the warriors too

Long term LIDL welder results are in...:rolleyes:

Steel giant Severfield has slipped to a £5.8m pre-tax loss in its interim results after uncovering the need to remediate 12 bridges, nine of which form part of the High Speed 2 (HS2) megaproject.
The York-headquartered firm this morning (26 November) revealed it had set aside £20.4m to resolve structures it had identified as “not in compliance with the client's weld specification requirements”.
This left Severfield with a plunge into the red in the six months to 28 September this year despite a 17 per cent hike in revenue to £252.3m.
It blamed “sub-optimal choices of welding procedures” for the bridge issues but added that these were “exacerbated by limitations in the specified weld testing regime for these projects".
A “comprehensive review” was underway involving clients, insurers and “relevant industry authorities” said the firm.

HS2 bosses confirmed that nine of the 12 sub-standard bridges formed part of the rapid rail link.

A spokesperson for HS2 Ltd said: “We have identified a number of welding defects related to steel fabrication work undertaken by one of our suppliers.
“A comprehensive review has been undertaken to determine the extent of the further action required. We are working closely with the company and our supply chain to address the issue.
“This will not impact on the safety or quality of the operational railway which is being designed to the highest standards.”
The £20.4m set aside by Severfield in this morning's results covers the expected outlay on eight structures, with expenditure on the remaining four as yet less clear.
The firm added that it would “be pursuing all potential recoveries from third parties... with preliminary indications suggesting a good prospect of insurance recovery”.
Severfield insisted the situation did not impact on the safety of any operational bridges, and it is understood the firm is confident that no more than the 12 identified crossings are affected.
Chief executive Alan Dunsmore hailed a strong six months for the firm but warned of challenges ahead.
“In the first half of the year, we have delivered further underlying profit growth and secured some attractive projects which are reflected in our diversified order books,” he said.
“We continue to see some good projects coming to market. However, the predicted recovery in certain sectors has been slower than previously anticipated, and pricing has remained tighter for longer than expected.
“In addition, a number of large project opportunities for FY25 and FY26 have been either delayed or cancelled and, given the current market backdrop, we remain vigilant to the increased risk of delay to expected orders in the short-term.
“Although the wider market backdrop continues to be challenging, our successful track record and diversified activities give us confidence in delivering the targets we have set for the medium-term.”

“sub-optimal choices of welding procedures” 🤣🤣🤣🤣in real speak..- the cheapest quote and the backhanders we got meant we got a sh*t job

So far Severfield has spent £7.1m on testing and remedial works and expects to incur a further £13.3m cost on eight of the projects.

Severfield added that it still needed to agree solutions on four of the remaining structures where weld testing is ongoing.

Yesterday Severfield said it would be pursuing all potential recoveries from third parties, including insurance.

Will we see a few firms go pop before the end of this saga then..?
