Temporary Inverter workaround

MR-1

I am having issues getting my 240 outlet installed and need to temporarily work off of standard 110 outlet. I ordered a couple of inverters for 110 to 220 has anyone else used them? I am trying to source a cable so I can plug the spindle into the inverter but I am having troubles can anyone help me out.

This is the inverter that I have
(Inverter)
Yinleader 2000W Voltage Converter Transformer(110V to 220V OR 220V to 110V) 2000 Watt Step Up/Down Converter 110/120 Volt - 220/240 Volt w/US Power Cord,Circuit Breaker Protection (VTUS-2000)

In the Machine Specs it does talk about a 120/240 transformer

**** “(OR 120VAC, 15 AMPS IF 120V:240V TRANSFORMER IS USED, 1 DEDICATED BREAKER)” ****

"* Power Requirements (NOTE: 110V & 220V INPUTS MUST ORIGINATE FROM THE SAME CIRCUIT BREAKER PANEL)

  • MACHINE

(1) 120VAC OUTLET, 15A MIN, 1 DEDICATED BREAKER

  • SPINDLE

(1) 240 VAC OUTLET, 20 AMPS MIN. 1 DEDICATED BREAKER (OR 120VAC, 15 AMPS IF 120V:240V TRANSFORMER IS USED, 1 DEDICATED BREAKER)

  • TOUCHSCREEN / CONTROL PC (IF PURCHASED)

(2) 120VAC OUTLETS, 15A MIN, 1 DEDICATED BREAKER

  • FLOOD COOLANT PUMP (IF PURCHASED)

(1) 120VAC OUTLET, 15A MIN"

This seems odd though. why is it either 240@20amps or a 120@15amp if using a transformer ?

240@20 4800watts

115@15 1880watts Why so much less if using a transformer?

What i am missing here?

It also says if using a transformer than the power of the spindle is reduced which is fine by me for the interim while i wait for my 240 instalation

You can buy the one that they sell, or look at it’s specs and find a similar one:

I think i already have the same one (or pretty similar) the question is what cable i need to plug the spindle into the inverter it states that it includes “all required power cords” i don’t know what those are.

I believe the back of the MR1 has an IEC C19/20 plug interface for the spindle. So you would need a plug that matches your transformer on the other end. Did your transformer come with any cords at all? Ive never used one, but I always assumed they had standard NEMA receptacles.

It has the same plug as the one sold by Langmuir I just don’t have the plug for between the inverter and the machine I have the plug that goes from the wall (110) to the inverter I just need to get the 220 from the inverter to the machine.

Would this be the right cable to buy?

Cable Leader 12 AWG 20A 250V Power Cord- NEMA 6-20P to IEC 320 C19 (10ft) Amazon.com

So, Im looking at the front of that transformer and I cant make heads or tails out of that plug pattern. It looks like it can accept both 6-15 and 6-20 plugs, but im not sure. I mean, typically if the manufacturer calls for a 15 amp 120v receptacle, you wouldnt have a transformer that could produce 15 amps at 240v, so a 15 amp plug would be sufficient. The other end of the cord you have linked is correct. If they make the same cord in a 6-15, id get both and send the wrong one back to Amazon, haha.
