View Full Version : Need part for Telwin Model #90090
04-10-2008, 05:12 PM
I'm a new member. I have a Telwin Multi-Mig welder Model #90090. It's about 15yr old. I need a new Heat Select Switch (Part #81142). It is a five-position switch: off, 1, 2, 3, 4. When I went to turn it on today, something apparantly broke inside the switch, and it is now jammed.
I understand that the original importer (Triple-A-Specialty Co.) is out of business. Does anyone have a lead on where I can obtain another switch? I hate to throw the unit away. It has worked like a charm for me, for those odd jobs that come up from time to time.
Thanks in advance for any help.

You could contact Telwin in Italy directly.

Shipping across the pond tends to be expensive. But the switch is neither bulky nor heavy.
Their website is available in English language, so there should be some people with the ability to handle your request.

Well, I have located and obtained the power switch for my telwin 90090 welder. Now, I have a new problem:
I have no idea which wire goes onto which terminal, because, in my stupidity, I neglected to mark them when I removed the old switch. There are a total of 8 wires to attach, and the connectors are all the same size. Can anybody help??:mad:

Zap here, my 90090 switch is wired as follows. #1 terminal has the blue wire for the indicator light & a single white wire with a plastic insulator on the spade connector, #3 one bare copper & a white wire with no plastic insulator these wires are bundled together in a cloth heat shield. #2 two white wires no plastic insulators, also bundled in cloth shielding. #4 one bare copper with plastic insulated spade connector also the other blue wire from the indicator light. L1-R one black wire, the last terminal wasen't marked but it is probably L2 & it is a gray wire. Hope this helps 'Zap'

My two blue wires are different. I think my welder is a 90100 though.
Here are my terminals as viewed from the front of the switch. Numbers are in the order they are located on the switch:
Right side of the switch:
2, 4, A1 - Upper right part of the switch
C1, S/L2, R/L1 Lower right part
Left side of the switch:
1, 3, A2 - Upper left
Unmarked terminals on the lower left. The lower left terminals are attached to the lower right terminals except for R/L1.
I'm pretty sure that I have most of the wires correct except for 2 blue wires. I'm thinking they go to R/L1 and S/L2
