The ESAB 2075220 trigger switch is an exact replacement-part listing tied to MT-200 and MT-400 MIG guns. The important ordering question is not whether a trigger switch “looks close.” It is whether the gun model and part number match the service information for the gun already in your hand. Arc Weld currently lists the exact SKU 2075220 – 1 Each as an active product, and Shopify showed two available at the inventory check for this article.
ESAB 2075220: verify the gun before the switch
Arc Weld identifies part 2075220 as a replacement trigger switch for the ESAB MT-200 and MT-400 gun families. Independent welding-parts references also identify 2075220 with those two MT-series guns. That is useful fitment evidence, but it is not a reason to assume every ESAB, Tweco, or similarly shaped MIG gun uses the same switch.
Before ordering, locate the gun model marking, service label, or parts breakdown. If all you know is the welding machine model, that may not be enough: MIG guns are often replaced during the life of a power source, so the gun mounted today may not be the gun originally supplied with the machine.
Do not diagnose a trigger problem from symptoms alone
A trigger that does not start wire feed or welding output can be one possible failure point, but the same symptom can come from a damaged gun lead, loose internal connection, feeder control problem, remote-control circuit issue, or power-source fault. An intermittent trigger can also be mechanical rather than electrical. This article is an ordering guide, not a universal electrical diagnostic procedure.
Disconnect and isolate power according to the equipment manual before opening a gun handle or servicing internal components. If the repair involves energized testing, wiring changes, or a control circuit you cannot positively identify, use qualified service personnel. Do not replace parts by trial and error on an energized welding system.
What to compare before ordering part 2075220
Start with the exact gun model: MT-200 or MT-400. Then compare the existing switch, connector arrangement, handle configuration, and any revision information in the applicable parts breakdown. Preserve the full part number 2075220; dropping digits or searching only for “MT trigger switch” can surface parts for other gun families.
If the gun has already been rebuilt or modified, do not assume the switch currently inside it is the correct reference. Use the gun identification and service documentation as the primary path. Photos are helpful for orientation, but appearance alone is not a fitment specification.
What this listing includes
The connected Arc Weld catalog identifies this item as one ESAB 2075220 replacement trigger switch. It is not the complete MT-series gun, gun handle, conductor tube, liner, nozzle, or contact-tip package. If more than the switch is damaged, identify those parts separately rather than assuming they are included.
For another example of why exact MT-series part numbers matter, see the Weld Support Parts breakdown of the ESAB 998894 MT-series nozzle. Consumables and internal repair parts solve different problems and should be selected independently.
Current Arc Weld product check
At the time this article was prepared, the connected Arc Weld Shopify catalog showed the product as ACTIVE, SKU 2075220 – 1 Each, with two units available at the Arc Weld location. Inventory can change after this check, so use the live product page for the current quantity rather than treating this article as a stock promise.

The safe ordering sequence
Identify the gun, verify the 2075220 part number against the parts information you trust for that gun, inspect the existing wiring and handle for other damage with power isolated, and then order the replacement only when the fit is confirmed. That sequence is slower than guessing from a symptom, but it is much less expensive than installing the wrong switch or overlooking a problem elsewhere in the gun circuit.
Source identity for the current commerce item was verified from the connected Arc Weld catalog and the live Arc Weld product page. Because current ESAB public documentation for this legacy MT-series switch was not located in this run, no unverified electrical ratings, connector type, installation steps, or cross-brand compatibility are claimed here.
