How we scored them

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Cut capacity and power

Amps run 50 to 65 here. The SILATU is the top-amperage pick: 65A with a 15 to 40A range at 110V and 15 to 65A at 220V, cutting 12mm at 40A and 60PSI on 110V and 20mm at 65A and 70PSI on 220V. The YESWELDER is 55A with a 20 to 55A output: ideal clean cut 19/64 in at 110V and 25/64 in at 220V, max cut 9/16 in at 110V and 17/24 in at 220V. The PRIMEWELD is a 50A plasma side of a 3-in-1 combo with a stated 1/2 inch clean cut, plus 200A TIG and 200A stick welders. The GUOZHI is 50A with a recommended max of 1/4 in (12mm) at 35A 110V 50PSI and 3/4 in (20mm) at 50A 220V 65PSI. Three state a 60% duty cycle: the SILATU, the PRIMEWELD and the GUOZHI.

Power supply needs

All four run dual 110V/220V. The SILATU listing requires a circuit breaker rated at 40 amps or higher and a dedicated circuit at 220V, or the breaker will trip. The GUOZHI lists breakers up to 40A at 110V and up to 30A at 220V. The YESWELDER is rated 5.6 KW. All four need dry compressed air: the GUOZHI states it connects in about 1 minute with a 1/4 in industrial D-type plug, and the SILATU states its built-in air sensor with a quick-connect 1/4 NPT fitting, with the compressor bought separately. Weights run 13 to 32 pounds: the GUOZHI states 13 lb, the SILATU 13.45 lb, the YESWELDER 20.9 lb and the PRIMEWELD 32 lb.

Listing notes and contradictions

A few stated oddities. The YESWELDER states a max cut of 17/24 in at 220V, an unusual fraction; take it as stated. The PRIMEWELD bullet says it can cut metals “up to 1/2-foot thick”, a clear typo for 1/2 inch; the clean cut figure of 1/2 inch wins. The SILATU title states a 4/5 in max cut and 9/16 in clean cut, while the bullets state 12mm and 20mm figures; the bullet figures win. Warranty: the PRIMEWELD states a 3-year warranty, the YESWELDER 2 years, and the SILATU and GUOZHI 1 year each. The SILATU also states lifetime technical support.

Duty cycle and current ranges

What the 60 percent figure covers

Three of the four listings state a 60 percent duty cycle: the SILATU, the PRIMEWELD and the GUOZHI. The SILATU states 15 to 40A at 110V and 15 to 65A at 220V, so its 60 percent duty cycle applies across those ranges. The PRIMEWELD states 60 percent duty cycle at max amps for all functions, meaning the plasma side and the welder sides share the same rating. The GUOZHI states 60 percent duty cycle with 50/60Hz high-frequency output. The YESWELDER states no duty cycle figure, so treat its continuous-run limits as not stated.

Current ranges and what they mean

The stated current ranges differ per voltage. The YESWELDER outputs 20 to 55A across its range. The SILATU runs 15 to 40A at 110V and 15 to 65A at 220V, the widest span here. The PRIMEWELD is 50A plasma plus 200A on the TIG and stick sides. The GUOZHI is 50A with recommended settings of 35A at 110V and 50A at 220V. Lower current suits thinner stock: the SILATU’s 15A bottom end at 110V is the lowest starting point of the four, while the YESWELDER’s 20A bottom is the highest.

Pilot arc and torch differences

Pilot arc is stated on all four, but the details differ. The YESWELDER states a non-touch pilot arc on the AG60 torch that cuts rough, painted and rusty surfaces without touching the tip to the metal, plus PT/2T/4T function with a recommended 5 to 8 second post-time cooling period. The SILATU states a high-frequency non-contact pilot arc with a PA adjustable function that extends pilot arc maintenance time, and PT adjustable between 3 and 15 seconds with 4 to 10 seconds generally recommended. The GUOZHI states pilot arc function with 2T/4T and a trial function. The PRIMEWELD states pilot arc cutting as part of its 3-in-1. Longer post-time cooling extends consumable life per the YESWELDER and SILATU listings, so the adjustable PT on those two is the consumable-life feature here.

Air supply details

Pressure and flow per listing

Stated air needs differ. The SILATU states 60PSI at 40A on 110V and 70PSI at 65A on 220V, with a recommended flow rate of 250 liters per minute and a quick-connect 1/4 NPT fitting; the air compressor is bought separately. The GUOZHI states 50PSI at 35A 110V and 65PSI at 50A 220V, with a 1/4 in industrial D-type plug connecting in about 1 minute. The YESWELDER includes an air compressor filter and gas hose in the box, plus a PC10-02 air connector. Dry, non-hazardous compressed air is stated on the YESWELDER and GUOZHI listings; moisture in the line hurts cut quality, which is why the included filter on the YESWELDER and the internal filter on the SILATU matter.

Digital displays and error codes

All four state a digital display. The YESWELDER states its display shows air pressure, voltage and current with an error code system. The SILATU states a large digital display showing air pressure, voltage and current, with error codes for troubleshooting. The GUOZHI states a digital display. The PRIMEWELD states no display type but does state full-bridge design and soft-switching technology for stable arcs at low temperatures. For a first-time buyer, the error-code displays on the YESWELDER and SILATU are the diagnostic feature; the GUOZHI and PRIMEWELD state no such system.

Home wiring reality check

What 110V buys you

All four run dual 110V/220V, and all four cut on 110V at reduced output. The SILATU cuts 12mm at 40A and 60PSI on 110V. The YESWELDER’s stated clean cut of 19/64 in is the 110V figure. The GUOZHI’s 1/4 in (12mm) figure is at 35A 110V 50PSI. A 110V circuit tops out in current: the YESWELDER is rated 5.6 KW, and the SILATU demands a 40-amp-or-higher breaker on a dedicated circuit at 220V. If the garage only has 110V, the SILATU’s 15A bottom end and the YESWELDER’s 20 to 55A output still give real cutting without rewiring.

When 220V is worth it

The full output needs 220V: 65A on the SILATU, 55A on the YESWELDER, 50A on the PRIMEWELD and GUOZHI. The GUOZHI states breakers up to 40A at 110V 35A and up to 30A at 220V 50A, so the 220V setting actually asks for a smaller breaker than its 110V setting. The PRIMEWELD states AC 110/220 plus or minus 15 percent, which is the widest stated input tolerance here. Factor a licensed electrician into the cost before buying if the garage has no 220V circuit; the full-output performance costs real wiring money.

What each listing suits

The YESWELDER suits the buyer who wants the longest warranty here with full pilot-arc and consumable features. The PRIMEWELD suits the buyer who wants one machine for cutting and welding, with the 3-year warranty as the tiebreaker. The SILATU suits the buyer chasing the thickest cuts at 65A with an air sensor and the widest current span. The GUOZHI suits the buyer who wants the lightest unit at 13 lb with 2T/4T controls. Match the pick to the thickest metal the garage actually cuts and the power it already has.
