Sealey Supermig 140amp Mig Welder

[Pinnerz]

Hey,

I was just wondering what people views are on this mig welder? I got offered this but i'm not fully clued up on all of it.

Suitable for welding with CO2, Argon or CO2/Argon mix.
Features a Forced Air Cooling System to slow transformer heating in order to increase duty cycle and a non-live torch to prevent the risk of accidentally striking an arc.
Supplied with a regulator suitable for our range of disposable or refillable gas cylinders (gas is not included).
Also includes spool of wire, contact tips 0.6 and 0.8mm.
Model No: SUPERMIG140
Welding Current: 30-140A
Wire Capacity: 0.7-5.0kg
Duty Cycle: 50% @ 55A, 20% @ 80A
Cooling System: Forced Air
Spot Welding Timer: No
Gas Type: CO2, Argon, CO2/Argon Mix
Torch: Non-Live
Power Input: 230V-1ph
Absorbed Power: 2.8kW
Case Size: Compact
Weight: 22kg

Are these crap figures? what thickness of steel would this weld up to? I don't really know how to work out the duty cycle. (I'm a complete noob to all of this and im just only starting to learn all this on a course atm)

Any advice would be extremely grateful! Thanks

I have one of these. Well my mate has one that I am borrowing for a while. We are running argon/c02 from a big BOC bottle, and it is really good. We have had no problems with it so far. I still struggle a bit on really thin stuff, but I think that is more to do with my skill. It can weld thick too given a decent setup.

Should be a reasonable m/c on bodywork if it goes down to 30A.

The duty cycle (20% @ 80A) suggests there's not a lot of grunt at the top end, so it will probably only weld thicker stuff - 3 to 4 mm - in short runs.

(On this thickness it will be set at around its top output, 135-140 Amps, which will have a duty cycle of only 1 minute of actual welding in every ten).

Don't let that put you off, hobby welding is often 5 or 10 seconds welding at a time making brackets and stuff. The rest is cleaning the job and getting it set up right between welds.

If the wire feed is good and everything else is running ok it should be a decent enough starter m/c if it's within your budget.
