All our Supermig models are suitable for welding with CO2, Argon or CO2/Argon mix. Each uses a Forced Air Cooling System to slow transformer heating in order to increase duty cycle. A non-live torch is fitted to prevent the risk of accidentally striking an arc. Model No. SUPERMIG150 and above are supplied with an industrial Argon/CO2 regulator. A contract for the supply of gas should be arranged with your local gas distributor.Model No:SUPERMIG130Welding Current:30-130AWire Capacity:0.7-5kgDuty Cycle:100% @ 30A, 60% @ 45A, 40% @ 65A, 20% @ 80ACooling System:Forced AirSpot Welding Timer:NoGas Type:CO2, Argon, CO2/Argon MixTorch:3mtr Non-LiveSupply:230VAbsorbed Power:2.8kWCase Size:CompactWeight:20kg
