Welding Power Source Duty Cycle And Overheating 6 Minutes Welding 4 Minutes Resting 4 Minutes Welding 6 Minutes Resting Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating. If unit overheats, thermostat(s) opens, output stops, and cooling fan runs. Wait fifteen minutes for unit to cool. Reduce amperage or voltage, or duty cycle before welding. Exceeding duty cycle can damage unit and void warranty. Overheating 0 15 A or V OR Reduce Duty Cycle Minutes duty1 4/95 – 150 215-A 60% Duty Cycle At 200 Amperes 40% Duty Cycle At 250 Amperes 2-3. Welding Gun Duty Cycle And Overheating CAUTION WELDING LONGER THAN RATED DUTY CYCLE can damage gun and void warranty. • Do not weld at rated load longer than shown below. • Using gasless flux cored wire reduces gun duty cycle. warn7.1 8/93 Duty Cycle is percentage of 10 minutes that gun can weld at rated load without overheating. 0 10 Minutes Definition .023 To .045 in (0.6 To 1.1 mm) Hard Or Flux Cored Wires 100% Duty Cycle At 200 Amperes Using CO2 100% Duty Cycle At 150 Amperes Using Mixed Gases .023 To .045 in (0.6 To 1.1 mm) Hard Or Flux Cored Wires 60% Duty Cycle At 300 Amperes Using CO2 60% Duty Cycle At 200 Amperes Using Mixed Gases Continuous Welding SB1.1 8/93 6 Minutes Welding 4 Minutes Resting 2-4.

Connecting Olympic 30A Gun The Olympic 30A welding gun connects directly to the 10-pin receptacle on the front of the welding power source – no adapter required. NOTE: Two welding guns may be connected to the welding power source at the same time, but only one welding gun may be in use at any one time. If the triggers of both welding guns are pulled at the same time, the weld output and wirefeed motor are disabled. 2-8. Setting Gun Polarity For Wire Type 1 Polarity Changeover Label Information Always read and follow manufacture’s recommended polarity. 1 3/4, 11/16 in Ref. 190 821-A Changing Polarity Wire Drive Assembly Lead Work Clamp Lead Positive Terminal Shown as shipped – Electrode Positive (DCEP): For solid steel, stainless steel, aluminum, or flux core with gas wires (GMAW). Negative Terminal Electrode Negative (DCEN): Reverse lead connections at terminals from that shown above for gasless flux core wires (FCAW). Drive assembly becomes negative. 1 3/4, 11/16 in Ref. 190 821-A Changing Polarity Wire Drive Assembly Lead Work Clamp Lead Positive Terminal Shown as shipped – Electrode Positive (DCEP): For solid steel, stainless steel, aluminum, or flux core with gas wires (GMAW).

Installing Gas Supply Ref. ST-148 265-B / ST-802 028 Tools Needed: Obtain gas cylinder and chain to running gear, wall, or other stationary support so cylinder cannot fall and break off valve. 1 Cap 2 Cylinder Valve Remove cap, stand to side of valve, and open valve slightly. Gas flow blows dust and dirt from valve. Close valve. 3 Cylinder 4 Regulator/Flowmeter Install so face is vertical. 5 Regulator/Flowmeter Gas Hose Connection 6 Welding Power Source Gas Hose Connection Connect customer supplied gas hose between regulator/flowmeter gas hose connection, and fitting on rear of welding power source. 7 Flow Adjust Typical flow rate is 20 cfh (cubic feet per hour). Check wire manufacturer’s recommended flow rate. 8 CO2 Adapter (Customer Supplied) 9 O-Ring (Customer Supplied) Install adapter with O-ring between regulator/flowmeter and CO2 cylinder. 1-1/8, 5/8 in CO2 Gas 8 9 3 1 2 4 5 7 1 2 3 Argon Gas OR 6 2-10.
