The duty cycle defines the number of minutes, within a 10 minute period, during which a given Welder can safely produce a particular welding current. For example, this Welder, with a 20% duty cycle at 105 Amps (setting Max 2), must be allowed to rest for at least 8 minutes after two minutes of continuous weld at 105 Amps.
•Failure to carefully observe duty cycle limitations can stress a Welder’s power generation system, contributing to premature Welder failure.
•This Welder is equipped with an internal thermal protection system to help prevent damage to the unit. When the unit overheats; it automatically shuts down, then returns to service when it cools down.
•Once the unit returns to service, follow a more conservative duty cycle routine to help prevent excess wear to the Welder.
1. | Always read and follow wire |

|
| manufacturer’s recommended | ||||||
|
| polarity. If using | ||||||
|
| secure the Argon/CO2 gas hose to | ||||||
|
| the rear of the MIG Welder. (If using | ||||||
|
| flux core wire, protective gas is not | ||||||
|
| required.) |

2. | Attach the Ground Cable with Clamp | |||||||
|
| (14) as close as possible to the metal | ||||||
|
| object to be welded. |
|

|
| welded with the Temperature |
