SELECT SUITABLE LOCATION

Locate the welder in a dry location where there is free circulation of clean air into the louvers in the back and out the front of the unit. A location that minimizes the amount of smoke and dirt drawn into the rear louvers reduces the chance of dirt accumulation that can block air passages and cause overheating.

Work Clamp Installation

Attach the work clamp per the following:

1.Unplug the machine or turn the power switch to the “OFF” position.

2.Insert the work cable terminal lug with the larger hole through the strain relief hole in the work clamp as shown in Figure A-3.

STACKING
